摘要
对匍匐翦股颖新品系、原始群体及引进品种在贵州独山县进行了品种比较试验,主要对物候期、抗逆性、植物(生物)学习性、坪用性状进行了鉴定比较和分析评价。结果表明:匍匐翦股颖新品系在独山试验点不能抽穗,无法形成花序,不能进行生殖生长;新品系与2个对照品种相比,青绿期长、抗旱、分蘖能力强,匍匐茎节间短、茎细、叶片较小等;其综合坪用性状如密度、颜色、抗病性、抗虫性以及越夏性能等方面均明显优于对照。
The new Agrostis stolonifera L. Line was tested to identify and evaluate its phenophase, growth habit, adversity resistance and lawn character compared with the local original variety and Cato variety introduced from U. S. A in Dushan. The results showed that the new line could not head and form anthotaxy normally in Dushan and its agronomical characters with the longer green period, stronger drought resistance and tiller capacity, short internode, slender stem and small leaf, and comprehensive lawn character of density, color, disease and pest resistance, and oversummer capacity were better than the local original variety and Cota.
