【摘要】 分株繁殖是凤梨科植物繁殖的重要手段。不同分株时期对观赏凤梨Tillandsia ionantha的影响实验结果表明,子株为母株的1/3高度时进行分株,对母株无显著影响,且子株的生长量最大。分别用激素IAA、BA、GA3喷施,GA350 mg/L的净重增加量最高,达1.503 4 g。BA50 mg/L繁殖系数最高,达12。更多还原

【Abstract】 Division propagation is the important propagation method of Bromeliceae.Through the test about different ramet period for T.ionantha,it’s show that when the height of ramet was about one third of ortet,the growth of ramet was the highest.Sprayed with IAA,BA,GA3 separately,the net weight amount was the highest and increased by 1.503 4 g when spraied by GA3 50 mg/L.Propagation coefficient was the highest,reached 12 by spraying 50 mg/L of BA.更多还原
