转基因苹果研究进展

十多年来,转基因技术以其独特的魅力在苹果上得到了迅速发展.目前,农杆菌介导法是苹果上应用的主要转化方法,叶片再生不定芽途径是被广泛应用的受体系统.影响这一受体系统的主要因素有基因型、外植体的来源、叶片发育阶段及生理年龄、培养条件以及抗生素等.而菌株的类型、侵染时间、共培养的时间和条件、酚类物质及转化植株的选择方式等则影响基因的转化.已有多种标记基因和目的基因转入苹果中,且遗传分析表明外源基因能够稳定遗传.但依然存在转化效率不高、外源基因表达强度不够、可转化的目的基因有限及对转化植株的选择不够重视等诸多问题.综合有关文献对上述问题进行了讨论并对转基因苹果的前景进行了展望.
套袋、喷钙对酥梨果实矿质营养和品质的影响 

酥梨果实套袋后,对叶鲜、干重,叶绿素和N、P、K含量,未发现有明显不良影响.而成熟果实中K、Ca、Mg含量值则分别下降10.6%、58%、9.3%,总糖下降0.9%,维生素C下降7.4mg/100g.平均后果变小,减产约13.4%.若采取喷钙后套袋,同单纯套袋相比,上述各项指标含量,均有明显提高,甚至接近或略超过CK处理的含量.对不套袋的梨果喷施(3种)钙肥,与CK相比,上述各项指标含量均有明显提高,增产2.9%～7.4%.3种钙肥喷施的综合效果,腐殖酸钙和高能钙稍好于补钙王.

Early Tracking Behavior in Small-field Quintessence Models

We study several quintessence models which are exotic at Q = 0, anduse a simple constraint Q ≥ H/2π to check when they enter the tracking regime,disregarding the details of inflation. We find that it can also give strong constraintsfor V = V_0Q~(-α), which has to enter the tracking regime after lnz ～ 10, while forthe supergravity model V = V_0Q~(-α)exp(kQ~2/2), the constraint is much weaker. Forthe exponential form of inverse power-law potential V = V_0exp(λ/Q), it exhibits noconstraints.
How Does the Partitioning of Evapotranspiration and Runoff between Different Processes Affect the Variability and Predictability of Soil Moisture and Precipitation?

Water stored as part of the land surface is lost to evapotranspiration and runoff on different time scales,and the partitioning between these time scales is important for modeling soil water in a climate model.Different time scales are imposed on evapotranspiration primarily because it is derived from differentreservoirs with different storage capacities, from the very rapid evaporation of canopy stores to the slowremoval by transpiration of rooting zone soil moisture. Runoff likewise ranges in time scale from rapidsurface terms to the slower base-flow. The longest time scale losses of water determine the slow variationof soil moisture and hence the longer time scale effects of soil moisture on precipitation. This paper showswith a simple analysis how shifting the partitioning of evapotranspiration between the different reservoirsaffects the variability of soil moisture and precipitation. In particular, it is concluded that a shift toshorter time scale reservoirs shifts the variance of precipitation from that which is potentially predictableto unpredictable.
Quick Measurement of CH4, CO2 and N2O Emissions from a Short-Plant Ecosystem

Combining improved injector, gas line and valve-driving models, a gas chromatograph (GC) equippedwith Hydrogen Flame Ionization Detector (FID) and Electron Capture Detector (ECD), can measureCH4, CO2, and N2O simultaneously in an air sample in four minutes. Test results show that the systemhas high sensitivity, resolution, and precision; the linear response range of the system meets the requirementof flux measurements in situ. The system is suitable for monitoring fluxes of the main greenhouse gases ina short-plant field since it is easy to use, efficacious, and constant and reliable in collecting data.
Prediction of Typhoon Tracks Using Dynamic Linear Models

This paper presents a study on the statistical forecasts of typhoon tracks. Numerical models havetheir own systematic errors, like a bias. In order to improve the accuracy of track forecasting, a statisticalmodel called DLM (dynamic linear model) is applied to remove the systematic error. In the analysis oftyphoons occurring over the western North Pacific in 1997 and 2000, DLM is useful as an adaptive modelfor the prediction of typhoon tracks.
Influence of the Mascarene High and Australian High on the Summer Monsoon in East Asia: Ensemble Simulation

By using a nine-level atmospheric general circulation model developed at the Institute of AtmosphericPhysics (IAP 9L AGCM), two sets of numerical experiments are carried out to investigate the influenceof the Mascarene high (MH) and Australian high (AH) over the southern subtropics upon the East Asiansummer monsoon circulation and summer precipitation in East Asia. The use of ensemble statistics isadopted to reduce the simulation errors. The result shows that with the intensification of MH, the Somalilow-level jet is significantly enhanced together with the summer monsoon circulation in the tropical Asiaand western Pacific region. Furthermore, the anticyclonic anomaly in the tropical western Pacific to theeast of the Philippines may induce a weak East-Asia-Pacific teleconnection pattern. In the meantime,geopotential height in the Tropics is enhanced while it is reduced over most regions of mid-high latitudes,thus the northwestern Pacific subtropical high at 500 hPa extends southwestward, resulting in more rainfallin southern China and less rainfall in northern China. A similar anomaly pattern of the atmosphericcirculation systems is found in the experiment of the intensification of AH. On the other hand, because thecross-equatorial currents associated with AH are much weaker than the Somali jet, the anomaly magnitudecaused by tihe intensification of AH is generally weak, and the influence of AH on summer rainfall in Chinaseems to be localized in southern China. Comparison between the two sets of experiments indicates thatMH plays a crucial role in the interactions of general atmospheric circulation between the two hemispheres.
The Influence of Vegetation Cover on Summer Precipitation in China: a Statistical Analysis of NDVI and Climate Data

This study provides new evidence for the feedback effects of vegetation cover on summer precipitation in different regions of China by calculating immediate (same season), and one-and two-season lagged correlations between the normalized difference vegetation index (NDVI) and summer precipitation. The results show that the correlation coefficients between NDVI in spring and the previous winter and precipitation in summer are positive in most regions of China, and they show significant difference between regions. The stronger one-and two-season lagged correlations occur in the eastern arid/semi-arid region, Central China,and Southwest China out of the eight climatic regions of China, and this implies that vegetation cover change has more sensitive feedback effects on summer precipitation in the three regions. The three regions are defined as sensitive regions. Spatial analyses of correlations between spring NDVI averaged over each sensitive region and summer precipitation of 160 stations suggest that the vegetation cover strongly affects summer precipitation not only over the sensitive region itself but also over other regions, especially the downstream region.
Establishing a Ultraviolet Radiation Observational Network and Enhancing the Study on Ultraviolet Radiation

On the basis of analyzing observational data on solar radiation, meteorological parameters, and totalozone amount for the period of January 1990 to December 1991 in the Beijing area, an empirical calculationmethod for ultraviolet radiation (UV) in clear sky is obtained. The results show that the calculated valuesagree well with the observed, with maximum relative bias of 6.2% and mean relative bias for 24 months of1.9%. Good results are also obtained when this method is applied in Guangzhou and Mohe districts. Thelong-term variation of UV radiation in clear sky over the Beijing area from 1979 to 1998 is calculated, andthe UV variation trends and causes are discussed: direct and indirect UV energy absorption by increasingpollutants in the troposphere may have caused the UV decrease in clear sky in the last 20 years. With theenhancement of people's quality of life and awareness of health, it will be valuable and practical to providUV forecasts for typical cities and rural areas. So, we should develop and enhance UV study in systematicmonitoring, forecasting, and developing a good and feasible method for UV radiation reporting in China,especially for big cities.

An Improvement of the Mass Flux Convection Parameterization Scheme and its Sensitivity Tests for Seasonal Prediction over China

A modified cumulus parameterization scheme, suitable for use in a seasonal forecast model, is presented. This parameterization scheme is an improvement of the mass flux convection scheme developed by Gregory and Rowntree (1989; 1990). This convection scheme uses a "bulk" cloud model to present an ensemble of convective clouds, and aims to represent shallow, deep, and mid-level convection. At present,this convection scheme is employed in the NCC T63L20 model (National Climate Center, China Meteorological Administration). Simulation results with this scheme have revealed some deficiencies in the scheme,although to some extent, it improves the accuracy of the simulation. In order to alleviate the deficiencies and reflect the effect of cumulus convection in the actual atmosphere, the scheme is modified and improved.The improvements include (i) the full estimation of the effects of the large-scale convergence in the lower layer upon cumulus convection, (ii) the revision of the initial convective mass flux, and (iii) the regulation of convective-scale downdrafts. A comparison of the results obtained by using the original model and the modified one shows that the improvement and modification of the original convection scheme is successful in simulating the precipitation and general circulation field, because the modified scheme provides a good simulation of the main features of seasonal precipitation in China, and an analysis of the anomaly correlation coefficient between the simulation and the observations confirms the improved results.
The Possible Influences of the Increasing Anthropogenic Emissions in India on Tropospheric Ozone and OH

A 3-D chemical transport model (OSLO CTM2) is used to investigate the influences of the increasing anthropogenic emission in India. The model is capable of reproducing the observational results of the INDOEX experiment and the measurements in summer over India well. The model results show that when Nox and CO emissions in India are doubled, ozone concentration increases, and global average OH decreases a little. Under the effects of the Indian summer monsoon, Nox and CO in India are efficiently transported into the middle and upper troposphere by the upward current and the convective activities so that the Nox, CO, and ozone in the middle and upper troposphere significantly increase with the increasing Nox and CO emissions. These increases extensively influence a part of Asia, Africa, and Europe, and persist from June to September.
The Performance of Atmospheric Component Model R42L9 of GOALS/LASG

This paper examines the performance of an atmospheric general circulation model (AGCM) de-veloped at the State Key Laboratory of Numerical Modeling for Atmospheric Sciences and Geophysi-cal Fluid Dynamics, Institute of Atmospheric Physics (LASG/IAP). It is a spectral model truncated atR42(2.8125°long * 1.66°lat) resolution and with nine vertical levels, and referred to as R42L9/LASG here-after. It is also the new version of atmospheric component model R15L9 of the global ocean-atmosphere-land system (GOALS/LASG). A 40-year simulation in which the model is forced with the climatologicalmonthly mean sea surface temperature is compared with the 40-year (1958 97) U.S. National Centerfor Environmental Prediction (NCEP) global reanalysis and the 22-year (1979-2000) Xie-Arkin monthlyprecipitation clinatology. The mean DJF and JJA geographical distributions of precipitation, sea levelpressure, 500-hPa geopotential height, 850-hPa and 200-hPa zonal wind, and other fields averaged for thelast 30-year integration of the R42L9 model are analyzed. Results show that the model reproduces well theobserved basic patterns, particularly precipitation over the East Asian region. Comparing the new modelwith R15L9/LASG, the old version with coarse resolution (nearly 7.5°long * 4.5°lat), shows an obviousinprovement in the simulation of regional climate, especially precipitation. The weaknesses in simulationand future improvements of the model are also discussed.
The Northward Shift of Climatic Belts in China During the Last 50 Years and the Corresponding Seasonal Responses

Along the meridian of 105°E, the Chinese region are divided into two parts, east and west. The results show that in the east part of China the temperate extratropical belt, the warm extratropical belt, and the northern subtropical belt shift northward significantly, whereas the middle subtropical belt and the southern subtropical belt have less or no change. As for the northern subtropical belt, the maximal northward shift can reach 3.7 degrees of latitude. As for the warm extratropical belt, along the meridian of 120°-125°E, the maximal northward shift can reach 3-4 degrees. In the west part of China, each climatic belt changes little. Only in the Xinjiang area are the significant northward shifts. Correspondingly, it is found that in the last 50 years the traditional seasons have changed. For Beijing, Hailar, and Lanzhou, in general, summer becomes longer and winter shorter over the last 50 years. Summer begins early and ends late with respect to early 1950s. Contrary to the summer, winter begins late and ends early with respect to early 1950s. Furthermore, spring and autumn have changed over the last 50 years: with respect to early 1950s spring begins early and autumn begins late.
Dependence of Hurricane Intensity and Structures on Vertical Resolution and Time-Step Size

In view of the growing interests in the explicit modeling of clouds and precipitation, the effects of varyingvertical resolution and time-step sizes on the 72-h explicit simulation of Hurricane Andrew (1992) arestudied using the Pennsylvania State University/National Center for Atmospheric Research (PSU/NCAR)mesoscale model (i.e., MMS) with the finest grid size of 6 km. It is shown that changing vertical resolutionand time-step size has significant effects on hurricane intensity and inner-core cloud/precipitation, butlittle impact on the hurricane track. In general, increasing vertical resolution tends to produce a deeperstorm with lower central pressure and stronger three-dimensional winds, and more precipitation. Similareffects, but to a less extent, occur when the time-step size is reduced. It is found that increasing thelow-level vertical resolution is more efficient in intensifying a hurricane, whereas changing the upper-levelvertical resolution has little impact on the hurricane intensity. Moreover, the use of a thicker surface layertends to produce higher maximum surface winds. It is concluded that the use of higher vertical resolution,a thin surface layer, and smaller time-step sizes, along with higher horizontal resolution, is desirable tomodel more realistically the intensity and inner-core structures and evolution of tropical storms as well asthe other convectively driven weather systems.

Joint Propagating Patterns of SST and SLP Anomalies in the North Pacific on Bidecadal and Pentadecadal Timescales

Wavelet analyses are applied to the Pacific Decadal Oscillation index and North Pacific index forthe period 1900 2000, which identifies two dominant interdecadal components, the bidecadal (15-25-yr)and pentadecadal (50-70-yr) modes. Joint propagating patterns of sea surface temperature (SST) andsea level pressure (SLP) anomalies in the North Pacific for the two modes are revealed by using thetechniques of multi-channel singular spectrum analysis (MSSA) and linear regression analysis with theglobal sea surface temperature (GISST) data and the northern hemispheric SLP data for the commonperiod 1903-1998. Significant differences in spatio-temporal structures are found between the two modes.For the bidecadal mode, SST anomalies originating from the Gulf of Alaska appear to slowly spreadsouthwestward, inducing a reversal of early SST anomalies in the central North Pacific. Due to furtherwestward spreading, the SST variation of the central North Pacific leads that of the Kuroshio-OyashioExtension (KOE) region by approximately 4 to 5 years. Concomitantly, SLP anomalies spread over mostparts of the North Pacific during the mature phase and then change into an NPO(North Pacific Oscillation)-like pattern during the transition phase. For the pentadecadal mode, SST anomalies develop in thesoutheast tropical Pacific and propagate along the North American coast to the mid-latitudes; meanwhile,SST anomalies with the same polarity in the western tropical Pacific expand northward to Kuroshio and itsextension region; both merge into the central North Pacific reversing the sign of early SST anomalies there.Accompanying SLP anomalies are characterized by an NPO-like pattern during the mature phase whilethey are dominant over the North Pacific during the transitional phase. The bidecadal and pentadecadalmodes have different propagating patterns, suggesting that the two interdecadal modes may arise fromdifferent physical mechanisms.

A Linear Diagnostic Equation for the Nonhydrostatic Vertical Motion W in Severe Storms

A linear diagnostic equation for the nonhydrostatic vertical motion W in severe storms is derived in the Cartesian-earth-spherical coordinates. This W diagnostic equation reveals explicitly how forcing factors work together to exert influence on the nonhydrostatic vertical motion in severe storms. If high-resolution global data are available in Cartesian coordinates with guaranteed quality, the Lax-Crank-Nicolson scheme and the Thomas algorithm might provide a promising numerical solution of this diagnostic equation. As a result, quantitative analyses are expected for the evolution mechanisms of severe storms.

Least-squares solutions of X~T AX=B over positive semidefinite matrixes

This paper is mainly concerned with solving the following two problems: Problem I. Given X∈R~(n*m), B∈R~(m*m). Find A∈P_n such that ||X~TAX-B||_F = min, where P_n = {A∈R~(n*n|x~T Ax≥0, ∨x∈R~n}. Problem II. Given A-tilde∈R~(n*n). Find A-tilde∈SE such that ||A-tilde-A-tilde||F = min ||A-tilde-A||F, A∈S_E where ||·||_F is Frobenius norm, and S_E denotes the solution set of Problem I. The general solution of ProblemI has been given. It is proved that there exists a unique solution for Problem II. The expression of this solution for corresponding Problem II for some special case will be derived.
