QI Gui-lin,CHEN Ping,ZHONG Wei-ji(School of Agriculture and Gardening,Zhongkai University of Agriculture and Technology,Guangzhou 510225,China)  
Effects of extracting solution from Hemarthria altissima,Ageratum conyzoides and Zoysia matrella on seed germination and seedling growth of Cajanus cajan(cultivar No.3,No.4)and Merremia hederaceawere studied through germination tests.The results showed that the extracting solution from Hemarthria altissima dropped the seed germination rates of Cajanus cajan(cultivar No.3,No.4)and Merremia hederacea and inhibited seedlings growth in general.The extracting solution from Ageratum conyzoides significantly decreased the seed germination rate and seedling growth of Merremia hederacea and Cajanus cajan cultivar No.3,and its high concentrated solution showed inhibition effect to Cajanus cajan(cultivar No.4).The extracting solution from Zoysia matrella slightly showed the inhibition effect to Merremia hederacea and Cajanus cajan(cultivar No.3) in general,but it decreased the seedling fresh weight of Cajanus cajan(cultivar No.4) significantly.
