摘要:

 本文对我国伞形科8属22种和1变种的花粉,除用光学显微镜进行了系统 的观察外,并用扫描电子显微镜观察了它们外壁的细微结构,在综合分析对比的基础上,论证了花粉形态研究在伞形科分属水平上的意义。

Abstract:

This paper deals with the studies of pollen morphology of 8 genera including 22
 species and 1 variety of Umbelliferae (Apiaceae).  They have been investigated under
 both the light microscope and the SEM.  These genera can be distinguished by their
 pollen characters.  The observed data listing in the following table reveal that they
 can be distinguished according to shape of pollen, form of pores, sculpture of exine
and size of grains etc.
  1.  Shape of pollen grains
         (1)  subrhomboidal type:  Chuanminshen Sheh  et  Shan,  Changium  Wolff,
                Cyclorhiza Sheh et Shan
         (2)  oval type:  Seseli L.
         (3)  subrectangular type
                a.  thickened at the equator and rugulose:  Peuecdanum L.
                b.  constricted at the equator and rugulose:  Ligusticum L.
                e.  constricted at the equator and rugulose, thickened at both polar zones:
                     Vicatia DC.
         (4)  equatorially-constricted type, rugulose at the equator, thickened at both
                polar zones: Ferula L.
      2.  Form of aperture
         (1)  rectangular protrude type:  Chuanminshen  Sheh  et  Shan,  Ferula  L.,
                Changium Wolff
         (2)  circular type:  Ligusticum L.
         (3)  elliptic type:  Peucedanum L., Vicatia DC., Seseli L.
      3.  Sculpture of exine
         (1)  reticulate:  Chuanminshen Sheh et Shah
         (2)  pitted-reticulate: Changium Wolff
         (3)  striate-reticulate:  Ferula L., Peucedanum L., Ligusticum L., Seseli L.,
               Vicatia DC.
         (4)  cerebro-reticulate:  Cyclorhiza Sheh et Shan
     Basing upon the above pollen characters, the genera Cyclorhiza Sheh et Shah and
Chuanminshen Sheh et Shan are briefly discussed.  They are two clearly delimitated
natural genera.
