外源6-BA对小苍兰'Red Lion'生长及花期调控的影响
Effect of Exogenous 6-BA on Growth and Florescence Regulation of Freesia'Red Lion'
摘要
Abstract
This experiment was conducted to study the effects of spraying different concentrations of 6-BA(25,50,100 and 200 mg/L)on growth,physiological and biochemical characteristics and flowering period of freesia with the variety'Red Lion'as material.It was expected to provide technical supports for freesia's flowering period control and cut flower cultivation.The results showed that spraying appropriate concentrations of 6-BA was beneficial to prolonging the flowering period of freesia'Red Lion',and the concentration of 6-BA at 200 mg/L significantly increased the flower diameter,scape length,number of florets,plant height and number of leaves.Compared with the control,the flowering period was prolonged by 11 days,the flower diam-eter and the number of florets increased by 50.60%and 114.81%respectively,and the soluble protein content and the POD and CAT activities of leaves increased by 5.00%,97.26%and 393.24%,respectively.In con-clusion,spraying appropriate concentrations of 6-BA could significantly improve the flower quality and quantity of freesia'Red Lion'and prolong the flowering period,and 200 mg/L 6-BA treatment had the best effect.关键词
