| 摘 要： | 本文研究了太行山针阔混交林内10种植物的生理生态学特性。结果表明:10种植物的蒸腾强度为0.58-1.89克/克(鲜重)·小时,日平均耗水量为6.96-22.68克/克(鲜重),叶片含水量为70.7-82.6％,水分亏缺在10-40％之间;叶绿素含量为1.48-8.46毫克/克(干重),叶绿素a/b值在0.4-0.6之间。

| Abstract: | The paper is a report of the physi-ccologycal characteristics of 10 plan species on theropencedrymion in Taihang mountain. The results of the experiment turned out to be clear that the transpiration rates of the 10 plant species ( Populus davidiana, Bctula albo- sinensis, Juglans mandshurica, Corylus heterophylla, Viburnum mongolicum, Cotoneaster multiflorus, Rosa bella, Acanthopanax giraldii, Smilacina japonica, Paris verticillata) were 0.58- 1. 89g · g-1FW · h-1, the mean weight of day loss water was 5.84-18.91g · g-1FW, the content water in the leaves was 70.7-82.6%and the water dificit ware 10-40%.The results of the experiment also exhibit that the chlorophyll content was 1.48-8.46mg · g-1DW and chlorophylla / b was about 0.4-0.6. |
