为分析普通小麦-天兰冰草部分双二倍体-远中2号(2n=54)的染色体构成，用生物素(biotin-16-dUTP)标记天兰冰草染色体组DNA作为探针，以普通小麦品种中国春染色体组DNA为封闭DNA，与远中2号的有丝分裂中期染色体DNA进行了分子原位杂交。

In grain-filling stage, the qP values of evolutionary wheats decreased under water stress, while Shan253 and Changwu134 hadn't decreased, indicated that the effect of water stress on the re-oxidation in Q-A of modern wheat was slight, while before this stage, the electron transport from PSⅡto QA restrained by water stress was main factor of photosynthesis non-stomata limitation to modern wheat; The qNP values of hexaploid were higher than diploid and tetraploid wheat, indicated that the ability of using light energy

随小麦由二倍体向四倍体、六倍体及现代小麦进化，表观电子传递速率有增大趋势，其受水分胁迫影响的程度在花前期有加剧趋势，花前期栽培一粒、栽培二粒、普通小麦、陕253和长武134这五种小麦在水分胁迫下表观量子产额的降幅分别为5%、7.47%、14.29%、33.3%和53.49%，光饱和Pn的降幅分别为8.8%、26.14%、23.25%、44.22%和51.29%，光饱和点整体上也是下降的，且这三个指标的降幅随进化程度提高有增大趋势，表明小麦在进化过程中能量转换系统受水分胁迫影响的程度加剧；而在水分胁迫下，小麦的羧化效率和RuBP再生速率也均下降，下降的程
