种子硬实是物种延续对环境的一种特殊适应,硬实种子具有很高的潜在活力[1-2]。硬实种子破除硬实后活力水平显著提高[3-5]。豆科牧草因普遍硬实率高,活力无法体现,导致出苗率低、出苗不整齐,故严重影响了牧草的田间建植,成为豆科牧草人工栽培中不容忽视的重要问题。救荒野豌豆(Vicia sativa L.)、窄叶野豌豆(Vicia angustifolia L.)、山野豌豆(Vicia amoena Fisch)和大花野豌豆(Vicia bungei Chwi)为豆科野豌豆属多年生 Seed hard is a continuation of the species on the environment a special adaptation, hard seed has a high potential energy [1-2]. Hard seed break hard real activity levels significantly increased [3-5]. Leguminous pasture because of the general high rate of hard, vitality can not be reflected, resulting in low emergence rate, emergence irregular, it seriously affected the forage field planting, artificial legume forage cultivation can not be ignored important issues. Vicia sativa L., Vicia angustifolia L., Vicia amoena Fisch, and Vicia bungei Chwi are perennial pea legumes
