%X he fruits of Loranthaccae are berries or drupes composed of epicarp,pulp and seeds,with pulp having a weight of 0. 026-0. 123g, 42. 1 %-47. 20% of the whole fruit, heavierthan either the epicarp or the seeds and supplying more food to the birds. There is no rest pe-riod for the seeds and they can germinate in fruit ,with axis of embryo,sucker or even thecotyledons coming out but the axis of embryo not going out through the epicarp to continuedevelop. When the birds looking , for food, they remove epicarp or the epicarp with pulp ,makethe glutionous pulp naked and stick to the bark of trees ,then germinate and develop there.In Xishuangbanna the seeds of Loranthaceae were spread mainly by the birds such asplain flowerpecker . fire-breasted flowerpecker searlet-backed flowerpecker and yellow-ventedflowerpecker for flowerpeckers. The bodies of such kinds of bird are all small and light ,withsharp snout and talons. They movc quickly .and have small stomaches with a thin wall so thatthe digesting ability is weak .After being swallowed .all the seeds oet into intestines directlywith the pulp partly digested .and stayed in the intestines only for a short time,so the seedsare all kept survival well.The main way of spreading seeds of Loranthaceae is by means of birds. Birds swallowthe seeds without epicarp or with epicarp and pulp.digesting a part of the epicarp and pulp intheir intestines ,then exereting the seeds out of their boides immediately or when they fly toother trees. As a result . the seeds are spread to different distances. The second way for shortdistance spreading of the seeds often happened by throwing seeds around trees or the branch-es of its host trees when birds are picking the fruits.
