摘要:
对水翁Cleistocalyx operculatus 幼苗的生长过程进行研究。结果表明,水翁幼苗的株高、地径生长具有阶段性的特点,利用Logistic 曲线拟合了水翁幼苗株高与地径的生长模型,决定系数均在0.95 以上;其生长进程可划分为4 个阶段,即出苗期、生长前期、速生期和生长后期;根冠比总体呈下降趋势,生长重心逐渐由地下部分向地上部分转移;叶面积比与叶根比呈先下降后上升的趋势;地径与主根长、单株总叶面积等形态指标以及地上生物量、地下生物量以及单株总生物量等生物量指标之间均存在较强的正相关关系(r>0.92,P<0.01);根冠比与株高、地径、单株总叶面积、主根长、地上生物量、地下生物量、单株总生物量均存在负相关关系;地上生物量、地下生物量、单株总生物量之间均存在极显著的正相关关系(r>0.97,P<0.01)。
Abstract:
Experiments were conducted on growth rhythm of Cleistocalyx operculatus seedlings in Guangzhou, Guangdong province in 2014. Theresults show that the growth of height and ground diameter of C. operculatus had different stages. Logistic growth curve was fitting the growthchanges, with determination coefficient above 0.95. Height and diameter growth of seedlings could be divided into 4 stages with nearly similar date.Root-shoot ratio decreased indicating underground growth increased while aboveground growth decreased. Leaf area ratio and leaf area root ratiodecreased and then increased. There was a significant positive correlation among ground diameter and main root length, total plant leaf area,aboveground biomass, underground biomass , the total plant biomass(r >0.92,P<0.01). Significant negative correlation existed among root-shootratio and height, ground diameter, total plant leaf area, main root length, aboveground biomass, underground biomass, the total plant biomass.Significant positive correlation between aboveground biomass, underground biomass, and the total plant biomass was observed(r>0.97,P<0.01).
