Effect of B-9 on the Growth and Development of Camellia oleifera

The experiment of spraying different concentration of B9 on the new leaves surfaces of Camellia oleifera′s shoots were carried out,the results showed that:spraying B9 on the leaves surfaces would intensely inhibit the shoots growth, shorten the internode length and increase the number of short shoot;the chlorophyll content,the photosynthesis rate and the protein content of leaves would be increased respectiveTherefore,the leaf′s metabolism of Camellia oleifera willbe promoted
