【摘要】 用硅胶薄板层析和紫外光分析仪检测出冬麦越冬幼苗茎尖和越冬窖藏胡萝卜茎尖内均有类玉米赤霉烯酮物质,其含量及消长情况恰与春化作用的深度同步,这表明类玉米赤霉烯酮与春化作用密切相关。它可能是控制植物通过春化作用的一种物质。更多还原

【Abstract】 It was found that there is a zearalenone-like substance in the growing points of vernalized wheat seedlings and carrot plants. The content of this substance synchronously increased with the depth of vernalization. It was separated by thin layer chromatography. Its UV spectrum was similar to that of zearalenone. It is believed that this substance may be one of the important endogenous substances which control the vernalization of winter plants.更多还原
