脱硫石膏改良盐碱土对水稻质膜和叶绿素荧光特性的影响
Effects of Improved Saline-alkali Soil by Desulfurized Gypsum on Plasma Membrane and Chlorophyll Fluorescence Characteristics of Rice
摘要
Abstract
In this study,a salt-sensitive rice variety Koshihikari and a salt-tolerant variety Bertone were used as material,three treatments were designed as normal paddy soil,typical saline-alkali soil,modified saline-alkali soil,and rice samples were sampled at 1,4,7,14 days after transplanting to measure rice leaf damage percentage,leaf MDA content,leaf chlorophyll content and chlorophyll fluorescence characteristics, so as to analyze the improvement effects of modified saline-alkali soil. The results showed that as time went by compared with normal paddy soil,the leaf damage percentage and MDA content significantly in-creased, while chlorophyll a,b contents,total chlorophyll content and Fm,Fv/Fm,ETR were significantly reduced in typical saline-alkali soil and modified saline-alkali soil. Compared with typical saline-alkali soil,the leaf damage percentage and MDA content significantly decreased,and chlorophyll a,b contents, total chlorophyll content and Fm,Fv / Fm of these two rice varieties were significantly increased in modi-fied saline-alkali soil, and showed different variation, the salt injury symptom of Bertone was minor. In conclusion, the moderate application of desulfurization gypsum, modifier and organic fertilizer could effectivelyalleviate the harm of saline-alkali soil on rice seedlings,especially for salt-tolerant rice varieties.关键词
