摘要: 目的】研究低温处理对沙棘品种抗寒性的影响,筛选出抗寒能力强品种,为新疆沙棘栽培品种的选择与种植提供可靠依据。【方法】以新疆青河县4个沙棘品种辽阜、阿尔泰新闻、楚依、阿列伊的一年生枝条为材料,分析10 ~-40℃ 条件下沙棘枝条自由水/束缚水比值、电导率、丙二醛含量、可溶性糖和可溶性蛋白含量的变化。【结果】在-20℃以下,4个品种沙棘枝条中自由水/束缚水比值、电导率和丙二醛的含量随着温度的降低逐渐增加,可溶性糖和可溶性蛋白的含量随着温度的降低呈先增加后降低的趋势。在整个低温变化过程中,阿尔泰新闻和楚依品种沙棘枝条自由水/束缚水比值,电导率和丙二醛含量相对较低。【结论】阿尔泰新闻沙棘品种的抗寒性最好,依此是楚依、辽阜和阿列伊,阿尔泰新闻更适宜新疆寒冷地区种植。

Abstract: Objective】 To investigate the effects of low temperature treatment on the cold resistance of four Hippophae rhamnoides L. varieties and select the varieties with strong cold resistance in the hope of providing a reliable basis for the selection and planting of seabuckthorn cultivars in Xinjiang. 【Method】 The yearly branch of four Hippophae rhamnoides L. varieties (Liaojing, Altai News, Chuyi, Alei) in Qinghe County of Xinjiang were used as the testing materials to study the changes of free water/bound water ratio, conductivity, malondialdehyde content, soluble sugar and soluble protein content of Hippophae rhamnoides L. shoots at 10 - -40℃.【Result】Under the temperature of -20℃, the free water/bound water ratio, conductivity and malondialdehyde content of the four Hippophae rhamnoides L. branches increased with the decrease of temperature, and the content of soluble sugar and soluble protein decreased, and then increased with temperature. The free water/bound water ratio, conductivity and MDA content of Altai News and Chuyi Hippophae rhamnoides L. branches were relatively low throughout the process of low temperature change. 【Conclusion】 Altai News Hippophae rhamnoides L. had the best cold resistance, followed by Chuyi, Liaoyu and Aleyi, indicating Altai News was more suitable for planting in cold regions of Xinjiang.

Key words: Hippophae rhamnoides L.; low temperature; cold resistance; electrical conductivity; malondialdehyde
