为 提高报 春花种子 活力和幼 苗的抗 逆性 ， 以 Ａ Ｂ Ｔ 生根 粉 不同 剂型 、不 同浓 度浸 泡 处理报春花 种子， 进 行了播种 发芽试 验。结果 表明 ， 经 Ａ Ｂ Ｔ 生 根粉 浸 泡处 理 后， 发 芽率 、发 芽速率、发 芽指数、 活力指数 等活力指 标均明 显提高， 以６ 号 Ａ Ｂ Ｔ 生根 粉２０ ｍｇ Ｌ 浸泡２４ｈ 的处理效果最 佳。电导 率值和干 鲜比低 于 Ｃ Ｋ， 与种子 活力存在 负相关 关系。
In order to improve seed vigor and resistance of seedlings, Primroses seeds were treated with different dosage forms of ABT rooting powder and soaked in different concentrations for seed germination test. The results showed that the vigor index of germination rate, germination rate, germination index and vigor index increased obviously after soaking the ABT rooting powder, and the best treatment effect was when soaked with 20 mg L 6 A B T rooting powder for 24 h . Conductivity and dry matter ratio were lower than C K, which had a negative correlation with seed vigor.
