本研究采用彩色标签法对不同种子性状的红松、榛子和榛子种子的扩散和命运进行了研究。我们的目的是确定的作用的比例的内核质量，每粒种子的热量奖励，和标签颜色影响种子去除率和种子的命运。我们预测，较高的籽粒质量和热量奖励的比例将有利于种子去除和缓存，而较低的将有利于种子消耗无论是在原位或去除后。我们的研究结果表明，籽粒质量的比例，而不是种子的大小，在决定种子去除率和种子的命运发挥了重要作用。种子C.与P相比，具有最低籽粒质量比例的异叶藓，无论其最大尺寸和/或质量，其去除率较低，缓存水平较低，但原位消耗比例较高。koraiensisandC. mandshuricaseeds。种子具有较高的热量奖励表现出更大的扩散距离。种核比例与种子的移出率和缓存率密切相关，而种子大小和船体厚度对种子扩散的影响较小，这可能是由于实验区小型啮齿动物具有更强的种子处理能力。我们的调查显示，标签颜色对三种种子的种子去除率和种子命运没有显着影响。
In the present study, colored tags were fastened to individual seeds to investigate seed dispersal and seed fates ofPinus koraiensis,Corylus mandshurica, andCorylus heterophyllawith different seed traits. Our aim was to determine the role of the proportion of kernel mass, caloric reward per seed, and tag color in affecting seed removal rates and seed fates. We predicted that higher proportion of kernel mass and caloric reward will favor seed removal and caching, while lower ones will facilitate seed consumption either in situ or after removal. Our results showed that the proportion of kernel mass, rather than seed size, played an important role in determining seed removal rates and seed fates. Seeds ofC. heterophyllawith the lowest proportion of kernel mass, regardless of their largest size and/or mass, had lower removal rates, lower level of caching but higher proportion of consumption in situ compared withP. koraiensisandC. mandshuricaseeds. Seeds with higher caloric reward exhibited greater dispersal distances. Seed kernel proportion was closely correlated to seed removal rates and caching rates, while seed size and hull thickness seemed to play less important role in affecting seed dispersal, probably because the higher seed handling ability of small rodents in the experimental areas. Our investigation revealed no significant effect of tag color on seed removal rates and seed fates of the three seed species.
