【摘要】 测定昆明市场常见的10个矾根品种的净光合速率,测定值经过方差分析和t检验.结合不同矾根品种的光合速率值和"双峰"特征,分析其在昆明的适应性,指导引种.结果显示,"提拉米苏""马蕾都""红石榴""红色火焰"和"鸡尾酒"具有典型双峰和明显"午休"现象,适合在昆明引种;"红辣椒""梅子布丁"和"冰裂"呈现不典型双峰,对中午阳光耐受力弱,可考虑引种于光照较弱的室内环境;而"秋枫"和"黑发丝"出现多峰和多次休眠,昆明地区不建议引种.更多还原

【Abstract】 The net photosynthetic rate of 10 kinds of Heuchera micrantha varieties in Kunming market was measured.The measured values were tested by ANOVA and T-value.The varieties with typical "bimodal" and obvious "siesta" phenomenon are "tiramisu" " Marydu" "red pomegranate" "red flame" and "cocktail".However, "red pepper" "plum pudding" and "ice crack" don’t have typical bimodal,and they have weak tolerance to midday sunlight.Therefore,these plants can be applied to the environment with weak sunlight or indoor environment. "Autumn maple" and "black hair silk" appears multimodal and have more than once dormancy,so planting and application of these two varieties are not recommended in Kunming.更多还原
