摘要：

本文研究了温度、继代周期、光照时间和光照强度等培养条件对金叶复叶槭组培苗根、叶及苗高生长的影响，结果表明:温度、继代周期、光照条件对苗高影响较大，差异均达到显著水平；同时发现继代周期显著影响叶片数量、光照时间对根生长系数影响差异达到极显著水平。筛选出在30℃、4200Lx的光照强度下，16h/d光照时间、继代周期35d为金叶复叶槭最佳培养条件。

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.
