以哈尔滨地区推广的“戈雪拉”和“小实”草莓品种为材料，采用常规石蜡切片法，荧光技术和透射电镜技术，对草莓受精、胚和胚乳的发育过程进行观察，其结果如下：１．草莓属于多心皮离生单雌蕊，柱头较小，表面有栅状排列的乳突细胞，花柱细长，中央可见有较发达的引导组织，子房内１枚横生胚珠，单珠被，厚珠心，蓼型胚囊，利用荧光法可清楚看到落在柱头上的花粉萌发，花粉管的延伸途径，即由柱头一花柱引导组织—子房内壁—胎座—胚珠表面—进入珠孔。２．胚的发育过程与大多数双子叶植物基本一致，先后经历了合子—二细胞原胚—球形原胚—心形胚—鱼雷形胚—成熟胚等阶段，胚发育属紫菀型，胚的形态呈直立型。３．草莓属核型胚乳，先后经历初生胚乳核—胚乳游离核—胚乳细胞—胚乳逐渐被胚吸收等过程，戈雪拉品种幼胚发育中，在其周围具有一个特殊的结构 Taking the “Gexuela” and “Xiaoshi” strawberry varieties popularized in Harbin as materials, the process of strawberry fertilization, embryo and endosperm development was observed by conventional paraffin section method, fluorescence technique and transmission electron microscope. The results are as follows: 1. Strawberry belongs to the polygamy free single pistil, stigma smaller, the surface of the grid arrangement of papillary cells, style slender, the central can be seen more developed guide organization, ovary 1 lateral ovule, single bee, thick Pearl heart, Polygonum type embryo sac, the use of fluorescence method can clearly see falling on the stigma of pollen germination, pollen tube extension of the way, that is, by a stigma style guide organization - ovary wall - placenta - ovule surface - into the beads . 2. Embryonic development process is consistent with that of most dicotyledonous plants. It has experienced stages of zygotic-two-cell primitive embryo-globular embryo-heart embryo-torpedo-mature embryo stage. Vertical type. 3. Strawberry genotype endosperm, has experienced the first endosperm nucleus - endosperm free nucleus - endosperm cells - endosperm was gradually embryos absorbed process, Gexuela species immature embryo development, in its surrounding has a special structure
