本文对福州杧果种质圃内37份杧果种质资源部分植物学特性进行了描述评价。结果表明,杧果品种间的树姿具有差异性;树形多数属圆头形,中央骨干枝不明显;幼嫩枝条、叶形、叶表面状态、叶尖类型等4个性状,均存在丰富的多样性;幼叶颜色差异明显。由此可见,不同杧果在相同生长环境下的植物学性状表现一定差异性。相关性分析表明,主干高度与干周、叶片宽度、叶片长度和叶柄长度等呈极显著相关;干周与叶片宽度及叶柄长度呈极显著相关,与叶片长度呈显著相关;叶片长度与叶柄长度呈显著相关;叶片宽度与叶柄长度呈极显著相关。
In this paper, we described and described the botanical characteristics of 37 germplasm resources of mango germplasm in Fuzhou. The results showed that there were differences in the tree stance among the mango cultivars. Most of the tree buds belonged to the shape of a round head and the central branches were not obvious. The four traits such as tender shoots, leaf shape, leaf surface state and tip type were all abundant The diversity of young leaves is obvious. It can be seen that there are certain differences in the botanical characters of different mango fruits in the same growth environment. Correlation analysis showed that there was a significant correlation between trunk height and dry week, leaf width, leaf length and petiole length. Dry week had a significant correlation with leaf width and petiole length, and had significant correlation with leaf length. Leaf length and petiole length There was a significant correlation between leaf width and petiole length.
