Evaluation on Alkaline Salt Tolerance of Grape F1 Generation Hybrids
摘要
Abstract
We evaluated alkaline salt tolerance in four hybrids of Vitis amurensis cv.‘Zuoshan1'x ‘SO4'(A11,A14,A15,A17) and 2 hybrids of V.amurensis cv.‘Zuoshan1'x ‘101-1'(B24,B26) to assess the physiological response of these hybrids and identify the strains with high alkaline salt tolerance as candidate rootstocks for saline-alkali land.Rootstock 1103P and V.vinifera cv.‘Crimson Seedless' were conducted as double controls.The potted grapevines were irrigated with 100 mmol·L-1 NaHCO3 (pH8.62).Comprehensive assessment was based on principal component analysis and correlation analysis.The plant height,root activity,leaf and plant water content were reduced under NaHCO3 treatment,whereas the electrical conductivity,MDA content,soluble sugar and free proline content were increased.The plant height of A17 was minimally affected.The plant water content was slightly reduced in Crimson,A17 and B24.The difference in root activity of A14 and A15 was not significant,compared with that of their own controls,and the difference in electric conductivity of 1103P,B24,A14,B26,Crimson and A15 was not significant,compared with that of their own controls.MDA content for B26,A17 and A15 did not differ from that of their own controls.Soluble sugar and free proline content of A15 increased the most after NaHCO3 treatment.According to the D value,A14,A15,B24 had strong alkali resistance;Crimson,A11 and A17 had medium alkali resistance;and 1103P and B26 had weak resistance.关键词
