葡萄砧木叶片抗寒生理指标的比较研究

The Comparative Study on Cold-Resistance Physiological Index of Grape Rootstock Blade

摘要: 以抗砧3号、3309C、188-08、101-14、5BB、SO4、5C、110-R和贝达等9个葡萄砧木叶片为材料，测定其相对电导率、可溶性糖、可溶性蛋白质、脯氨酸和丙二醛的含量，比较9个葡萄砧木叶片的抗寒生理指标。结果表明抗砧3号相对电导率最低，188-08最高；可溶性糖含量，SO4最高，为2.27%，抗砧3号最低，为0.38%；5BB可溶性蛋白质含量最高，为33.95 mg/g，110-R最低，为1.81 mg/g；脯氨酸含量，5C最高，抗砧3号最低；188-08丙二醛含量最高，贝达最低。综合比较分析，5C、5BB和SO4抗寒性较强于其他砧木品种，且抗寒性5C > 5BB > SO4。

Abstract: Taking nine grape rootstock blades of Fight anvil 3, 3309C, 188-08, 101-14, 5BB, SO4, 5C, 110-R and beida as materials, the relative conductivity, soluble sugar, soluble protein proline and MDA content are estimated. The results showed that relative electric conductivity of Fight anvil 3 was the minimum, 188-08 was the highest; as for Soluble sugar content, SO4 was the highest, about 2.27%, Fight anvil 3 the minimum, for 0.38%; soluble protein content of 5BB was the highest, about 33.95 mg/g, 110-R the lowest, 1.81 mg/g; the content of proline of 5C was supreme, Fight anvil 3 the minimum; content of MDA of 188-08 was the highest, beida the minimum. The comprehensively comparative analysis shows that frost resistances of 5C, 5BB and SO4 were stronger than other varieties of stock, and the frost resistance is 5C > 5BB > SO4.
