赤霉酸对海甘蓝种子发芽和幼苗生长的影响

Effect of Gibberellic Acid on Seed Germination and Seedling Growth of Seakale

用０．０２５％、０．０５０％、０．０７５％和０．１００％浓度的赤霉酸溶液按１２ｈ、１８ｈ、２４ｈ和３０ｈ浸泡海甘蓝（ＣｒａｍｂｅｍａｒｉｔｉｍａＬ．）种子，以风干种子和自来水浸泡２４ｈ为对照。结果表明，多数处理对海甘蓝种子发芽和幼苗生长有明显的促进作用，但规律性不明显。０．

The seeds of seakale (Crambe maritima L.) were treated in the combinations of four concentrations of gibberellic acid(0025%,0050%,0075%,0100%) and four soaking times (12h,18h,24h 30h).Dry seeds and 24 h of tap water soaking were used as control. Most treatments of Gibberellic acid can obviously improve the seed germination and seedling growth of seakale,but the regularity is not very good.The conbination of 0025% gibberellic acid and soaking for 18 hours is the best for the germination of seakale seeds and the growth of their seedlings.
