北方粳型超级稻灌浆结实期碳水化合物含量和保护酶活性的变化
Changes in Carbohydrate Content and Protective Enzyme Activity of Japonica Type Super Rice During Grain-Filling Stage in North China
摘要
Abstract
The carbohydrate and malondialdehyde contents and protective enzyme activities in grains and leaves of rice during grain-filling stage were investigated in a pot experiment with typical japonica super rice varieties, Shennong 265 and Shennong 606 as materials and Akihikari and Liaojing 294 as control.The results showed that Shennong 265 and Shennong 606 had significant advantage in yield.Glucose, fructose and sucrose contents in leaves of Shennong 265 were significantly higher than the control Akihikari at 20 days and 40 days after flowering.At 40 days after flowering, starch content in grains of Shennong 265 was also significantly higher than that of the control Akihikari.Shennong 606 showed no significant difference compared with the control Liaojing 294 in carbohydrate contents in grains and leaves during grain-filling stage.Roots displayed early senescence in contrast to aerial parts, which was indicated by earlier peak of protective enzyme activity in roots than in leaves of japonica type super rice.Shennong 265 and Shennong 606 showed delayed senescence because their leaves and roots had low malondialdehyde content, high superoxidase dismutase activity and peroxidase activity compared with the control varieties.关键词
