硅对果蔗组培腋芽苗增殖生长及相关指标的影响
Effects of Silicon on Proliferation, Growth and Relevant Parameters of in vitro Cultured Fruit Sugarcane Axillary Bud Seedlings
摘要
Abstract
In order to find the effects of silicon (Si) with different concentrations on the proliferation,growth and relevant parameters of in vitro cultured fruit sugarcane axillary bud seedlings (ABS),Si was added into MS medium used for ABS clonal propagation.The results showed that the propagation rate,average net growth,green plantlet period and chlorophyll content all expressed an increasing trend as Si concentration increased in the range of 0～0.70 mmol/L.After Si concentration increased to 0.88 mmol/L,the parameters expressed a significant reducing trend except for the green plantlet period.The propagation rate,average net growth,green plantlet period,chlorophyll content and soluble sugar content of treatment with 0.70 mmol/L Si increased by 38.9％,27.7％,86.7％,119.3％ and 67.5％ over the control,respectively.There were statistically significant differences (p＜0.01) in all parameters between the treatment and the control.It indicated that great effects of Si with suitable content (0.70 mmol/L) in MS liquid medium on increasing propagation rate and reducing cost of ABS production in vitro.关键词
