中文摘要：

鼠类对壳斗科植物种子的捕食作用十分强烈,从而影响此类植物的更新。栓皮栎和枹栎是中国西南地区常绿阔叶林主要树种,不仅有重要的经济价值,而且还可用于植树造林。对栓皮栎和枹栎种子分别进行包衣地表、无包衣地表、包衣埋藏和无包衣埋藏等4种处理,并跟踪各种处理种子被鼠类捕食的情况。结果表明：各处理之间种子的中位存留时间显著不同,包衣埋藏后的种子存留时间显著长于未包衣且放置于地表的种子,埋藏显著地降低了鼠类对这2种种子的捕食;埋藏及包衣处理能够很好地保护栓皮栎和枹栎种子免于鼠类的捕食,有利于种子存留并萌发建成幼苗。该方法可用于人工播种造林以提高造林成活率。

英文摘要：

Rodent predation on acorn is very intensive, which affects the regeneration of plant. Quercus variabilis and Q. serrata are the dominant tree species in evergreen broadleaved forests in Southwest China. They are not only of great economic value, but also favorable for local forestation. In this paper, their acorns were under four treatments, i. e. , coated but not buried, coated and buried, buried but not coated, and neither coated nor buried, and the fates of these acorns were followed up. The results showed that the median survival time of the acorns differed significantly with the treatments. The survival duration of coated and buried acorns was significantly longer than that of the acorns neither coated nor buried. Burial significantly reduced the predation of acorn by rodents, and coating effectively protected the acorns from predation. Both coating and burial increased the probability of acorns survival and seedlings recruitment. The results of this study could be used for artificial seeding plantation to increase the survival rate of forestation.
