在《植物学》教学中,做光合实验一般用天竺葵作材料。但天竺葵抗寒性差,北方需在室内越冬,一般学校多无温室;叶小,一片叶仅能供一组学生做实验,天竺葵需要量大。为解决这个矛盾,近年我们采用蜀葵作光合实验材料,取得了良好的效果。蜀葵(Althaea rosea),又名熟季花、一丈 In the “botany” teaching, do photosynthesis experiments commonly used geranium as a material. However, geranium cold resistance is poor, the north need to winter indoors, most schools and no greenhouse; leaf small, a leaf only for a group of students to experiment, geranium needs large. In order to solve this contradiction, in recent years we used Hollyhock for photosynthetic experimental materials, and achieved good results. Althaea rosea, also known as mature flowers, a husband
