The Effect of Triacontanol on the Germination of Spore and the Growth of Germling and Frond of Gloiopeltis furcata
摘要
Abstract
Three experiments were conducted to study the influence of triacontanol on the germination of spore ,and growth of germling and frond in Gloiopeltis furcata. In experiment 1, the attachment spores after incubation for 3 d following inoculation were dipped in triacontanol at concentration of 0. 50, 1.00,2. 00 mg- L-1 ,and for 14 or 24 h,respectively. The dipping was repeated at lO-d intervals for 3 times. In experiment 2,1.5-mm long germling was dipped in triacontanol at concentrations of 0. 25,0. 50,1.00 and 2. 00 mg· L-1 ,respectively for 24 h. The treatments were carried out for once or repeated 4 times at 15d intervals, respectively. In experiment 3, the frond was dipped in triacontanol at concentrations of 0. 50,1.00 and 2. 00 mg · L once for 18 or 24 h, respectively. The results revealed that triacontanol had no effect on the mass gain and frond growth, but significantly affected spore germination and germling outshoot ramification. At concentrations of 0. 50 or 1.00 mg · L -1 , triacontanol promoted the spore germinating disc growth and the germinating burgeons, with the best effects achieved by dipping in concentration of 1.00 mg · L-1 for 14 h. Treatment with triacontanol at concentration of 2. 00 mg· L-1 and for 24 h impaired discs growth and survival. Concentrations of 0. 25 -2. 00 mg - L-1 all enhanced the germling outshoot ramification,with better results achieved after 4-time repeated treatment than once single dipping.关键词
