对广西4种丛生竹种子的长度、宽度、长宽比、硬实率、千粒质量等种子形态特性进行了分析，通过发芽实验测定了种子萌发能力。结果表明，4种丛生竹种子均为颖果，外带颖壳，分内稃、外稃；沙罗单竹种子长度、宽度及长宽比、硬实率与千粒质量最大；种子各指标如长度、宽度、长宽比与千粒质量呈极显著相关；不同竹种子发芽率和发芽势不等，且萌发速率也不相同，4种丛生竹竹子萌发最早始于第3天，沙罗单竹与黄竹的种子比吊丝竹、云南龙竹的种子具有更好的萌发能力，这和其种子在形态特征上的优势表现出一致性。 The seeds of four species of sympodial bamboo were investigated including length, width, ratio of length to width, hard rate, 1 000-grain weight and seed germination capacity. The results showed that the seeds of the four species of sympodial bamboo were caryopsis, with outside glume including palea and lemma. The length,
