摘要:设置4,24,44 ℃温度梯度,处理大蓟 (Cirsium souliei)、加拿大飞蓬(Erigeron canadensis L.)、清明菜(Herba Gnaphalii Affinis)、白蒿(Herba Artemisiae Scoparia)、苦荬菜(Ixeris chinesis(Thunb.) Nakal)、马兰(Baphicacanthus cusia)、天名精(Carpesium abrotanoides L.)、黄鹌菜(Youngia japonica (Linn.)DC.)、泥胡菜(Hemistepta lyrata Bunge)和小蓟(Herba Cephalanoploris)等10种菊科杂草,并测定其叶片中丙二醛含量、脯氨酸、可溶性糖和过氧化物酶活性.结果表明:10种菊科杂草对高温耐受能力由大到小分别为马兰、泥胡菜、黄鹌菜、清明菜、小蓟、大蓟、加拿大飞蓬、天名精、白蒿和苦卖菜;对低温耐受能力由大到小分别为天名精、加拿大飞蓬、马兰、白蒿、大蓟、泥胡菜、苦卖菜、小蓟、黄鹌菜和清明菜.

Abstract: Under different artificial temperature,the contents of soluble sugar,proline and malonaldehyde(MDA) as well as activity of POD of 10 Compositae weeds including Cirsium souliei,Erigeron canadensis.L.,Herba Gnaphalii Affinis,Herba Artemisiae Scoparia,Ixeris chinesis(Thunb.)Nakal,Baphicacanthus cusia,Carpesium abrotanoides L.,Youngia japonica (Linn.)DC.,Hemistepta lyrata Bunge and Herba Cephalanoploris are tested under 4 ℃,24 ℃ and 44 ℃ temperature respectively.The MDA changes of ten Compositae weeds indicated that their resistance to high temperature of 44 ℃ ranked as Baphicacanthus cusia,Hemistepta lyrata Bunge,Youngia japonica (Linn.)DC.,Herba Gnaphalii Affinis,Herba Cephalanoploris,Cirsium souliei,Erigeron canadensis.L,Carpesium abrotanoides L.,Herba Artemisiae Scoparia and Ixeris chinesis(Thunb.)Nakal,while those to low temperature of 4 ℃ ranked as Carpesium abrotanoides L.,Erigeron canadensis L.,Baphicacanthus cusia,Herba Artemisiae Scoparia,Cirsium souliei,Hemistepta lyrata Bunge,Ixeris chinesis(Thunb.)Nakal,Herba Cephalanoploris,Youngia japonica (Linn.)DC.and Herba Gnaphalii Affinis.

Key words: compositae weeds, physiological indices, temperature stress
