JONATHAN STORAGE TESTS.

Two years ago this fall the Cow
eminent sent one of their storage
I experts to Payette to investigate the
/ complaint of Eastern dealers that
too many of our Jonathans arrived
there oyer-ripe. This storage eH-
pert, Mr.. w G. Quick, and two OF
our local growers, Messrs. David
Jones and W.. A. Moreland, the Pay
cite Cold Storage and the County
Agent co-operated in this test.
Quoting Mr.. Quick; Picking at
the right time and storing promptly
are two of the most important fac
tors affecting the keeping quality of
apples. Rome Beauties picked be-
fore they have reached proper ma
turity scald badly in storage, while
Jonathans picked too late become
punkey and decay. A still more
important cause of decay in Jona-
thans is the practice of delaying
storage for sometime after the fruit
is picked.
The tests were made with both
Jonathans and Romes but only the
Jonathan data interests us now.
The bases for the tests were as fol-
lows:
Lot 1-Jonathans, immediate
cold storage; picked, packed and
cold stored Oct. 10th.
Lot 2-Jonathans, delayed stor-
age; picked Oct 10th but packed
and cold. stored Oct. goth.
All the Jonathans in these tests
should have been picked earlier for
best keeping quality as the results
indicate, but the expert desired av-
erage Payette conditions and Octo-
Der 10th was at the height of the
Jonathan harvest. The storage was
better than our orchardists have
but was such as commercial Jona-
thans have under refrigerated con-
ditions. The temperature at the
Payette Cold. Storage was constant
at about 33 degrees such as Chicago
and New York dealers maintain.
The first storage inspection was
made Jan Q, 1918. At that time
the Jonathans were badly speckled
with Jonathan spot, Ia round brown
ish blotch that effects only the skin
of the apple). Immediately after
the experts inspection these Jona7
thehs were removed to a so degree
cellar for ten days. Another in
spection on Jan. 18th confirmed the
first inspection as follows:
Lot 1-Jonathans Immediately
stored: Picked, packed, cold, stored
Oct. 10th, Fifteen per cent decayed
because of over-ripeness.
Lot Jonathan delayed storage:
Picked Oct. 10th; packed and cold
stored Oct. goth. Fifty-five per cent

from year to year. 1t is seldom the
for the upper south half of a
tree as it is on the lower north half
Of tree. 1t is even difficult to |
designate the proper time by apple |
appearance. In general, however,
With keeping-quality Jonathans
hould be picked when the under
leath or ground color turns from
eaf green to 'yellowish green and
ust when the flesh is beginning to
urn from white to tinge of yell
ow".
