冀北山地不同坡向白桦枝叶异速生长关系研究OACSTPCD
Allometric Relationship Between Twig and Leaf Sizes of Betula platyphylla on Different Slopes in Mountaineous Areas of Northern Hebei
当年生小枝作为植物生长的独立构件单元,研究其大小关系对于理解植物生存适应策略具有重要意义.以冀北山地不同坡向白桦枝叶为研究对象,测定小枝的茎干质量、叶片干质量、叶片面积、叶柄干质量以及小枝干质量,分析不同坡向白桦枝叶生长关系,揭示白桦枝叶生长对坡向的生态策略和适应性.结果表明:1)除茎干质量外,其余干质量皆显示为半阳坡显著大于阴坡,叶片面积在坡向间无显著差异.2)标准化主轴回归分析(SMA)表明,在小枝水平上,不同坡向间茎干质量与小枝干质量、总叶…查看全部>>
Current year twig is an independent component unit for plant growth,it is important to study the quantitative relationships that are relative to the twig growth for understanding the survival and adaptation strategies of a plant.In this study,we took the current year twigs of Betula platyphylla growing on differ-ent slopes in mountainous areas of Northern Hebei as the research objects,growth parameters of different parts of a twig were measured to analyze th…查看全部>>
