Evaluation of Drought Resistance of Main Wheat Varieties in Shandong Province During Germination Under Drought Stress
摘要
Abstract
To clarify the drought resistance of the main wheat varieties cultivated in Shandong Province and to screen out wheat varieties suitable for dryland cultivation,this study used eight varieties,such as'Jimai 60',as test subjects.Drought stress was simulated using 20%PEG-6000,and changes in various indicators during the germination period were measured.The membership function method was employed to comprehensively evaluate the relative coleoptile length,relative plumule length,relative radicle length,relative germination rate,relative germination potential,and stress germination index.The results showed that drought stress not only reduced the germination rate of wheat seeds but also inhibited the growth of the plumule,coleoptile,and radicle.The D values of the eight varieties were ranked as follows:'Jimai 60'>'Linmai 9'>'Yannong 999'>'Shannong 30'>'Shannong 28'>'Luyuan 502'>'Yannong 1212'>'Jimai 22'.Based on the D values,the eight main wheat varieties were classified into three categories:highly drought-resistant varieties were'Linmai 9'and'Jimai 60';moderately drought-resistant varieties were'Yannong 999'and'Shannong 30';other varieties were sensitive.'Linmai 9'and'Jimai 60'are recommended as suitable varieties for dryland cultivation in Shandong Province.关键词
