Palynomorphs and ecological factors of autumn bloom ing plants in Jianghua i hilly region
1. School of Life Science, Anhui University, Hefei 230039, China; 2.Key Laboratory of Ecological Engineering and Biotechnology of Anhui Province
The Palynomorphs of 24 autumn blooming p lants from J ianghuai hilly region are described and il2
lustrated by lightmicroscope (LM). The results show that the pollen grains are globose to long globular in shape.
The maximum and minimum P /E values are Yucca sm alliana Fern. and Osm anthus fragrans ( Thunb. ) Lour. The maximum pollen grain is Luffa cylindrica (L. ) Roem. , and the minimum is Clad rastis w ilson ii Takeda. The types of apertures include monosulcate, 3��6 colpate, irregular pantocolpate, tricolporate, 2��4 porate and pantoporate. The ornamentation of exine are sp inulose, finely reticulate, coarsely reticulate, granular and stripe2perforated. The present study p rovides the main ecological factors, including geographical position (31°31′��32°37′N, 116°40′��117°52′E) , altitude (70��20 m) , annual p recip itation (900��1 000 mm ) and annual accumulated temperature of ≥10�� (4 500��5 300 ��) for the distribution area.
