摘　　要：对药用植物通关藤种子的形态特征、吸水特性、含水量、生活力及发芽特性等进行了研究,并采用不同激素及浓度处理种子,分析种子的发芽特性,为培育优质种苗奠定基础。研究结果表明,通关藤果实为蓇葖果,纵径(80.84±2.07)mm,横径(11.22±0.29)mm,每个果实内含有的种子(24.03±0.29)粒,千粒重为(22.82±0.024)g,种子含水量为7.93%;通关藤种子无休眠特性,为正常型种子,150 mg/L GA3能显著提高种子发芽率,其余各类激素处理不能明显提高种子的发芽率。Studied on morphological characteristics, water absorption, water content, viability and germination characteristics through seeds of M. tenacissima handled with different hormones and different concentrations to analyze the biological characteristics of seeds to lay the foundation for cultivating high quality seedlings. The results showes that the fruit of M. tenacissim was follicles that contained （ 24.03± 0.29 ） grains. The longitudinal diameter and transverse diameter were （80.84± 2.07 ） mm and （ 11.22 ±0.29 ） mm. The thousand seed weight was （22.82 ± 0. 024） g and seed moisture content was 7.93 %. There had no dormancy characteristic that belonged to normal type seed. 150 mg/L GA3 could improved the germination rate of seed significantly, others hormone treatment did not.
