淹水对不同葡萄砧木生长及光合特性的影响
Effects of Waterlogging on Characteristics of Growth and Photosynthesis in Different Grape Rootstocks
摘要
Abstract
[Objective] The purpose of this study was to elucidate the physiological responses of grape rootstocks to waterlogging stress and compare their tolerances to waterlogging stress.[Method] Seven grape rootstocks varieties were treated with pot waterlogging to study the effects of waterlogging stress on the growth,leaf photosynthetic characteristics and root physiological indexes.Based on the principle component analysis and cluster analysis,the waterlogging-tolerance of these varieties were comprehensively evaluated.[Result] The results showed that shoot growth,total dry matter,root vitality,total root length,total root surface area,chlorophyll content and net photosynthetic rate under waterlogging stress obviously declined compared with the control,shoot growth decreased by 14.01%-34.92% and dry weight decreased by 5.99%-30.79%.The impact on root was more serious than on leaf,showed that the root/shoot ratio decreased,SO4,101-14M,3309C and Beda were less influenced by waterlogging stress,while l103P,140Ru and 110R was more influenced; relative membrane permeability (RMP),proline (Pro) and ADH activities in roots were significantly increased.[Conclusion] SO4,101-14M,3309C and Beda showed higher tolerance to waterlogging stress,while 1103P,140Ru and 11 0R were sensitive to waterlogging stress.关键词
