摘　　要：为了探索野生百合的繁殖特性,对秦巴山区5种野生百合32个生态型的32个品系进行了鳞片扦插试验。结果表明:不同野生百合鳞片扦插的籽球大小和繁殖系数不同,其中宜昌百合繁殖的籽球最大,繁殖周径达到了2.91cm,重量达0.53g,宝兴百合较低,分别为2.05cm和0.14g;卷丹百合的扦插繁殖系数最高,为2.10,宝兴百合最低仅为0.75;同一种类的不同生态型之间扦插繁殖特性也差异较大,如陕西省汉阴县平梁乡西林村的宜昌百合籽球周径、重量和扦插繁殖系数分别高达3.45cm、0.71g和1.67,而甘肃省舟曲县峰迭乡沙沟村的宜昌百合则分别为2.57cm、0.33g和0.99;扦插鳞片重量与其繁殖籽球大小之间存在极显著的正相关,其中鳞片重量与籽球周径和重量的相关系数分别为0.716和0.714。A scale cutting propagation experiment was carried out with 32 strains from 32 ecotypes belong- ing to 5 species of wide lilies occurring in Qin-ba mountainous areas to explore their reproductive character- istics. The results indicated that the cutting propagation of the scales from different species of wide lilies produced different sizes of bulb-lets as well as propagation coefficients. The bulb-lets of Lilium leucanthum were the biggest,with the circumference of 2.91 cm and weight of 0.53 g,while that of L. duchartrei were 2.05 cm and 0. 14 g respectively. As for the coefficients of cutting propagation, L. lancifolium reached 2.10, ranking the highest,while that of L. duchartrei was 0.75. The reproductive characteristics of differ ent ecotypes of the same species varied from one another. For example,the circumference,weight and prop- agation coefficient o{ L. leucanthum＇s bulb-lets from Xilin Village, Pingliang Township, Hanyin County, Shaanxi Province were 3.45 cm,0.71 g and 1.67 respectively. However,the relative values were 2.57 cm, 0.33 g and 0.99, respectively, for L. leucanthum＇s bulb-lets from Shagou Village, Fengdie Township, Zhou- qu County,Gansu Province. It was observed that there were significantly positive correlation between the weight of the scales and its bulb-lets,the correlation coefficient of the weight of scales with the circumfer- ence of bulb lets was 0. 716,and with the weight of bulb-lets was 0. 714.
