Abstract:: 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∶perlite=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 cormel diameter.The average propagation coefficient and averaged cormel diameter had an inverse relationship.
