Effects of B9 on the growth and flowering of potted Chrysanthemum morifolium “puma”

This study was carred out to investigate the effects of B9 on the growth and flowering of chrysanthemum morifolium “puma”.This experiments showed that B9 markedly suppressed plant height, and the plant height was reduced linely with increasing B9 concentration.In 250 ppm and 350ppm, the stem diameter were increased. In 250 ppm treatmented-plants, the number of leaves greatly increased, but the others was not. All treatments increased total leaf chlorophyll content, while B9 did not influence flower size. Consequently, B9 treatment can be recommended for production of quality flowering plants of C. Morifolium“puma”.
