Abstract:
OBJECTIVETo reveal the relation between endogenous hormones and the flower bud differentiation in Schisandga chinensis.
METHODTop buds of extremely short branch and axillary buds of long branch in the same plant of S. chinensis were used as material and the contents of endogenous hormones were measured during different periods of the flower bud differentiation with HPLC.
RESULTThe result showed that flower bud differentiation and the formation of female flower were inhibited by high concentration of GA3 and were promoted by high concentration of ABA or ZT. Low ratio of GA3/ABA has the same result.
CONCLUSIONThere was a correlation between endogenous hormones and the flower bud differentiation of S. chinensis.
