摘要: 本文用扫描电镜和光镜详细研究了人工培养的中国产卷柏科Selaginellaceae 11种卷柏的雌配子体的发育特点和形态特征, 11种卷柏分别是卷柏Selaginella tamariscina(Beauv.)Spring小卷柏, S. helvetica(L.)Link, 鹿角卷柏S.rossii(Bak.)Warb., 疏叶卷柏S. remotifolia Sp-ring, 西伯利亚卷柏S. sibirica(Milde)Hieron, 中华卷柏S. sinensis(Desv.)Spring, 薄叶卷柏S. delicatula(Desv.)Alston, 异穗卷柏S. heterostachys Bak., 细叶卷拍 S. labordei Hieron.伏地卷柏 S. nipponica Fr.et Sav.和圆枝卷柏S. sanguinolenta(L.)Spring, 在比较了每种雌配子体形态发育特点的基础上, 讨论了卷柏科轉配子体在形态演化上的可 能趋势, 认为有"赤道轴缩減型"和"极轴缩減型"之分, 这与根据孢子体将 卷柏科分为Homoerphyllum和Heterophyllum两类的观点相吟合, 并探 讨了用雌配子体形态发育为卷柏类分组所能提供的依据。其中9种系首次报道。

Abstract: Using the light microscope and SEM, the characteristic of the morp-hological development of the culturing gametophytes of 11 speices in theSelaginellaceae from China have been studied. They are Selaginella tamariscina (Beauv.) Spring, S. helvetica (L.) Link, S. rossii (Bak.) Warb., S.remolifolia Spring, S. sibirica (Milde) Hieron., S. sinensis (Desv.) Spring, S. delicatula (Desv.) Alston, S. heterostachys Kak., S. labordei Hieron. S.nipponica Franch. et Sav., and S. sanguinclenta (L.) Spring. On the basis of the characteristic of the morphological development ofeach species, the possibility of morphological evolution on the female gam-etophytes of Selaginellaceae has been discussed. We consider that the fem-ale gametophtes may be divided into two typies:Shortening equatorialaxif type and Shortening polar axis type. These two typies are identicalwith the views of dividing The genus Selaginella into Hemoerphyllum andHeterophyllum on the sporophytes And the Heterophyllum seems to be grouped, owing to the morphological development of female gametophytes. Amony them the female gametophytyes of 9 species are the first rep-ort.
