摘　　要：以美丽豹子花(Nomocharis basilissa)、多斑豹子花(Nomocharis meleagrina)、开瓣豹子花(Nomocharis aperta)3个不同野生品种为试材,研究了不同基质(草煤土、珍珠岩、锯末、草煤土∶腐殖质土∶珍珠岩=1∶1∶1)和同一基质(草煤土∶腐殖质土∶珍珠岩=1∶1∶1)不同物种下豹子花属植物鳞片扦插繁殖能力的差异。结果表明:基质配比及物种间差异对豹子花属植物扦插繁殖有显著影响;扦插基质结构的保水、保肥性决定了豹子花鳞片的萌发、小籽球的生根率及健壮程度;其中以草煤土及草煤土∶腐殖质土∶珍珠岩=1∶1∶1混合基质最优;不同基质中籽球平均直径主要依赖于母体鳞片大小,无显著差异;相同基质下,出芽时间开瓣豹子花最短、多斑豹子花居中、美丽豹子花所需的时间最长;开瓣豹子花平均繁殖系数相对较高,而平均繁殖系数与籽球直径存在一定反比关系。Taking Nomocharis basilissa, Nomocharis meleagrina, Nomocharis aperta 3 wild species as test materials,the reproductive capacity scale cutting leopard genus at different substrates（peat,peat ： humus ： pertite= 1 ： 1 ： 1） and the different species of leopard genus at the same substrates（peat ： humus ： perlite= 1 ： 1 ： 1） were studied. The results showed that：effect of scale cutting propagation was depended on substrate types and inter-species difference. In different substrates the germination rate and average propagation coefficient were determined by breathability, water-retaining property and nutrient-preserving capability of substrate structure. Biomass soil and mixed substrate which was mixed by peat ： humus ： perlite= 1 ： 1 ： 1 were more suitable for propagation of Nomocharis. The averaged cormel diameter was depended on size of cutting scales and was no significant difference among different substrates. In different species Nomocharis aperta had the shortest budding time, higher average propagation coefficient but lower averaged eormel diameter. The average propagation coefficient and averaged cormel diameter had an inverse relationship.
