[Methods]15 leafy vegetables were selected as test materials in this study. This study investigated the biological characteristics of the 15 ornamental vegetables by introduction trial and grey correlation analysis. In addition,we discussed the application of ornamental vegetables in urban agriculture. [Results]The grey correlation values of 11 ornamental vegetables were greater than 0. 6. The grey correlation values of other four ornamental vegetables were less than 0. 5. Among them,the grey correlation of Beta vulgaris L. var. cicla L. was 0. 94,which have the highest appreciation evaluation. The second appreciation evaluation belonged to rainbow leafy Beta vulgaris L. var. cicla L. with grey correlation of 0. 88. [Conclusions] In short,there are nine ornamental vegetables could be applied in the urban agriculture of Kunming,and there are six ornamental vegetables must be further investigated by cultivation experiment,to understand their cultivation characteristics and key points of management.展开更多

The results showed that Ginkgo biloba and Cinnamomum cassia extracts had significant inhibition effects on B. cinerea mycelium growth( P < 0. 05),with inhibition rates over 70% and EC_(50) values of 0. 027 mg / ml and 0. 039 mg / ml,respectively,significantly different from the antifungal effects of other kinds of medicinal plants; and P. ternata and A. tsaoko extracts showed the second highest inhibition effects,with EC_(50) values of 0. 011 9 and 0. 039 3 mg / ml,respectively. Further experimental application could be carried out.展开更多
