甘蓝型油菜花期化学调控研究
A Study on Chemical Regulation of Flowering in Brassica napus
摘要
Abstract
The sightseeing rapeseed has a significant contribution to increasing the potential value of rape-seed.However,the current flowering period of sightseeing type rape is short (about 30 days),which shortens the tourism period. In this experiment able to extend flowering period of Brassica napus, the reagents were screened from 15 kinds of chemical reagents.The selected reagents were combined with each other to obtain a best chemical control method to prolong the flowering period of rapeseed. The results revealed that 2,4-D,in-dole acetic acid and growth retardants could prolong the flowering period of rapeseed for 4 days,5 days and 6 days,respectively,and the effect was the best in the first spraying period (a week before flowering).Moreover, 1× concentration treatment was found better than 3×.However,2,4-D in the later experiments resulted in with-ering of a small amount of rapeseed in individual and combined treatments. Therefore, combination of indole acetic acid+growth retardant agents is the best and it can extend the flowering period of the rape for 6 days without side effects.In this study,the selected indole acetic acid and the combination reagent (indole acetic acid+ growth retardant) had the ability to prolong the flowering period of rapeseed,which offers an important guideline to the chemical regulation of rapeseed.关键词
