槲蕨配子体发育影响因素的初步研究

Primary Study on Effect Factors for Gametophyte Development of Drynaria fortunei

摘要: 主要研究了光照、温度、激素和pH值对槲蕨配子体发育的影响。结果表明:光照强度为2 500~3 500 lx、温度为25℃以及pH值为7.0~7.5时最适于槲蕨配子体的生长发育;激素6-BA和NAA浓度为0.5~1.0 m g/L时有利于槲蕨配子体的增殖和增长。

Abstract: Effect of the illumination,temperature,hormone and pH was studied on gametophyte development of Drynaria fortunei.The results indicated that the optimum illumination and temperature were respectively 2500-3500 lx and 25℃,the pH was 7.0-7.5.the hormone 6-BA and NAA could accelerate the growth of gametophyte and the 0.5-1.0 mg/mL concentration was superior.
