13种观赏草引种的生物安全性初探
Preliminary study on the biological safety of 13 ornamental grasses species
摘要
Abstract
In order to prevent the ornamental grasses bringing biological disasters for blind promotion,we identified the risk of alien biological invasion of the 13 species of introduced ornamental grasses by analyzing the seeds,adventitious roots and quarantine venereal insects.Meanwhile,the ecological adaptability and safety of the application of these ornamental grasses were also analyzed.The results showed that there was no sowing phenomenon during the experiment period.Meanwhile,we did not observe the phenomenon of root sprouting in a distance of 0.1-1.0 m from the mother plant and the quarantine venereal insects were not detected.Scirpus validus and S.validus cv.zebrinus were the highest resistance species and their correlation degrees with strong resistance variety were 0.763 9.Cortaderia selloana and C.selloana 'Pumila' had a little less resistance than the species mentioned before and their correlation degrees were 0.748 0.The risk of causing fire for planting these ornamental grasses in the landscape was low.All above results proved that planting these 13 introduced ornamental grasses barely existed biological invasion in Ningbo and their application can be promoted in Ningbo and surrounding areas.关键词
