Abstract:

The effects of temperature,subculture cycle and light on the root,leaf and plantlet height of Acer negundo ‘Aureomarginatum’ in vitro were studied .The results showed that the differences by temperature, subculture cycle, light on the plantlet height reached the significant level, it was significantly affected on leaf number by subculture cycle, and on root growth coefficient by illumination time , The optimal culture conditions for Acer negundo ‘Aureomarginatum’ in vitro were at 30℃, 4200Lx light intensity, 16h / d illumination time, and the subculture cycle was 35d.
