| 摘 要： | [目的]研究ABA对Cd胁迫下水稻根系生长发育的调节。[方法]以中花11号水稻为材料,分析在Cd、Cd＋ABA和Cd＋ABA抑制剂复合处理条件下,水稻根系生长发育的变化。[结果]外源ABA缩短了水稻初生根以及不定根的长度,且明显抑制了初生根和不定根上侧根的形成,ABA也明显缩短了根毛到根尖的距离,但对不定根的数量影响不大。[结论]ABA参与了Cd胁迫下水稻根系生长发育的调节。

| Abstract: | [Objective] The regulation of ABA on rice root system growth under Cd stress was studied.[Method] Taking rice Zhonghua No.11 as material,changes in rice root system growth were studied under the treatments of Cd,Cd ＋ ABA and Cd ＋ ABA inhibitor.[Result] Exogenous ABA could shorten the length of primary roots and adventitious roots of rice and could obviously inhibit the formation of lateral roots in primary roots and adventitious roots;ABA could obviously shorten the distance from root hair to root tip,but had little effect on the quantity of adventitious roots.[Conclusion] ABA takes part in the regulation in rice root system growth under Cd stress. |
