摘要: 用四唑染色法与目测法相结合测定珙桐种子的生活力。试验表明,在贮藏了近一年的时间里有外果皮、中果皮的种子生活力迅速地从98.0%降到8.0%,而没有外果皮、中果皮的珙桐种子生活力并没有出现明显的变化,表明珙桐果实外果皮、中果皮在种子贮藏期间对珙桐种子的生活力影响非常大。

关键词: 珙桐, 果皮, 种子生活力

Abstract: According to the research,the viability of seeds with mesocarp decreases sharply from 98.0% to 8.0%,but the viability of seeds without mesocarp has not any significant change in nearly one year.So Davidia involucrata seeds' epicarp and mesocarp affect the seeds' viability greatly.

Key words: Davidia involucrata, pericarp, seeds' viability
