不同盐分胁迫对小麦种子萌发的影响
摘要
Abstract
In order to explore the salt tolerance of different wheat varieties during germination,five wheat varieties with wide extension area in Qingdao were selected and five concentration gradients of NaCl solution were set up to simulate salt stress.The germination index,root length,bud length and fresh weight of wheat seeds during germination were compared comprehensively.The results showed that some wheat varieties had certain adaptability to low salt stress(＜100 mmol·L-1).Low salt stress could increase the germination rate of some varieties,and high concentration salt stress could strongly inhibit the germination and growth of wheat seeds.Germination energy,germination rate,germination index,maximum root length,bud length,root fresh weight and bud fresh weight were significantly negatively correlated with salt concentration,which can be used as the identification index of salt tolerance of wheat during germination.The NaCl concentration of 150～200 mmol·L-1 is suitable for the identification of salt tolerance during wheat seed germination.Among the five wheat varieties,Bangmai Wheat 122 had strong salt tolerance,and Jimai Wheat 22 was the worst.The results can provide a basis for selecting wheat varieties suitable for planting in saline land.关键词
