Abstract:
Taking Colocasia esculenta L.Schott var.cormosus CV.Hongyayu in Yanshan Jiangxi as material,the effect of different temperature difference between day and night on the growth and development and physiological and biochemical indexes were studied.The results showed that with the increase of temperature difference between day and night,the plantlet height and root length of Colocasia esculenta L.Schott var.cormosus CV.Hongyayu in Yanshan Jiangxi decreased significantly and the new bud number and new root number did not change significantly;at the same time,with the increase of temperature difference between day and night,the total chlorophyll content,total soluble sugar content and soluble protein content of Colocasia esculenta L.Schott var.cormosus CV.Hongyayu in Yanshan Jiangxi plantlets increased significantly,membrane permeability and MDA content decreased significantly,root activity showed a trend of first decreased and then increased and then decreased.
