摘要/Abstract

摘要： 本文借助光学显微镜和扫描电镜,对我国西北地区萱草属6种1变种的花粉形态进行了比较研究,不同的种类,其花粉形态或多或少有所不同,说明花粉形态在种间具有分类意义,而且6种、1变种可自然地分为两大类群,第一类群包括小黄花菜、北萱草、黄花菜,第二类群包括北黄花菜、折叶萱草、萱草、重瓣萱草。#br#北黄花菜、小黄花菜的花粉形态差别较大,证明把小黄花菜做为北黄花菜的变种是不妥当的。

Abstract: Pollen grains of 6 species and 1 variety of Hemerocallis were examined by LM and SEM. Pollen morphology is more or less different for each species. It shows interspecific pollen morphology of Hemerocallis in Nor-thwest is significant for classification. By making a study of them, 6 species and 1 variety can be divided naturally into two groups. The first group consists of Hemerecallis minor Mill., H. esculenta Koidz. and H. ci-trina Baroni. The second one includes H. plicala Stapf, H. fulva (L.) L., H. fulva var. kwanso Regel and H. lilio-asphodelus L. emend. Hyland.#br#There is the difference for pollen morphology of H. minor and H. lilio-asphodelus. Evidence shows it is improper that H. minor was designated as a variety of H. lilio-asphodelus.
