通过定期测定瓦松种子的发芽率,观察幼苗的抗旱能力,以及在人工栽培条件下观察瓦松的生活周期。结果:新收种子无休眠期,发芽率高达97.4%,而8个月后仅剩约40%;子叶展开后的幼苗可承受2个月以上的干旱胁迫,而未展开者迅速死亡;种子直播苗和野生苗移栽试验证明瓦松需3年以上才能开花,而非文献记载的2年。 By periodically measuring the germination rate of the seedlings of Vaseriana, the drought resistance of the seedlings was observed, and the life cycle of Vasson was observed under artificial cultivation conditions. Results: The newly harvested seeds had no dormancy period, the germination rate was as high as 97.4%, and only about 40% remained after 8 months; the seedlings after cotyledon development could withstand more than 2 months of drought stress, and the undeveloped ones died quickly; Transplanting trials of seedlings and wild seedlings proved that it took more than three years for flower heads to flower, not the two years documented.
