Abstract:
OBJECTIVEThe aim of the present study is to investigate the effect of low temperature vernalization on metabolism change of carbon and nitrogen of Isatis indigotica.
METHODThe Yunnan and Beijing I. indigotica seedlings with six leaves were vernalized at 4 degrees C for 25 days, and the metabolism indicators of carbon and nitrogen were measured.
RESULTThere appeared a dramatic increase in the soluble sugar content, reducing sugar content and soluble protein content in response to the low temperature, after termination of vernalization it reached the maximum, however, starch and total nitrogen concentration decreased significantly, after termination of vernalization it reached the minimum.
CONCLUSIONThe high C/N value can promote the low temperature vernalization of I. indigotica.
