盐胁迫下不同AMF对棉花生长的影响及其综合效果评价
Effect of different AMF on cotton growth under salt stress and its comprehensive effect evaluation
摘要
Abstract
[Objective]This study aims to evaluate the effects of different arbuscular mycorrhizal fungi(AMF)on cotton growth under salt stress,and screen for AMF strains that promote cotton growth more efficiently under salt stress.[Methods]Using the main varieties of Zhongmian 113 and Tahe 2 in Xinjiang as materials,the effects of inoculation with different AMF on cotton seedling growth,dry matter accumulation,gas-exchange parameters,nitrogen,phosphorus,potassium accumulation,and K/Na ratio were studied.The optimal strain was determined through a comprehensive evaluation method based on entropy weight.[Results]The results showed that AMF inoculation significantly promoted the growth of cotton seedlings under salt stress.Compared with cotton plant without AMF inoculation,the plant height of Zhongmian 113 inoculated with different AMF strain significantly increased by 62.13%-89.55%,the dry matter mass per plant significantly increased by 122.58%-141.94%,the root-shoot ratio decreased by 20.38%-49.34%,the aboveground water content increased by 8.40%-12.65%,and the root water content increased by 9.78%-15.61%;Compared with cotton plant without AMF inoculation,the plant height of Tahe 2 inoculated with different AMF straub was significantly increased by 70.23%-103.88%,the dry matter mass per plant was significantly increased by 80.95%-188.10%,the root shoot ratio was reduced by 42.40%-59.28%,the aboveground water content was increased by 5.88%-11.11%,and the root water content was increased by 12.05%-18.51%.Inoculation of AMF enhanced the absorption of nitrogen,phosphorus and potassium by cotton.Compared with no inoculation,the K/Na ratio in shoots of Zhongmian 113 and Tahe 2 increased by 53.81%-102.96%and 40.54%-122.10%,respectively.The effects of inoculating different AMF showed significant difference.The comprehensive score results showed that the optimal strain of Zhongmian 113 was XJ04B,and the optimal strain of Tahe 2 was XJ02.[Conclusion]Inoculation with different AMF can significantly improve the growth of cotton seedlings under salt stress,and different strains have different performances in promoting cotton growth under salt stress.This experiment provides a reference for screening effective AMF strains in cotton under salt stress environment.关键词
