| 摘 要： | 以20个小粒种咖啡种质为试验材料,通过盆栽试验,分析咖啡种质苗期生长量和根系形态差异。结果表明,各种质苗期株高、叶片数、分枝数差异显著,通过苗期株形分析,把小粒种咖啡种质分成高干、中等和矮生3个类型。M13、M14可作为高干型,CATUAI为矮生型鉴定的标准品种;CA ZHONGⅢ、M13为高干、多叶、多分枝品种,CATURRA、T8667为株高中等、多叶、多分枝品种,热引2号为矮生、多叶、多分枝品种;各种质主根长除了CA ZHONGⅡ较小以外,其他种质间差异不显著,各种质主根直径差异不显著;M13侧根长、根体积、根表面积显著大于CATUAI,参试的小粒种咖啡种质绝大部分都具有细而且数量较多的侧根,各种质间差异较小。侧根直径与侧根长为显著的负相关,地上部干物质累积量与地下部干物质累积量间呈显著的正相关,长势强壮,枝叶繁茂的植株,根系发达;各种质地下部和地上部生长相协调的根冠比在0.40~0.35。
