五叶地锦低温处理条件下与抗寒相关的部分生理生化指标的变化规律
Changing Regularity of Partial Cold-resistance Physiological and Biochemical Indexes of Parthenocissus quinquefolia with Temperature Dropping
【摘要】 研究了五叶地锦与抗寒有关的若干生理生化指标在温度从 - 15℃到 - 38℃逐渐降低处理条件下的动态变化规律。自然越冬五叶地锦当年生枝和 1年生幼苗不同季节中 (后者只在秋季 )枝条基部芽的过氧化物酶活性等的变化 ,为深入研究试材的抗寒能力提供了理论和实践依据
【Abstract】 The dynamic changing regularity of some physiological and biochemical indexes related with cold-resistance was studied with temperature dropping from -15℃ to -38℃. Meanwhile the changes of peroxide enzyme activity of shoots and buds for annual branches and one-year-old seedlings surviving winter successfully were also determined. This paper would provide theoretical foundation for researching this material’s cold-resistence capacity deeply.
