不同年份30d短日照处理对地被菊开花的影响
Studied the influence of 30d short-day treatment on flowering of Ground-cover Chrysanthemum between different years
摘要
Abstract
[Objective] Reveal the mechanism of 30d short-day treatment to control the florescence of Chrysanthemum.[Method] The differences of 30d short-day treatment on flower bud differentiation and flowering of Chrysanthemum were compared between different years.[Results] There was a secondary flowering phenomenon in 2014,and the early flowering stage was earlier 43 d than control in first time flowering.Only flowering one in 2015,the flowering was same with control.Plant height and crown were significantly lower than control,but the differences were non-significant in different years.And the flowers amount of 2014 was significantly higher than 2015.The soluble protein contents of 30 df in 2014 were significantly higher than control in visible flower color stage,early flowering stage and full bloom flowing stage;the contents of all flowering stages were significantly higher than control in 2015;the contents were significantly difference in visible flower bud stage,early flowering stage,full bloom flowing stage and later flowering stage between different years.The soluble sugar contents of 2014 were significantly lower than control in visible flower color stage and early flowering stage,and them of 30 df were significantly higher than control in visible flower bud stage and full bloom flowing stage;the contents of 2015 were significantly higher than control in visible flower bud stage and full bloom flowing stage,and lower than control in visible flower color stage and later flowering stage;the soluble sugar contents were significantly difference in different years.Flower bud differentiation started in 2014 earlier 6d than 2015,and earlier 43 d completed flower bud differentiation.[Conclusion] Short-day treatment inhibits the development in plant height and crown,and influences the flower bud differentiation and flowering of Chrysanthemum.30 d short-day is the sensitive period to flower bud differentiation and flowering of Chrysanthemum.When plants grow in a suitable condition,they will complete advanced flower bud differentiation and flowering,if not,they will not induce differentiation or appear flowering reversion.关键词
