摘  要:
对杏品种‘张公园’在果实生长发育期间种胚的生长发育进行了观察分析,开展了种子成苗技术研究。结果表明:张公园杏在种子生长发育期间,子叶会出现异常现象,其表现为子叶形状不规则,局部内陷到比较严重的子叶内部局部凹陷、变褐坏死、皱瘪等,由此导致种胚不能正常萌发。经过胚培养和种子低温冷藏后播种2种途径进行种子成苗技术研究发现,在种胚发育到果实成熟前3周左右采样,进行胚培养和种子经低温处理后播种成苗,均可获得比较理想的成苗率。

摘  要:
The study was carried out on development process of seed and embryo seedling of 'Zhanggongyuan'apricot.The results showed that cotyledons progressively appear abnormal symptom during seed development,for example irregular cotyledons shape,cotyledon part inner hollow,brown and necrosis,etc.As a result embryo could not normally germinate.The results of embryo culture and sow after seed cold storage showed that the seedlings rate in three weeks before fruit mature were hinger.
