Mathematical model analysis of wheatcultvars ecotypes evolution, through the 2005-2006 study of five wheat-522 samplesof wheat Ecological Survey, take hypothesis testing statistical methods to the analysisof the regional differences were significant problems 1 while wheat cultvars, and late-maturing varieties of early maturing varietiescan not meet the needs of production, gradually been eliminated, while early varietiesto be preserved.

本论文研究主要结论有： 1、在品种更替过程中，早熟品种和晚熟品种所占比例分别由80％和30％降低为零，两种生态型逐步遭到了淘汰，而中早熟品种得到了保留，由1978年的零分布增加到2005年的46％。 2、偏春性和冬性品种分别1988年至1996年和1991年至1993年和的变化较大，其动态变化度分别为1和0.66。

The near isogenic lines containing the S5n allele from different original WCVs . and genetic background from japonica variety Balilla were crossed with 20 indica-japonica varieties representing different ecotypes, the results indicated that genetic effect of S5n from different wide compatibility varieties was not completely same, and that the compatibility power and compatibility spectrum of near isogenic lines carrying S5n from different donors were different.

Higher Ca distributed in bulliformcell than in mesophyll cell and bundle sheath cell of dune reed, higher Mg distributedin mesophyll cell and higher K, Na and Cl distributed in sheath cell HigherNa and Mg distributed in mesophyll than in bulliform cell and bundle sheathcell of light salt meadow reed, and higher K, Ca and Cl distributed in itsbundle sheath cell. Higher Na and Mg distributed in bulliform cell than in mesophyllcell and bundle sheath cell of heavy salt meadow reed, higher K, Ca and Cl distributedin its mesophyll cell. This paper discussed the distribution conditions of theabove five ions in leaf cell of the four reed ecotypes and the meaning ofphysiological adaptation to habitat in detail.

The results showed that rice straw growth and fascicular alteration interacted when water was deficient. It not only affected the transportation of nutritious substance from rhizine and leaf to kernel, but also led to the decrease of agronomic characters and yield. 4 ecotypes of rice vascular bund...

结果表明：水分不足对稻秆及秆中维管束的影响是相互的：稻秆的发育情况影响了维管束变化，同时维管束的变化影响了稻秆的发育，最终影响营养物质从根部、叶部向籽粒运输，从而使结粒数、稔实率、千粒重、产量下降。4种生态型水稻维管束系统与一次及高次枝梗数目、结粒数、千粒重等有类似的相关性，而且水分不足时反应出相同的结果，说明土壤水分对维管束系统的分化有很大的影响，水分不足将使维管束面积变小，维管束比增大，从而使产量变小。
