- 摘要:
- 以崇明水仙为试材，采用叶面喷施水杨酸的处理方法，研究了水杨酸对崇明水仙生长的影响。结果表明：水杨酸对崇明水仙有矮化株型、推迟开花及延长花期的作用，其中以600 mg/L处理对株高矮化效果最好，株高较对照降低8.8%，800 mg/L处理对花葶矮化效果最好，花葶较对照降低13.0%。800 mg/L处理对推迟开花的效果最明显，可推迟10 d开花。100 mg/L处理的花期最长，可达29 d，相比对照延长7 d。除此以外，水杨酸处理下的崇明水仙在叶宽、叶厚及花葶数、花葶强度间存在显著性差异。但是，水杨酸喷施对崇明水仙分株数、叶片数、花葶数、花朵数等没有明显影响。
- Abstract:
- Using Narcissus tazetta var.chinensis as material,the effect of salicylic acid (SA)onits growth and plant type and flowering time regulation by spraying SA with different concentrations were studied.The results showed that the plant height of Narcissus tazetta var.chinensis was decreased under SA treatment，flowering time was postponed and the flowering period was extended.The best effect on plant height was observed under SA treatment with 600 mg/L,the plant height was decreased 8.8% by compared with CK，the best effect on stalk height was observed under SA treatment with 800 mg/L，and the stalk height was decreased 13.0% by compared with CK.The most obvious effect on delaying flowering was observed under 800 mg/L SA treatment，which was ten days later by compared with CK.The longest flowering period was observed under 100 mg/L SA treatment，which lasted up to 29 days and extended 7 days by compared with CK.In addition，there was a significant difference in leaf width，leaf thickness，stalk number and stalk strength by spraying SA.However,there was no significant effect on the number of plantlet number，leaf number，stalk number and flower number by spraying SA.
