摘要
在冬季低温条件下,对厚壁毛竹和毛竹的叶、笋、芽3种器官脯氨酸(PRO)、丙二醛(MDA)含量及其超氧化物歧化酶(SOD)、过氧化氢酶(CAT)、过氧化物酶(POD)活性等抗寒生理指标进行了测定和分析。结果表明:厚壁毛竹叶、笋、芽3种器官的脯氨酸(PRO)含量分别为48.73,23.39,48.76 mg/g均高于毛竹,且差异显著;厚壁毛竹的叶、笋、芽3种器官内MDA含量分别为34.98,5.27,4.74 mmol/g(FW)也均高于毛竹,且叶与笋内的含量差异显著;同时,厚壁毛竹3种器官SOD、CAT和POD活性均高于毛竹。最后,隶属函数法综合判定厚壁毛竹抗寒性高于毛竹。
The contents of Proline（PRO）,malonaldehyde（MDA） and the activities of superoxide dismutase（SOD）,peroxidase（POD） and catalase（CAT） in leaves,shoots and buds of Phyllostachys edulis ＇Pachyloen＇ and Ph.edulis were studied in winter.The results showed that the PRO contents in the organs of Ph.edulis ＇Pachyloen＇ were 48.73 mg/g,23.39 mg/g,48.76 mg/g respectively,significantly higher than those of Ph.edulis;MDA contents in the 3 organs of Ph.edulis ＇Pachyloen＇ were 34.98 mmol/g（FW）,5.27 mmol/g（FW）,4.74 mmol/g（FW） respectively,also greater than those of Ph.edulis.The activities of SOD,CAT and POD in the 3 organs of Ph.edulis ＇Pachyloen＇ were also higher than those of Ph.Edulis.Subordinate function values indicated that the cold resistance of Ph.edulis ＇Pachyloen＇ was stronger than that of Ph.edulis.
