【Abstract】 Super sweet corn seeds were soaked in solution of brassinolide for 24 hours at the lower temperature (18±1℃), the activity of amylase in the seeds and the content of soluable sugar and the activity of roots of the seedlings were growth obviously. So the rate of germination was increased, the growth of the seedlings was promoted, the length of the second leaf and the heighr and the dryweight of the seedlings were higher than the CK group.更多还原
