烤烟种子催芽后包衣,种子发芽势提高0.50%~2.75%,发芽率提高1.00%~1.25%。种子催芽程度以种子露白40%~60%效果最佳,种子催芽后出苗期提前6~7 d,出苗整齐度好。经贮藏处理,随催芽程度的变化耐贮藏性变化较大,催芽程度越高,耐贮藏性越差,催芽后耐贮藏性与贮藏温度、催芽时间、包衣加工方法有关。烤烟种子催芽处理后对烟苗素质、产量及其经济学性状影响不明显。 Flue-cured tobacco germination after coating, seed germination potential increased 0.50% ~ 2.75%, germination rate increased 1.00% ~ 1.25%. Seed germination to the seed dew white 40% ~ 60% of the best effect, seed germination after germination early 6 ~ 7 d, emergence uniformity. After storage treatment, with the degree of germination changes storability change, the higher the degree of germination, the poorer storability, germination resistance after storage and storage temperature, germination time, coating processing methods. The effect of flue-cured tobacco seed germination on the quality of tobacco seedlings, yield and economic characteristics was not obvious.
