酸性土壤胁迫下丹波黑大豆和云南小黑豆生理特性研究
Physiological Properties of Soybean(Glycine max)Tamba and Yunnanxiaoheidou under Acid Soil Stress
摘要
Abstract
The acid tolerance mechanism of the soybean was studied using two black soybean( Clycine max) cultivars Tamba and Yunnanxiaoheidou ,bolh of which had significant differences in acid soil tolerance. Soybeans were pot planted in greenhouse with yellow soil(pH 4.55) ,red soil(pH 5.60)and normal soil(pH 7.14). The main physiological indicators of the roots and leaves were measured 50 days later after seedling. The results showed that Tamba grew well in three kinds of soil with nodules while Yunnanxiaokeidou grew badly without nodules in yellow and red soil. Also the enzyme activities of superoxide dismutase (SOD) ,peroxidase(POD)and catalase(CAT)were all increased in roots of both cultivars when grown in yellow and red soil, but the former varied little,which indicated that the reactive oxygen species( ROS)produced from the root were cleavaged by these three enzymes. Meanwhile, the soluble sugars, proline ( Pro), malondialdehyde ( MDA ) , protein carbony ( PC ) and H2 O2 which could form low levels of both osmotic pressure and lipid peroxidation level and then were responsible for their acid stress tolerance, were abundant in the leaves of both soybeans. These results suggest that the acid soil stress tolerance of Tamba is superior to Yunnanxiaoheidou.关键词
