黄淮海地区主栽大豆品种抗旱性比较
Comparative Study on Drought Resistance of Main Soybean Cultivars Planted in Huang-Huai-Hai Valley Region
摘要
Abstract
Eight soybean cuhivars planted in Huang-Huai-Hai Valley region were selected for the experiment,and their drought resistance was evaluated at seedling,flowering and the whole growth stages.The results showed that there were certain influences on soybean growth when drought at seedling,flowering and the whole growth stages.The total length and surface area of roots were mainly affected by drought at seedling stage,the traits including stem thickness and growth period were affected by drought at flowering stage,and the plant height,root and yield traits were affected by the whole growth stage drought.Among all the cultivars in the experiment,Xudou 14 had better performance in drought resistance during the three stages,so it was a comprehensively drought-resistant variety;Jidou 17 had better drought resistance during the seedling and flowering stages,and Qihuang 34 had better drought resistance in the whole growth stage.关键词
