CHA, Jong Whan (Dept. of Biology, Coll. of Education, Seoul National Univ.) Effect of Gibberelline on the growth and internal components of selected vegetable plants. Kor. Jour. Bot. V(3):11-20, 1962.
The effect of GA on the growth as well as on the internal components of the leaves of ordinary vegetable plants under the soil culture was investigated. A relatively small difference in GA concentration applied showed a marked influence on the growth and constituents of the plants observed. The increase of growth was related to a highly significaat digree with the intensity of GA. Chlorophyll and carotene content in the leaves were significantly with increasing concentration of GA, except for some plants. The growth in all examined plants did not correspond to the contents of chlorophyll and carotene. In contrast the ascorbic acid in the leaves treated with GA detreased in proportion to the GA concentrations. Chlorophyll and ascorbic acid values differed greatly during the two experiments and the difference was proved significant. Carotene content varied with chlorophyll although the ratio of chlorophyll to carotene was not so high as that obtained by Beck and Redman^(3))
