植物生长调节剂GA3和B9对长寿花生长发育的影响
Effects of Plant Growth Regulators GA3 and B9 on Growth and Development of Kalanchoe blossfeldiana
摘要
Abstract
Kalanchoe blossfeldiana is an important potted flower, and also is a new variety of cut flowers, which has high eco-nomic value.The leaf surfaces of single-flower K.blossfeldiana variety Mandarin and double-flower K.blossfeldiana variety La Douce were sprayed respectively with different concentrations of plant growth regulators GA3(100, 200, and 300 mg/L) and B9 (2000, 3000, and 4000 mg/L), and the effects of GA3 and B9 on the growth and development of K.blossfeldiana were studied. After being sprayed with GA3, K.blossfeldiana increased in plant height, leaf length and leaf width, and decreased in stem diam-eter, leaf chlorophyll content, duration from field planting to flowering, and flowering duration.The effects of B9 on the growth and development of K.blossfeldiana were reflected as follows:decrease in plant height, increase in duration from field planting to flow-ering, and increase in flowering duration.Moreover, the sensitivities of two K.blossfeldiana varieties to GA3 and B9 were different.关键词
