Research on AMF Regulation of Cotton Growth and Ion Balance Under Salt Alkali Stress
摘要
Abstract
To investigate the effects of arbuscular mycorrhizal fungi(AMF)on ion absorption and movement of cotton seedlings under salt and alkali stress,the pot experiment was conducted.'Xinluzao 45'was as material to inoculate Funneliformis mosseae,and the control was not inoculated AMF.The seedlings of 3-leaves were treated by salt and alkali stress with 0,50,100,150,200 mmol·L-1,and the changes of seedling growth and ion content under different treatments were analyzed.The results showed that,with the increase of salt and alkali stress,the root infection rate of cotton decreased gradually and the mycorrhizal dependence increased.With the increase of salinity and alkali stress,the biomass of cotton seedlings decreased gradually,and AMF inoculation could significantly promote the growth and development of cotton.Under various salt and alkali stress treatments,AMF inoculation significantly increased the biomass of cotton seedlings.The contents of Na+and Na+/K+,Na+/Ca2+,Na+/Mg2+in organs of cotton seedlings were significantly decreased,and the contents of K+,Ca2+,Mg2+in organs of cotton seedlings were significantly increased.The transport of Na+from underground to surface was decreased,while the transport of K+,Ca2+and Mg2+from underground to surface was increased.In conclusion,salt and alkali stress could inhibit the transport of K+,Ca2+and Mg2+from underground to above-ground.Inoculation with AMF inhibited the uptake and upward transport of Na+by cotton roots,and promoted the uptake and upward transport of K+,Ca2+and Mg2+by cotton roots.Thus,Na+/K+,Na+/Ca2+,Na+/Mg2+could be reduced,the damage of Na+to cotton plants could be alleviated,and the growth and development of cotton seedlings can be promoted.关键词
