Studies on Allelopathic Effects of Camellia sasanqua on Dichondro repens and Several Plants Seedlings

The laboratory test showed that Camellia sasanqua water extract had a stronger effect on the seed germination of Dichondro repens,Lolium perenne,Festuca elatior,Agrostis matsumurae,Poa annua,Trifllium repens,Cynodon datylon,Raphanus sativu.After treated with 0.02 g/ml of the extract,the seed germination of 8 species was different.The order of sensitivity of eight plants to the Camellia sasanqua extracts was Cynodon datylon Agrostis matsumurae= Poa annua Dichondro repens Lolium perenne= Festuca elatior Trifllium repens Raphanus sativu.The extract of root,stem and flower inhibited the seeds germination of 8 species,but leaves extract hastened seeds germination to 8 species.
