| 摘 要： | 以新疆地区的梭梭Haloxylon ammodendron叶片为研究对象,从2003年5月至8月,每隔15 d对梭梭叶片内激素进行测定,研究其内源激素在自然干旱胁迫下的季节动态.结果表明,自然干旱胁迫条件下,梭梭叶片内赤霉素(GA)质量分数表现为波浪式下降的态势;在生长前期叶片脱落酸(ABA)质量分数甚微,盛夏期间,ABA迅速积累,生长后期ABA急剧积累为生长发育过程的最高质量分数;梭梭叶片内吲哚乙酸(IAA)的质量分数在整个生长季表现为下降的趋势;细胞分裂素(CK)的质量分数变化趋势与IAA质量分数动态变化规律类似;梭梭叶片内的CK/ABA的比值一直呈下降趋势.表1参14

| Abstract: | The contents of hormones in the leaves of Haloxylon ammodendron in Xinjiang Uygur Autonomous Region of China were tested every 15 days through May to August to study the seasonal change of endogenetic hormones under natural drought stress. The results showed that content of GA dropped fiuctuantly. In the early growing period, content of ABA was very small, but it accumulated quickly in summer, and it reached the highest level in the late growing period. Content of IAA decreased in the whole growing period. The change of CK content was similar to that of IAA. The ratio of CK and ABA kept on decreasing. Ch, 1 tab. 14 ref. ] |
