Abstract:
OBJECTIVETo study the change of the activity of protective enzyme to avoid sprout tumble of Pinellia ternata.
METHODA high temperature stress was given to P. ternata. Then the activity of protective enzyme (SOD, POD and CAT) and the content of membrane lipid peroxidation (MDA) were detected after different treating days.
RESULT AND CONCLUSIONBy stress time increasing, the content of MDA in lamina and petiole increased obviously, but it increased invisibly in tuber. After high temperature stress, the activity of both SOD and CAT decreased gradually. The activity of POD increased at first but then decreased rapidly.
