耐盐鉴定基质对棉花种子萌发的影响
Effects of Testing Substrates on Cotton Seed Germination in Identification of Salt Tolerance
摘要
Abstract
[ Objective ] The research aimed to provide the theoretical basis for the identification and evaluation of salt-tolerant resource,adaptation screening of salt-tolerant cotton, salt-tolerance breeding and caltivation of cotton. [ Method ] Seed germination of two cotton breeds was tested in six different salt concentration treatments and three different testing substrates,such as underground salty water,NaC1 solution and saline-alkali soil.The influences of salt stress on cotton germination percentage were analyzed. [ Result ] Cotton germination percentage was higher in NaCl solution han that of other two ground-substances. Germination percentages of underground salty water solution treatment and saline-alkali soil condition were close. The suitable density was 0.50％ using NaC1 single salt tolerance, and the suitable density was 0.40％ using underground salty water and saline-alkali soil in identification of salt tolerance. [ Conclusion ] Using underground salty water as the testing substrate in cotton salinity tolerance appraisal was close to actual production.关键词
