摘　　要：对10种海南胡椒属植物叶片进行-3,-5,-7℃低温处理后,采用电导仪法和硫代巴比妥酸法,分别测定低温低温胁迫对海南胡椒属植物叶片的相对电导率和丙二醛含量的影响,同时对其抗寒性进行评价。结果表明:蒌叶、山蒌、大叶蒟、复毛胡椒抗寒性较强,而大叶种胡椒和海南蒟的抗寒能力较弱。In order to evaluate cold resistance of Piper plants in Hainan,relative conductance percentages and malondialdehyde contents of 10 germplasms of Piper plants after treatments of their leaves with low temperature of-3 ℃ ,- 5 ℃ -7 ℃ were measured. Based on the relationship between the relative conductivity and malondi-aldehyde （ MDA） content with the cold resistance,of 10 species of Piper in Hainan,the cold resistance of P. betle,P. sarmentosum,P. laetispicum,and P. bonii are comparatively strong,and that of P. nigrum ＂Lampong Type＂and P. hainanense are weaker.
