The effect of exogenous chemicals GA, and tryptophane(Trp) on the growth of dry cultivation rice seedlings under the condition of lack of Zn2+ was investigated by means of field tests. The results showed that under the condition of lack of Zn2+, the rice seedlings from dry nursery could not grow well. Spraying the GA, at the concentration of 5mg/L could not ef-fectively improve the seedling quality, but the obvious recovery effect of seedling growth could be obtained by spraying the Trp at the concentration...

The effect of exogenous chemicals GA, and tryptophane(Trp) on the growth of dry cultivation rice seedlings under the condition of lack of Zn2+ was investigated by means of field tests. The results showed that under the condition of lack of Zn2+, the rice seedlings from dry nursery could not grow well. Spraying the GA, at the concentration of 5mg/L could not ef-fectively improve the seedling quality, but the obvious recovery effect of seedling growth could be obtained by spraying the Trp at the concentration of 500mg/L or spraying the mixture of GA, and Trp with respective concentration of 5mg/L and 500mg/L. Also, the increasing effect action could be found through spraying this mixture;Under the condition of rich of Zn2+(fertilizing Zn2+ to the seedling bed), spraying the GA, at the concentration of 5mg/L made the number of tillers and total roots per plant decrease obviously and no effect was observed by spraying the Trp with the concentration of 500mg/L. The re-sults indicated that:①under the condition of lack of Zn2+, the main reason for inhibition of seedling growth was the reducing the synthesis of Trp in plant and the exogenous Trp had a supplemental action. On the premise of spraying Trp, some path-ways regulated by GA3, which affected the metabolism of lAA or Trp, might exist in plant, so the increasing effect action could be gained between GA, and Trp;②under the condition of rich of Zn2+, dynamics equilibrium of endogenous plant hor-mones might be disturbed and normal growth of seedlings was damaged by spraying exogenous GA3, so that the seedling qual-ity was reduced.

在缺Zn2+条件下,旱育稻秧生长不良。喷施质量浓度为5mg/L(赤霉素)GA3不能有效地改善其素质。喷施质量浓度为500mg/L的色氨酸(Trp)或质量浓度为500mg/L的Trp与质量浓度为5mg/L的GA3混喷对秧苗生长有明显的恢复效应,而且混喷具有增效作用。在Zn2+充足(苗床施Zn2+)的条件下,喷施质量浓度为5mg/L的GA3使分蘖数及总根数明显减少;喷施质量浓度为500mg/LTrp效果不明显。以上结果表明:(1)缺Zn2+条件下,秧苗生长受抑的主要原因是植株体内Trp的合成减少,外源Trp可弥补其自身合成的不足,外源GA3可能通过某种途径调节体内IAA或Trp的代谢而使其与Trp混喷具有增效作用;(2)在Zn2+充足条件下,外源GA3可能干扰内源激素间动态平衡而破坏秧苗正常生长,使秧苗素质下降。
