采用人工模拟低温环境的方法,以漾泡、大麻1号和大麻2号3个核桃品种的2年生离体叶片为试材,测定不同温度下其相对电导率、丙二醛、可溶性糖和脯氨酸等抗寒生理生化指标。结果表明：随着处理温度的降低,3个品种核桃的相对电导率逐渐升高,丙二醛和可溶性糖含量则呈现“升高-降低-升高”的变化规律,脯氨酸含量分别呈“升高-降低”的变化规律。综合4个抗寒生理生化指标,大麻1号和大麻2号的抗寒能力强于漾泡核桃。
採用人工模擬低溫環境的方法,以漾泡、大痳1號和大痳2號3箇覈桃品種的2年生離體葉片為試材,測定不同溫度下其相對電導率、丙二醛、可溶性糖和脯氨痠等抗寒生理生化指標。結果錶明：隨著處理溫度的降低,3箇品種覈桃的相對電導率逐漸升高,丙二醛和可溶性糖含量則呈現“升高-降低-升高”的變化規律,脯氨痠含量分彆呈“升高-降低”的變化規律。綜閤4箇抗寒生理生化指標,大痳1號和大痳2號的抗寒能力彊于漾泡覈桃。

With two-year isolated branches and leaves as test materials of 3 walnut varieties of “Yangpao”,“Dama 1”and “Dama 2”,the artificial low temperature treatment was used to measure and analyze cold-resistant physiological and biochemical indexes of relative electrical conductivity rate,MDA,soluble sugar and proline of the branches and leaves under different low temperatures.The results showed that,along with reduction of tem-perature,the relative electrical conductivity rate of branches of the 3 walnut varieties increased gradually;the MDA content and soluble sugar content of the three walnuts leaves increased firstly,then decreased and increased again;the proline content increased firstly and then decreased.On the whole,the cold resistance of “Dama 1”and “Dama 2”was better than that of “Yangpao”.
