本研究以海岛棉、陆地棉、亚洲棉、草棉和云南木棉等五个种的71个品种(系),特别是陆地棉中的鄂光棉、鄂沙28、鄂荆92、鄂荆1号等为材料。系统地观察了棉花螺旋对称结构的全息规律;比较了不同螺旋棉株上棉铃种子的成苗、出叶、结铃和经济状况;研究了亲代与子代螺旋对称结构的全息关系,探讨了螺旋对称结构全息的分子学基础;建立了棉花螺旋对称全息系统,并阐明其理论与实践意义。从棉花分类研究起,有人注意棉花叶在茎上的螺旋分布(WaH,G、1907,CooK,o.F.1911)。十几年后冯泽芳研究中棉形态时(1924),观察到叶、枝、花瓣的螺旋结构。汪若海(1980)进一步观察,印证了冯泽芳观察结果的普遍性,对棉花单个器官的螺旋结构和方向作了说明,并指出研究其发生机理的必要性。一般则不以为然。棉花螺旋结构是否存在系统,遵循什么规律,如何发生,有何依据,在理论和实践方面存在什么意义,有没有必要作进一步研究等一系列的问题,应作出有序的回答。1982—84年进行了系统的再观察和田间试验。便于提高对棉花结构的认识,推动棉花发生理论的研究,促进生物学认识论和方法的发展。
In this study, 71 varieties (lines) of five species of sea island cotton, Upland cotton, Asiatic cotton, cotton grass and Yunnan kapok were cultivated, especially in Upland cotton, Ersha 28, Ejing 92, No. as the material. The holographic regularity of cotton spiral symmetry structure was observed systematically. The seedling emergence, leaf-out, boll-opening and economic status of cotton boll seed on different spiral cotton plants were compared. The holographic relationship between the helix symmetry structure of parental and offspring was studied. The molecular basis of symmetrical structure holography; cotton spiral symmetry holographic system was established and its theoretical and practical significance was clarified. Since the classification of cotton, attention has been paid to the helical distribution of cotton leaves on the stem (WaH, G, 1907, CooK, o.F. A decade later when Feng Zefang studied the cotton morphology (1924), the spiral structure of leaves, branches and petals was observed. Further observation by Wang Ruohai (1980) confirms the universality of Feng Zefang’s observations, explains the spiral structure and orientation of individual cotton organs, and points out the necessity of studying its mechanism. Generally disagree. There are a series of questions about whether cotton spiral structure exists system, what law to follow, how to happen, what basis it has, what meaning exists in theory and practice, there is no need to study further, and we should give an orderly answer. In 1982-84, systematic re-observation and field trials were conducted. Facilitate the understanding of cotton structure, promote the theory of cotton occurrence, and promote the development of biological epistemology and method.
