选择6个不同有核葡萄品种(中国野生山葡萄,玫瑰香,巨峰,藤稔,红地球,北醇)的一年生休眠期枝条为试验材料,经过不同温度(-40℃,-20℃,0℃,5℃,25℃)处理12 h后测定葡萄枝条的电解质渗出率和脯氨酸含量变化,判断抗寒性强弱。结果表明:随着处理温度的降低,电解质渗出率增大。与山葡萄相比,藤稔的抗寒性较强,玫瑰香和红地球的抗寒性较弱,巨峰和北醇的抗寒性居中,脯氨酸含量的变化趋势和变化幅度因品种的不同而不同。
The perennial annual dormancy shoots of six different korean grape varieties (Chinese wild grapevine, rose incense, Kyoho, Fujiminori, red globe and northern alcohol) were selected as test materials and tested at different temperatures (-40 ℃, -20 ℃, 0 ℃ , 5 ℃, 25 ℃) for 12 h, the electrolyte exudation rate and proline content of grape shoots were measured to determine the strength of cold resistance. The results showed that the electrolyte leakage increased with the decrease of the treatment temperature. Compared with the grapevine, grapefruit is more resistant to cold, rose and red globe cold resistance is weak, Kyoho and North alcohol center of the cold resistance, proline content trends and the extent of change due to different varieties And different.
