Abstract
To find out the reasons for its indoor low germination rate,the permeability of seed coat,seed anatomical structure,seed vigor and seed endogenesis inhibitors were examined.The results showed that the permeability of seed coat was poor.Chipped seeds reached the highest value of water absorption in less than 38 h as the intact seeds.The proportion of empty seeds was as high as 30%.Seed vigor was low and averaged at 35%.The germinability,shoot and root growth of cabbage seeds were significantly inhibited by methanol extracts of M.boisiana seeds.When methanol extracts of seeds reached a concentration of 25 mg/mL,germination and growth of cabbage seeds were seriously inhibited,suggesting rather high content of endogenesis inhibitors in M.boisiana seeds.Low germination rate of M.boisiana seeds indicated that seed's generation of a new plant was not the main reason for the outburst overspread disaster in the recent years,and the key factors should be further researched.
