摘　　要：排胶时间是限制天然橡胶产量的关键因子之一,而乳管伤口堵塞物的形成决定着排胶时间的长短。橡胶粒子凝集与乳管伤口堵塞物的形成密切相关,其凝集过程主要受胶乳中的蛋白质调节。笔者综述橡胶粒子凝集相关蛋白的研究进展,旨在为橡胶树乳管堵塞机理的研究及排胶相关分子标记的研发提供参考资料。Duration of latex flow after tapping is a erutial factor that limits rubber yield, which is mainly determined by the plugging formation at the end of severed laticifers. The protein in latex plays an important role in the regulation of rubber particle aggregation, which is closely associated with the plugging formation. In order to provide clues for elucidating the mechanism by which the severed latieifers are plugged and for exploring molecular markers applied in predicting the yield potential and ability of latex flow of clones or wild germplasms of rubber tree in Hevea breeding program, the progresses of the isolation and characterization of proteins related to rubber particle aggregation in latex were reviewed.
