不同pH值对甘蔗幼苗生长和生理特性的影响
Effects of different pH values on growth and physiological characteristics of sugarcane seedlings
摘要
Abstract
[Objective]The present study was conducted to find out the effects of different pH values on growth and physiological characteristics of sugarcane seedlings, and to provide scientific basis for breeding and production of sugarcane. [Method]The plants of two sugarcane varieties GT21 and ROC22 were grown in nutrient culture. The total chlorophylls, soluble sugar, total protein, malondealdehyde (MDA)and proline contents, and relative conductivity in leaves were determined. [Result]The growth and development of sugarcane plants were not affected significantly between pH 4.57.5, however, the plants grew best at pH 6.0, and showed highest plant height, chlorophyll content, soluble sugar and total protein contents in both varieties, while the relative conductivity, and MDA and praline contents were the lowest,which showed a high coordination of physiological metabolism in sugarcane plants. [Conclusion] Results indicated that the best pH value for the sugarcane plants growth was 6.0.关键词
