基于干旱胁迫系数对'WL'系列苜蓿品种抗旱性的综合评价
Comprehensive evaluation of drought resistance of'WL'series Medicago sativa varieties based on drought stress coefficient
摘要
Abstract
The experiment aimed to explore the effects of different levels of drought stress on the physiological indicators related to drought resistance of 12 American'WL'series Medicago sativa.Hydroponic method was used to subject 12 American'WL'series Medicago sativa to drought stress treatment,and seven physiological indicators related to drought resistance,including aboveground length,underground length,germination rate,aboveground fresh weight,and underground fresh weight and so on were measured.Combined with principal component analysis,membership function method,and D-value comprehensive evaluation,the drought resistance of different varieties was evaluated.The results showed that when the concentration of PEG-6000 solution was 10%,the top five in the D-value comprehensive ranking were WL343HQ,WL903,WL168HQ,WL319HQ,and WL440HQ.When the concentration of PEG-6000 solution was 20%,the top five in the D-value comprehensive ranking were WL343HQ,WL440HQ,WL319HQ,WL168HQ,and WL354HQ.When the concentration of PEG-6000 solution was 30%,the top five in the D-value comprehensive ranking were WL656HQ,WL343HQ,WL358HQ,WL903,and WL363HQ.The study show that WL343HQ had a better comprehensive performance and is suitable for planting in areas with different levels of drought.关键词
