摘要
不同温度对四个箭豌及两个苕子品种种子特性影响的研究表明,不同种和同种不同品种的箭舌豌豆及苕子种子的吸水率、发芽率、硬实率、损伤率差异显著。温度对上述种子特性的影响十分明显,但有阶段性,既在一定温度范围内变化不显著。箭舌豌豆种子硬实率主要受温度控制,而苕子。特别是早熟毛苕则主要受遗传性决定。种子损伤率(耐高温能力)因不同品种而受温度影响程度不同,但与种不同无关。
Four cultivars of commen vetch (Vicia sativa L. ) and two cultivars of hairy vetch (Vicia villosa ) were used to study the relationship between seed characters (including water absorbing rate, hard seed rate, seed germination rate and seed damage rate) and temperature. The results indicated that there are notable difference in seed characters among Vicia sativa L. and Vicia villosa Roth & Var . There were also marked difference in seed characters among cultivars of Vicia sativa L. Temperature gives more impact on hard seed rate, seed damage rate of Vicia sativa L. than that of Vicia villosa Roth & Var.
