摘要
根据管道模型理论并通过生物染色剂染色实验,对榆树的水分年轮输导模式进行了研究.研究发现,榆树不同年轮的水分输导能力不同;不同年轮间水分横向输导不明显,纵向输导在同一年轮内也不是均衡向上输导,呈明显的管道状输导,这一结果完全符合管道模型理论.
The patterns of water transportation along Ulmus pumila were studied based on pipe model through biological coloration. Results are as follows: the capacity of water transport between growth rings is different; The horizontal transportation of water between growth rings is not obvious; The water transportation is not harmoniously upward and shows the pattern of pope model, which results conform to completely pipe model theory.
