摘　要：

百合品种‘ 精粹’ 的鳞茎周径和鲜重随着叶面喷施水杨酸(SA)的浓度的增加而增加; 品种‘ 普瑞头’ 鳞茎周径和鲜重也随着叶面喷施SA的浓度的变化而变化, 其中以0.5 mmol·L-1 SA的效应最明显。叶面喷施SA的百合鳞茎中ABA和GA3含量下降, IAA和ZR 含量上升, 鳞茎中(IAA+GA3)/ABA、IAA/GA3 比值均比未喷施SA 的高, 而IAA/ZR、GA3/ZR 比值则比未喷施SA的低。显示鳞茎膨大与内源激素的含量相关。

Abstract:

Foliar spraying with salicylic acid (SA), the diameter and weight of bulb in lily (Lilium Asiatic hybrids)‘Elite’ increased with the raising of SA concentration, the diameter and weight of bulb in Lilium Asiatic hybrids ‘Prato’ varied with the raising of SA concentration. The effect of 0.5 mmol·L^-1 treatment was the prominentest in all of SA treatments. Foliar spraying with appropriate SA decreased endogenous ABA and GA₃ contents in the bulbs, but endogenous ZR and IAA contents in the bulbs increased. SA increased the ratio of IAA to GA₃ and the sum of IAA and GA₃ to ABA in the bulbs, but decreased the ratio of IAA to ZR, and GA₃ to ZR. The results suggested the bulb development was correlated with endogenous hormone concents.
