Abstract:
Taking five native ornamental ferns (Polystichum omeiense, Plagiogyria adnata，Bolbitis heteroclite，Pyrrosia calvata and Pteris multifida) collected from Mountain Emei as experimental materials，the effect of four different light treatments including 100%,70%,50%,17% of full sunlight on the growth and ornamental features of them were studied.The results showed that light treatment affected the germination and growth of new fronds of the fern，as the light intensity weakening，the time of new fronds initial germination，most new fronds appearanced and new fronds grow into mature fronds were delayed，and the growth velocity of every tested ornamental ferns slowed down.The light intensity was too strong or too weak both inhibited the growth and reduced the ornamental values of the ferns，while proper shade could promote growth and increased the ornamental values.The responses to light intensity were different in five ornamental ferns，the order for the shade tolerance of them was Pteris multifida>Polystichum omeiense>Bolbitis heteroclita> Plagiogyria adnata>Pyrrosia calvata.
