论新概念“裸子不裸”

Commont On The New Concept——The Gynosperma is Not Real. Gynospermism

松柏类以外的裸子植物发生较早,是由裸枝状的穗子类(Stachyosperma)的种子蕨(不具心皮叶或孕性叶)演化出简易的种子保护组织;而被子植物则从有心皮叶或孕性叶的叶子类(phyllosperma)的种子蕨演化出有子房结构的种子植物包括有花植物。尽管裸子植物适应演化形成一些适应机能结构而繁盛一时,由于大部分结构的缺陷,在地质变迁而引起的生存条件变化过程中被自然淘汰,只有那些自身结构适应性较强的如银杏、松柏类幸存而随后发育得更完善。被子植物是更能适应较复杂的环境并演化和发育出更完善的结构如心皮、子房这样复杂的种子保护结构。当所谓的裸子植物和被子植物并列出现在地球上经受同样的环境考验时,裸子植物已演化出套被和珠被的附加次生生长(珠被内出现维管束)的保护组织,这样的保护组织的作用和被子植物由子房壁发育出来的保护组织在功能上是一致的,但在起源方面则有不同的来源,反映出植物系统发育的多样性。

Gynosperma exclusive of the conifers originated from the nake twig stachyosperma that belonged to the seed ferns (pteridosperma, no reproductive carpidillum) and initiated simple seed's protective tissue during its evolusion; however, Anginosperma originated from the phyllosperma that belonged the seed ferns (Peteridosperma, having reproductive carpidillum) and initiated ovlue; the poster kind of plant included all flower plants. Gynosperma did adaptive evolusion to form some adaptive functional structures and were temporary flourish in age time, because of themself's defectstructures, almost of them were filtered out by the nature during geographic vicissitude that caused the survive condition completely change; So, only those prossessed strong adaptive function such as Ginko、conifers、cycads could do well development. Anginosperma were such a group of plants that could adapt to more complex enviroment, and formed complete seed protective structures for example the carpidium and ovlue. On the surface of the earth, when Gynosperma and Anginosperma existed simultaneously and faced the same eviromental trial, Gynosperma had evolved and formed integument and outer-integument's appendage second growth (vasculocrtissue apeared in the integument); such a kind of tissue on protective function was equal to the ovlue initiated by Anginosperma. But in origination, Gynosperma's second growth proteetive tissue differed from Anginosperma's; this showed the multiform of botany's phylogenesis.
