7个饲用大豆品种苗期耐盐性评价
Comprehensive Evaluation of Salt Tolerance at Seedling Stage of 7 Hybrid Forage Soybean Cultivars
摘要
Abstract
Salt stress is a major abiotic stress limiting sustainable agricultural development.Screening and identifying salt-tolerant forage soybean varieties is crucial for enhancing high-protein forage yield and utilizing saline-alkali land in China.In this study,seven forage soybean cultivars(S001-S007)were evaluated,with wild soybean(GS)and cultivated soybean Williams 82(W82)used as controls.Under 150 mmol/L and 200 mmol/L NaCl stress,emergence indicators(emergence rate,emergence potential,and emergence index)and seedling morphological traits(plant height,leaf area,root length,and shoot and root fresh/dry weights)were measured.The salt tolerance at the seedling stage was comprehensively evaluated using the membership function method and cluster analysis.The results showed that all evaluated indicators decreased significantly with increasing salt concentrations,and distinct differences in salt tolerance were observed among the varieties.The membership function analysis ranked the salt tolerance of the nine soy-bean varieties from high to low as follows:S007>S002>S003>S004>S005>W82>S001>S006>GS.Furthermore,cluster analysis categorized the nine varieties into three groups:highly salt-tolerant(S002,S003,and S007),moderately salt-tolerant(S004),and salt-sensitive(GS,W82,S001,S005,and S006).关键词
