摘要

Effects of tannic acid on GA3-induced growth were studied using 'Ginbozu', a normal and 'Tan-ginbozu', a dwarf rice cultivars. Tannic acid inhibited the GA3-induced growth of the second leaf sheath of 'Tan-ginbozu' though it did not inhibit their endogenous growth. It also showed no effect on the endogenous growth of the second leaf sheath in 'Ginbozu' with the range of the concentrations from 1 to 1000 ppm. Moreover, tannic acid treatment at panicle initiation stage reduced the GA3-induced increase of the plant height and internode length in 'Tan-ginbozu'. Their endogenous growth, however, was not affected with tannic acid in 'Ginbozu' as well as in 'Tan-ginbozu'. From the results obtained, it may be suggested that tannic acid may compete with GA3 in the process of absorption and translocation of exogenous GA3 or conjugation of GA3 into the site of action in plant tissues.
