Abstract
【Objective】The changes of conductivity percentage,malondialdehyde(MDA) content and the activities of superoxide dismutase(SOD) were studied by spraying abscisic acid(ABA) on cotton seedlings in low temperature(5℃).【Method】The variety of China Cotton Research Institute NO.15(CCRI 15) was used as material, to conduct chilling treatment by 0,2,4,6,12,24 and 48 h,72 h,with ABA concentration of 0,10-8,10-7,10-6 and 10-5mol/L.Data were collected to do ANOVA and Duncan multiple comparison using the software Prism 4.【Conclusion】The result showed that both chilling time and ABA concentration could affected conductivity percentage,MDA content and SOD activities significantly.But they had no interaction with each other.When it was treated with ABA 10-7mol/L for 4 h,the conductivities percentage and MDA content decreased ,and SOD activities increased quite significantly.The chilling resistance of three commonly used varieties,CCRI 15,CCRI 35 and Xinluzao8,was compared after pre-chilling treatment for 4 h at 5℃ with ABA 10-7mol/L.The result was the chilling resistance of CCRI15CCRI35Xinluzao8.
