盐胁迫对不同玉米种质资源种子萌发特性的影响
Effects of NaCl Stress on Seed Germination Characteristics of Maize Germplasm Resources
摘要
Abstract
Five NaCl stress concentrations,0,120,180,240,300 mmol/L,were designed to study the effect of NaCl stress on seed germination characteristics of different maize germplasm resources.This study could provide the theoretical basis for appraisal of salt tolerance maize germplasm resources.The results showed that NaCl stress significantly affected the seed germination of 8 maize germplasms.The germination rate,germination energy,germination index,embryo length and embryo weight were significantly inhibited in all of the NaCl concentrations and significantly increased with the increase of NaCl concentration.Luxi 4502 had the best salt tolerance.Luzi 1504,Luzi 1801,H318,M03,C79311 had middle salt tolerance.Luyuan 1423 had the worst salt tolerance.关键词
