按植物性状统计,木本维管束植物有238种,草本植物有300种,藤本植物有80种。
Aim to find the basis in morphology that herbs have hypericin while xylophyta have not hypericin in Hypericum L., and to provide the basis for developing plant resources in Hypericum.目的寻找金丝桃属中,草本植物含金丝桃素而木本不含的形态学及组织化学依据,为该属植物资源的开发利用提供依据。
Results There are secretory nodule and secretory cavity(canal), two secretory structures different in the character of morphology, in herbs, but there is only secretory cavity(canal)in xylophyta.结果存在分泌细胞团和分泌囊(道)二类形态结构特点不同的分泌结构,草本植物中两者都有,而木本植物中只有分泌囊(道)。
