摘  要:
为了明确大花金鸡菊不同器官的除草活性,给进一步开展活性化合物的研究提供依据,以生菜、反枝苋、苘麻、小麦和稗草为受体植物,采用琼脂混粉法进行了室内除草活性的测定。结果表明,大花金鸡菊的不同器官粉末在10g.L-1的添加浓度下对各受体植物幼苗的生长均具有明显的抑制作用。对生菜、反枝苋和苘麻3种双子叶植物所表现出的抑制效果要高于对小麦和稗草2种单子叶植物的抑制效果。各器官之间除了对小麦幼苗和反枝苋胚轴的生长表现出明显的抑制差异外,对其余受体植物胚根和胚轴的抑制效果之间多数差异不大。

摘  要:
In order to understand the herbicidal activities of different organs of Coreopsis grandiflora Hogg.and provide the evidence for further study of active compounds,the studies were conducted using seedlings of Lactuca sativa L.,Amaranthus retroflexus L.,Abutilon theophrasti Medicus Malv.,Triticum aestivum L.and Echinochloa crusgalli(L.)Beauv.as the receiver plants by the method of grinded Coreopsis grandiflora Hogg.tissue powder mixed with agar(PPA)in the laboratory.The growth of different receiver plants seedlings were inhibited remarkably by different organs of C.grandiflora Hogg..In addition,the inhibitory effects on three dicotyledon plants were higher than that on two monocotyledon plants.Besides on growth of T.aestivum seedlings and hypocotyls of A.retroflexus L.,the inhibitions were non-obvious different among the organs of C.grandiflora Hogg.on growth of other receiver plants seedlings.
