12个葡萄砧木品种枝条抗寒性综合评价
Comprehensive Evaluation of Cold Resistance of 12 Grape Rootstock Cultivars Branches
摘要
Abstract
In order to provide scientific basis for the introduction of excellent cold-resistant rootstocks in Gansu,the branches of 12 grape rootstock varieties treated with artificial simulated low temperature were used as test materials,and the relative conductivity,proline,malondialdehyde,soluble sugar and soluble protein contents of the branches were determined.The relative conductivity combined with the Logistic equation was used to predict the half-lethal temperature(LT50)of each variety,and the subordinate function method was applied to make a comprehensive evaluation of the cold resistance of grape rootstocks.The results showed that the relative conductivity,soluble protein,soluble sugar,malondialdehyde,and free proline contents of the branches of each grape rootstock increased gradually,and the calculated half-lethal temperatures(LT50)ranged from-16.32℃to-24.84℃;and the results of the comprehensive evaluation showed that the strengths of cold resistance of 12 grape varieties rootstocks were in the order of Beda,Shanhe 2,101-14,5BB,188-08,SO4,Valliant,3309,1103P,Du Lot,BRNo.2,110R.关键词
