摘要:
[目的]从显微和超微层面探究油茶柱头和花柱的结构特征,可为探讨油茶自交不亲和性的细胞学机制提供理论依据,同时也为油茶杂交育种工作奠定基础。[方法]以开花当天的雌蕊为试验材料,利用细胞学方法研究油茶柱头和花柱的显微及超微结构特征。[结果]油茶雌蕊具完整的柱头、花柱和子房结构,湿性柱头其表面密布乳突细胞,排列紧密,细胞质浓厚,细胞器丰富,细胞间具有丰富的分泌物。基本组织细胞内含物和细胞器较少,细胞壁薄且壁外无分泌物。整个花柱由3 5根独立花柱组成,上端约2 /3部分相互分离形成离生区,从2 /3处开始到花柱基部相互连接形成合生区。每根花柱中空,由外表皮、基本组织和花柱道内表皮构...
摘要(英文):
[Objective] To investigate the structural characteristics of the stigma and style of Camellia oleifera at the microscopic and ultramicroscopic levels and provide a theoretical basis for elucidating the cytological mechanism of breeding self-incompatibility reactions in C. oleifera style, while at the same time to establish a theoretical foundation for hybrid breeding of C. oleifera. [Method] Using the pistil of C. oleifera on the day of blooming as the experimental material, the microscopic and ultramicroscopic structural characteristics of C. ...
