摘要: 以罗布麻种子为试验材料,对其进行形态特征观测;同时研究不同抑菌处理、不同光照条件和不同浸种时间对种子萌发的影响。结果表明:罗布麻种子呈卵圆状矩圆形,黄褐色,表面具细条纹,顶端有白色绢质毛,种长为2.437 mm、种宽为0.681 mm、种皮厚度0.015 mm、种子大小指数为0.025。无菌水处理下发芽率发芽势均为最高,作为抑菌试剂较为适宜;光照条件对罗布麻种子发芽率发芽势的影响不显著,相较之下,罗布麻种子适宜在自然光条件下发芽。种子发芽率和发芽势在8h时最高,发芽时间最短,种子浸种处理以8h为宜。

Abstract: Apocynum seeds as experimental materials,their morphological characteristics were observed, and the different antibacterial treatment, different light conditions and different soaking time on seed germination were researched.The results showed that the seeds of apocynum was ovoid oblong,brown,surface striolate,white silky hairs at the top, which was 2.437 mm long,0.681 mm wide, thickness of the seed coat 0.015 mm, seed size index 0.025. Sterile water treatment had the highest germination rate, as antibacterial reagent was appropriate;light conditions on the germination rate of apocynum effect was not significant, in contrast, apocynum seeds were suitable to germinate in natural light conditions.The seed germination rate and germination potential were highest in 8h, germination time was the shortest, seed soaking treatment should be keep 8 h.
