【摘要】 [Objective] To discuss effect of snow melting time on characteristics of growth and phenological phase of Fritillaria unibracteata Hsiao et K.C.Hsia.[Method] In an alpine snow bed on the eastern Tibetan Plateau,the transplant test of F.unibracteata was carried out between early-melting portion and late-melting portion.Individual characteristics and phenological changes of F.unibracteata were observed.[Result] Height,area per leaf and aboveground biomass of F.unibracteata in late-melting portion were significant higher than those in early-melting portion.Snow melting time showed a strong influence on early phenological phases like plant emergence and first flowering,while it presented a weak influence on late phenological phases such as consenescence.[Conclusion] It was more advantageous for F.unibracteata to grow in late-melting habitats than in early-melting locations,which should be followed in artificial cultivation of F.unibracteata on Tibetan Plateau.
