Effects of Environment Factors on Spores Culture of Hemionitis arifolia Moore

Abstract:

In order to understand the influence of environment factors on culture of Hemionitis arifolia Moore., the effects of temperature, light condition, pH and density on sexual reproduction of spores were studied by micro culture. The results showed that the germination of H. arifolia spores need light, the optimum condition for spore germination and gametophyte development of H. arifolia was under 25℃, 150 μmol m^-2s^-1 of light intensity, pH=6.5 with sowing density of 5-8 grains cm^-2. The management of seedlings was simple. The survival of H. arifolia was high with few disease and insect pest. So, these would provide the technical assistance and theoretical foundation for protection and development of H. arifolia resources.
