野生蔬菜高葶韭种子形态特征及发芽条件研究

Study on Seed Morphology and Germination Condition of Allium obliquum L.

高葶韭是新疆野生葱属蔬菜中具有重要开发利用潜力的种质资源。本试验以高葶韭为材料,对其种子形态及其在不同温度和光照条件下的萌发特性进行了观测。结果表明,高葶韭种子黑色、倒卵形,表面纹饰呈现斑块状,具明显的颗粒状突起,大小为3.49mm×1.88mm×1.40mm。在15℃/25℃变温条件下,种子发芽较快、较整齐,其发芽率、发芽势及发芽指数分别可达到81.33%、80%和4.37,与0、5、10、15、20、25、30℃恒温处理以及0℃/10℃、5℃/15℃、10℃/20℃和20℃/30℃变温处理下种子的发芽率、发芽势及发芽指数间存在极显著差异;光照对高葶韭种子萌发的促进或抑制作用在各处理间差异不显著。

Allium obliquum L.is an important wild vegetable resource.The seed morphology and the germination characteristics of this species at different temperature and light conditions were studied in this article.The results showed that seeds wereblack and oboval with granular ornamentation on the seed coat,and the size was 3.49mm×1.88mm×1.40mm.The best germination condition was 15℃/25℃ thermoperiods.In this condition,germination rate,germination energy and germination index could reach to 81.33 %,80 % and 4.37 respectively,which were different from the other treatments significantly.The seed had no strict requirements for light.
