This paper made a systematic research on Lonicerafulvotomentosa Hsu et S.C. Cheng, which grows well inkarst areas, from its biological characteristics, such asmorphology, growth and physiology. The main conclusions asfollows:(1)From the viewpoint of morphological anatomy, it hastypical xerophyte structures such as well-developed epidermisand tissues that transport water effectively, small leaf area,dense floss under the leaf surface, high stoma density, thesmall opening degree, thick cuticle, well-developed xylem andpalisade tissues, etc. The pollen of L. fulvotomentosa isseems to be spherical, and has 3 grooves, much bulge on theepidermis evenly. The shape of pollen is an important featureon taxonomy. The ripe fruit has from 1 to 18 seeds, some fruitbranch has 135 berry, its diameter is up to 0.8 centimeter.(2)From the viewpoint of growth, L.
本文从形态解剖、生长发育的节律、光合生理特性以及种子萌发生理等生物学特性方面对喀斯特适生经济植物黄褐毛忍冬进行了较为系统的研究,得出以下结论:(1)在形态解剖上,黄褐毛忍冬根茎中含有发育良好的周皮和输导组织,导管密度大,横截面宽,周皮的形成具有节制蒸腾、通气作用和保护组织免受外界环境影响的作用,宽的导管对水分的输导效率高;叶片密被绒毛,面积较小,气孔密度大、开度小,厚的角质层和发育良好的木质部和栅栏组织等是典型的旱生结构;黄褐毛忍冬花粉近球形,具3 孔沟,表面具均匀分布的小刺,刺间具网状纹理。

In order to explore the extraction method of proteome and technique of 2-DE, we compared the extraction method between the TCA-ac-tone and the Tris-HCl, and improved the key steps of 2-DE. The Tris-HCl extraction was the most appropriate for Antiaris toxicaria seed proteome analysis because of the highest resolution and more informative 2-DE map. Those were the solid basis for the later research of studying on the discrepancy expression proteomics of Antiaris toxicaria Seed.
