摘要
采用7种不同方法对银合欢Leucaena leucocephala种子进行处理,结果表明,用98%的浓硫酸对银合欢种子进行处理5 min效果最好,发芽率达86%;其次是水温80℃浸种10 min,发芽率达74%;80℃高温干燥10 min和机械摩擦种皮效果比较差,发芽率仅19.3%和15.3%;酒精、40%的氢氧化钠、不同浓度萘乙酸(NAA)浸种对银合欢的发芽率没有影响,最佳处理的大田试验结果与实验室结果相吻合。
Hard seed exists in many legumes＇seeds. The seed coat of hard seeds must be properly treated so that permeability is increased without injuring the embryo. Seven methods are used to treat the hard seed of Leucaena leucocephala. It is indicated that the best method is to immerse seeds in 98 sulphuric acid for 5 minutes, the germination percentage is 86%;soaking seeds in 80℃ hot water for 10 minutes, the germination percentage is 74%;the results of drying seeds in high temperature or breaking the seed coat are relatively low, the germination percentage is 19. 3% and 15.3%, respectively; It has no effect in L. leucocephala germination percentage of immersing seeds in alcohol, 40 sodium hydroxide and different concentrations of NAA. The comparison of the best treatment in the field test to the lab test is accordant.
