摘　　要：以湖北百合和大花卷丹为试材,采用常规压片法和LI-6400便携式光合测定系统对其进行核型和光响应曲线、光合速率日变化的分析。结果表明:湖北百合、大花卷丹染色体数均为2n=2x=24,其中湖北百合的核型公式为2n=2m+2sm+18st+2t属于3B型,大花卷丹核型公式为2n=4m+10st+10t属于3A型。Pn、Tr、Par比较发现湖北百合高于"大花卷丹",Co、Ci比较发现大花卷丹高于湖北百合。综合比较,大花卷丹午休现象更为突出。Taking Lilium henryi Baker and Lilium leichtlinii var.maximowiczii Baker as test materials,coventional tabletting method was adopted to measuring the mechanism of karyotype and the LI-6400 portable photosynthes was used to measuring system for light response curve,diurnal change of photosynthetic rate.The results showed that the chromosome numbers of Lilium henryi Baker and Lilium leichtlinii var.maximowiczii Baker were 2n=2x=24,which the karyotype formula of Lilium henryi Baker was 2n=2m＋2sm＋18st＋2tbelongs to 3Band the karyotype formula of Lilium leichtlinii var.maximowiczii Baker was 2n=4m＋10st＋10tbelongs to 3A.Pn,Tr,Par comparison showed that Lilium henryi Baker was higher than Lilium leichtlinii var.maximowiczii Baker and Co,Ci was higher than Lilium henryi Baker.By comparison,midday depression of Lilium leichtlinii var.maximowiczii Baker was more prominent.
