摘要:
以164株大树的调查数据为基础,对元宝枫各性状进行相关性分析,再进行变异类型划分。结果表明,元宝枫营养生长性状之间呈极显著的正相关;果实千粒重与果实其它性状间呈显著正相关;种子千粒重与地径、株高、冠幅、果厚、果实千粒重呈显著正相关。根据生长状况,元宝枫可划分为营养生长型和生殖生长型2大类。根据果实形态特征,将生殖生长型再划分为宽翅型、小翅型和大翅型3类。营养生长型是选育叶用品种的材料,主要选择指标是抽枝数和叶片数;大翅型是选育果用品种的材料,主要选择指标是结实数和果厚。
Abstract:
Based on the investigation of 164 trees of Acer truncatum, the relativities among characters were analyzed and the variable types were compartmentalized. The results showed that there were significant positive correlations among vegetative traits, and obvious positive correlation between weight and other traits of fruitage (samara). According to the growth character, the variable types of Acer truncatum were classified into vegetative type and reproductive type, and the reproductive type were classified into wide wing type, small wing type and big wing type in accordance with the fruitage shape. The plustrees of leaf oriented one were selected from vegetative type mainly based on the number of branch and leaf, and the plustrees of fruitage oriented one were selected from reproductive type mainly according to the number of fruitage and the thickness of fruitage.
