用酶解压片方法观察了脐橙、中华猕猴桃、杜梨的胚囊。脐橙大多数胚囊中无核存在表现为败育,形态为近圆柱形。猕猴桃胚囊为一哑铃状,合点端较大而圆钝,珠孔端较小而尖锐,反足细胞呈“品”字形排列,杜梨开花当天其胚囊为八核时期,胚囊中央为一大液泡,二个极核细胞正在向中间运动。此方法能较迅速、较完整地观察到胚囊的结构和发育状态。 The enzymolysis tablet method was used to observe the embryo sac of navel orange, Chinese kiwifruit and pears. The majority of embryonic sac of the navel showed no abortion, the morphology was nearly cylindrical. Kiwifruit embryo sac is a dumbbell-shaped, large and dull point, the smaller and sharp beaked end, antipodal cells were “goods” shaped arrangement, the day Pear flowering embryo sac is eight nuclear period, embryo sac central A large vacuole, two polar cells are moving to the middle. This method can be more rapid and more complete observation of the embryo sac structure and development status.
