| 摘 要： | 分别以Ｅｌｖａｘ４２６０、丙烯酸树脂作为人工种子的外膜，前者保水性能较好，但影响人工种子发芽．低浓度的丙稀酸树脂作为人工种子外膜，对发芽有一定促进作用，但无明显保水效应；而高浓度或低浓度长时间浸泡，保水效应好，但影响人工种子的发芽．冰冻切片观察外膜为一层连续的致密膜．

| Abstract: | Elvax4260 and acrylic resin were respectively used as spermoderm of artifical areds.Elvax4260had better water-retaining ability,but it was disadvantage in germination of artifical seeds.Low concen-iration of acrylic resin could promote germination of artifical seeds in some degree when it was used as spermoderm,but water-retaining ability did not increase obviously. When artifical seeds were immersed in acrylic resin solution for a longer time,the germination rate dropped but water-retaining ability increased.Meanwhile,the artifical spermoderm was composed of a laper of continous and compact membrane by observation of freezing section. |
