外引高羊茅草种的生物学特性研究

以39个美国高羊茅草坪草品种为供试材料,于1998年9月在福建农林大学试验教学农场进行试验。通过对景观品质、密度、质地、颜色、耐践踏性、弹性、日生长速度、覆盖率、成坪速度、叶面积指数和分蘖数等11个主要性状的观察表明,该种草坪具有景观品质优、耐践踏、弹性强、颜色大都较为浓绿等多种优点,是一个有极具开发潜力的草坪草种。以11个主要性状为依据,对39个品种进行聚类分析,定阈值为5.4为分类标准,初步将所有品种分为五大类。

Study on Biological Characteristics of Introduced Tall Fescue in Fuzhou

Thirty nine tall fescue varieties were introduced from America for studing biolo characteristicson the experimental farm of Fujian Agriculture and Forestry Universty in September, 1998. Eleven main characters including visual quality, density, texture, color, tolerance, elasticity, growth rate, coverage, turf formation speed, leaf areaindex and tilling capacity of all varieties were measured.The results indicated that tall fescue varieties had propertiesof excellent visual quality and tolerance,fine elasticity,and dark green color. Based on the eleven characters of performance,with the aid ofcluster analysis, these varieties could be devided into five types.
