摘要

This study was carried out with a view to inducing the development of pistil type (P-type) or leafyshoot type (L-type) proliferation in the mutant strain of rice plant grown in GA and/or NAA treated soil in summer when spikelet type (S-type) one was more frequently developed than that of the other types. It was observed that during summer time mutant rice plant treated with GA and/or NAA produced more number of P-type and L-type proliferations than the untreated ones whereas the production of S-type proliferation was decreased more than that of the untreated mutants. This meant that during summer production of P-type and L-type proliferations in the mutant rice plant would be possible through the treatment with GA and/or NAA. From the fact mentioned above, it was made obvious that GA and/or NAA, by increasing the auxin contents in the treated mutant, would counteract the influence of summer environment which was responsible for the production of S-type proliferation and would produce favourable environment within the treated mutants for the production of P-type and L-type proliferations which would have been done by winter and early spring environment only. It was also observed that the treated mutant produced more number of adventitious roots at the base of the spikelets than that found in untreated ones. The untreated mutant, producing more number of P-type proliferation and less number of stamens in the spikelets during August to December, reconfirmed the results of the previous study.
