Abstract

A spec trophotome trie and colorimetric study has been made on the

leaves of three species of trees (Beech, Dogwood, and White Oak), one shrub (Mountain Laurel) and one herb (Milkweed), stored in metal containers with tightly fitting metal covers for intervals of 1? hours to

12 days. This was done to determine the color variations that occur

in these representative types of foliage during storage, and to predict

if possible, the color variations that may occur in similar and otter

types of foliage during periods of shipment in similar covered metal

containers.

1° Introduction

The overall objective of this Air Force investigation is stated as follows? *! To develop by visible, near infrared,, and near ultraviolet

spec trophotometry, methods for the detection of objects from color

reconnaissance | to study the colors,, tonal contrasty and color separation

necessary in aerial photography to yield maximum information! to determine

the wavelength region at which the film manufacturer should strive to

obtain maximum sensitivity to yield clear separation of an object from its

adjacent area rather than to yield true color fidelity! to determine the

characteristics required in a sensitized material for the rapid and accurate

extraction of this information85 .

The present report pertains to the natural background of many aerial

photographs! namely, the leaves of trees,, shrubs and herbs® It especially

pertains to leaves picked in an -area of aerial interest and shipped to a distant laboratory for study. This stuc^r is made to determine, if possible,

the suitability of well capped metal containers for shipping and storing

foliage for subsequent spec trophotometrie study (1) by measuring the color

changes that leathery (coriaceous) leaves and thin (membranous) leaves go

through during shipment in a metal container! (2) by measuring the rate of

change and stages for different types of leaves? (a) leaves showing incipient fall coloring (Beech) , (b) leaves showing advanced fall coloration (Dogwood), (c) leaves shewing no visible fall coloration (White Oak),

and (d) evergreen leaves (Mountain Laurel)! and (3) by comparison of these

,0 changes with those of leaves of the same species charged naturally in sunlight.

The method of measurement and computation is that requested in the

original project proposal and used in a previous report on this project M*.

To fulfill this request, spectral directional reflectance measurements have been made for the visible and near infrared spectral regions,

lj.00 to 1080 millimicrons, for both the ventral and dorsal sides of 32

specimens of foliage of $ species of tree, shrub, and herb stored in a large metal can with a tight fitting metal top* Colorimetric computations

have been made for the visible spectrum, U00 to 75>0 millimicrons, for both

sides of the foliage specimens to obtain the chromaticity coordinates and

daylight reflectances for the International Commission on Illumination

(C.I.E.) standard observer and coordinate system for Source C, representative of average daylight. In addition, these C.I.E. chromaticity coordinates

and daylight reflectances have been converted into terms of the Munsell renotation system and into the ISCC-NBS color designations. Illustrations

nates, Mansell renotatLons, and color differences caused by the storage

of foliage of Beech* Dogwood* Mountain Laurel* and White Oak for periods

of approximately 1* 2, k3 5* 7$ 10, and 12 days, and the foliage of

Milkweed for periods of approximately 7, and 12 days. An additional

set of measurements was made on foliage of a Beech tree, stored for

approximately 5> days, the branch of which had been incompletely broken

from the tree about one month before the measurement.

It is believed that this type of information win assist in selecting

a suitable method for storing and transporting foliage for subsequent

laboratory analysis, and that it is a necessary step towards attaining the

overall objective of this investigation.

II. Material

The foliage of this experiment was collected by Dr, Hugh T, O’Neill

from trees and plants located at the site of his field laboratory at the

head of Broad Creek of the South River, a tributary of the Chesapeake Bay,

near Annapolis, Maryland. The trees were designated by him ass Beech

(Fagus grandifolia IShrh. ), Dogwood (Cornus florida L.)? and White Oak

(Quemis alba L»)| the shrub ass Mountain Laurel (Kalmia latifolia L.)j

and the herb ass Milkwood (Aselepias syriaea L.)»

A large number of leaves of each species had been collected at each

time of picking, and when received at the NBS the leaves had been stored

in a 5 gallon metal container with a tightly fitting metal top. They were

arranged in seven layers in the container, separated by layers of newspapers. All of the leaves in a given layer were picked at the same time.

Each species carried an identification label with the indicated date and

time of picking and storage. The extra, unmeasured leaves served to maintain fairly constant storage conditions within the container daring the

period of storage especially after a series of sets of leaves had been

removed for measurement. To extend the time scale of storage, the specimens collected last were measured firsts those collected next to last were

measured seconds and so forth until those collected first were measured last,

A listing of the date and time of picking, the date and time of measurement, and the approximate number of hours that each set of leaves remained in storage, is given in Table I,

III. Spec trophotome trie Measurements

Seven sets of measurements of spectral directional reflectance for the

visible and near infrared spectral regions, k00 to 1080 millimicrons, were

made on both the ventral and the dorsal sides of 32 specimens of foliage

on a General Electric recording spec trophotorae ter [2, 3^ for the condition

of included specular component of the reflected radiant energjr. Slits of

approximately 10 millimicrons of spectral width were used for the measure-
[IIIIIII
$

-laments in tbs visible spectrum I4OO to 7^0 millimicrons, and 20 millimicrons

of spectral -width for the near infrared spectrum 730 to 1080 millimicrons.

The first set of measurements was made on the morning that the speciments were received at the KBS® Those leaves that had been in storage for

approximately 1? hours, were removed from the tin can, and the lid was

'immediately replaced. They were arranged roughly according to hue, and

representative specimens were selected as measuring and backing leaves for

each species. In each case, the measurements for both the ventral and the

dorsal sides were made on the selected measuring leaf. For the ventral

side measurements, the ventral side of the backing leaf was placed against

the dorsal side of the measuring leaf, and for the dorsal side measurements,

the reversed sides were placed together. An effort was made to measure

the same area of leaf on each side. Each pair of samples was backed with

black paper on a wooden block.

After each set of measurements, the measuring and backing samples of

each species were filed in separate manila envelops for possible future

reference while "the excess leaves were discarded. It will be noted,

accordingly, that the measurements at the different time intervals are on different samples.

The same procedure described for the first set was followed for the

remaining sets of leaves. The time schedule for these measurements is

given in Table I.

X¥. Speetrophotometric Results

The results of this spectrophotometric study of the changes of spectral

directional reflectances of leaves of trees and plants stored for periods

of time in covered metal containers are shown on the ll*. Ozalid prints of

the original recordings in Appendix A cf this report. There are 7 graphs

of the visible spectrum and 7 graphs of the near infrared speetrumj for each

set of measurements the infrared graph sheet follows its companion visible

spectrum graph.

Values of spectral directional reflectance were read at each ten

millimicron interval from I4OO to 1080 millimicrons from each of the 6)4

spectrophotometric curves of the ventral and dorsal sides of 5> species of

leaves shown on the l!i graph sheets of Appendix A. These values are listed

in Appendix B of this report. For wavelengths 730, 7U0 and 750 millimicrons, which spectral region appears on both the visible and on the near infrared graph sheets, the average values for both determinations are reported. The tables of Appendix B are arranged in groups alphabetically by

order of tree, shrub, or herb common name and with increasing times of

storage for each species making up the group.

The data from each of these groups of measurements have been assembled

arid plotted to show how each side of each leaf changes spectrally for the

#
'

1
various periods of storage of this experiment® These illustrations are shown for both the visible and near infrared spectral regions, for all

but one of the samples studied, in Figures 1 through 9» The exception

was the sample taken from the Beech tree branch that had been incompletely

broken® The data, from this sample did not fit into the systematic arrangement of the spectral data® However, all of the computations have been

made and are listed for this sample in the tables of data. The leaf

behaved like a leaf that had aged considerably more than the other leaves

of its same species of this study.

The remainder of this report deals with the visible spectrum part of

these measurements and with their conversions into chromaticity coordinates*

daylight reflectances* Munsell renotations, ISCC-NBS color designations,

and color differences. M

V. Colorimetric Computations

The spectral directional reflectances for the visible spectrum 380

to 75>0 millimicrons, for the 32 determinations made on the ventral side,

and the 32 determinations made on the dorsal side, of the 5 foliage

species kept in storage were integrated into the International Commission

on Illumination (G.I.E.) standard observer and coordinate system [51 for

Source C, representative of average daylight. These colorimetric computations yielded the chromaticity coordinates and daylight reflectances

listed in Table II of this report.

The area of the C.I.E. chromaticity diagram covered by each of the

five species of foliage studied in this storage experiment are shown in

Figure 10. Qilargements of each of these areas are shown, in Figures 11

through 15 . The numbers used to designate the points in these graphs are those assigned in Table I and the Index to Appendix A.

VI. Munsell Renotations and ISCC-NBS Color Designations

By the use of the above C.I.E. chromaticity coordinates and daylight

reflectances of the 32 sets of ventral and dorsal sides of stored foliage,

the Mansell renotations were obtained from graphs of conversion from the

C.I.E. system to the Munsell system £61 . These Munsell renotations were

then converted into terms of the ISGG-NBS color designations [7] . Both

the Munsell renotations and the ISCG-NBS color designations of all 6I4 determinations on the ventral and the dorsal sides of stored leaves are shown in Tables III and IV, respectively.

The colorimetric changes in these leaves are shown in the illustra°

tions of the vertical and horizontal projections of ideal Munsell color

space. Figures 16 through 20. The numbers assigned to the plotted points

are the same as used on the CoI.E. diagrams, in Table I and in the Index

to Appendix A.

¥11* Color Difference

From the Mansell renotations of the 6k determinations of the ventral

and the dorsal sides of stored leaves., color differences in terms of NBS

units, IS EL, were computed by means of the Balinkin formula C8i, for all

of the determinations of each species of leaf relative to that of the

initial determination. For all samples except the Milkweed sample the

initial determination was made after the leaf had been in storage for

1? hours. For the Milkweed sample the reference point was the determination at storage time 122 hours as we had no sample previous to this time.

The Beech sample from the broken branch was referenced to the normal sample

at 17 hours for lack of other data.

These 5k color differences are tabulated in Table V, and plotted

against time in storage for each of the five species of leaves studied

in Figures 21 through 25>* For convenience two time scales are used,

the one at the bottom of the graph in hours, and the one at the top in

days, of storage*

It should be noted that this is the only report in this series in

which the Balinkin formula for the determination of color difference is

used. In NBS Report U322 and in the rest of the reports of this series,

the Godlove 03 formula is used. The Balinkin formula is somewhat easier

to use and is sufficiently accurate in this case since the samples of the

present report have relatively small changes in hue* Where large changes

in hue are pres•art, the use of the Godlove formula results in color dif=

ference evaluations more closely approximating the visual estimates of

color differences.

A series of especially selected leaves of trees, a shrub, and an

herb have been stored in metal containers with tight fitting metal lids

and then measurements of spectral directional reflectance were made for

both the ventral and the dorsal sides for the visible and the near infrared spectral regions, UOG to 1080 millimicrons. Thus a record was obtained

of the spectral change that these leaves underwent in storage.

The visible spectral data were then converted into colorimetric terms

for comparative purposes* These conversions were to C.I.E. standard

observer and coordinate system, then into the Munsell renotation system,

the ISCC-NBS color designation system, and finally into NBS AE terms of

color differences between the initial determination and each successive

determination on each side of each leaf*

These extensive data have been illustrated in 2$ figures and tabulated

in 5 tables, resulting from lU original spectr ©photometric recordings and

6.U tables of spectral data for the visible and near infrared spectra included in Appendices A and B of this report*

He Conclusions

From this study of specially selected leaves stored in large metal

containers with tightly fitting metal lids for periods of 17 hours to

12 days,, it is evident that slight changes in the color of two (Beech

and Dogwood) of the five species of leaves begin almost immediately

upon storage. As samples !,uns tored” were not submitted,, data could not

be obtained but it is almost certain that color changes started well in

advance of the first measurement at ?! over-night18 or after 17 hours of

storage

•

There is a strong indication that the thick leathery (coriaceous)

leaves change very little if at all during storage* The differences

indicated in Table V and Figure 2k for Mountain Laurel are possibly due

to variation of the leaves taken from the same branch. Furthermore,

White Oak leaves changed but little up to $0 hours in storage* Likewise,

small color differences are indicated in Table V and Figure 23 for Milkweed leaves but it is possible that larger changes occurred during the

first 122 hours of storage for which no samples were available.

The Beech leaves, which showed the incipient fall coloring, changed

more rapidly during the first two days of storage than any of the other

leaves. However, after four days of storage, the White Oak leaves that

had shown no visible fall coloration prior to storage, suddenly changed

quite rapidly and between the fourth and seventh days in storage showed

the greatest changes® For the first 90 hours., the Beech leaves in storage

changed more rapidly than the Dogwood leaves. After 90 hours in storage,

the rate of change, for these two sets of leaves was about the same.

The changes in the tree leaves of this study are the same as in sun- light £ 9j | that is, from green to brown.. The same is true for the dorsal

side of the dogwood leaves. However, the ventral sides of these Dogwood

leaves were red initially and in storage this red color changed from grayish reddish brown through grayish yellowish brown to brownish gray. The

dorsal sides of these same leaves changed fir am moderate olive through

light olive brown to grayish yellowish brown.

The indicated changes in. the tree leaves in storage are variable and

erratic for both hue and saturation. The indicated changes of the shrub

and herb leaves are fairly constant in hue but erratic in saturation.

Some, and perhaps all, of this variation is ascribable to the use of

separate specimens for each storage period.

The spec trophotome trie changes (Figures 1 to 9 and Appendices A and B) are not always the same for both sides of the same leaves. The major

changes in all cases of the leaves studied are between $00 and 600 milli-
.
- 8 -

mierons in the visible spectrum and between 7!?0 and 900 millimicrons

in the near infrared spectrum. In all specimens studied, except the

White Oak and Mountain Laurel <, the water absorption band at 980 millimicrons disappeared between the 1? and the k9 hour storage periods a The White Oak leaves showed slightly more resistance to this loss of

water but they also had this absorption band disappear between h9 and

90 hours of storage. The Mountain Laurel curves showed this water

band throughout the series of measurements even to the 282 hour period.

The practice of shipping and storing leaves in well capped metal

containers for subsequent spectrophotometric study would appear from

these results to be satisfactory for tough leathery leaves, such as the Mountain Laurel, and also for storage of White Oak leaves for not

more than two daysj but it is unsatisfactory for Beech and Dogwood

leaves. Whether this conventional method of shipping and storage is

satisfactory for Milkweed leaves was not decided by this test. It is

possible that the practice of dry shipment and storage of leaves

should be supplanted by the practice of shipping them soaked in water.

Note from NBS Report U322 that White Oak leaves kept soaked in water

remained substantially unchanged for over 300 hours, although shipment

in tightly closed dry metal containers permitted a substantial change

after only 90 hours.
