本试验对桃的早熟品种“新端阳“(Amsden june)和中熟品种“传十郎”的胚胎形态发育阶段进行了观察,得出他们的胚胎形态均有以下几个阶段:卵细胞—合子—球形胚—心形胚—鱼雷胚—子叶胚;两品种胚胎形态的同一阶段距盛花期后的天数有差异,探明早熟桃“新端阳”盛花期后28天左右其胚胎是心形胚阶段。本研究所得结果对于更有效地开展桃的胚胎培养具有重要的参考价值。
In this experiment, we observed the morphological and morphological stages of the peach cultivars ”Amsden june“ and ”Zhongjuro“, and found that their embryo morphology has the following stages: the egg-zygote- Spherical embryo - heart-shaped embryo - torpedo embryo - cotyledon embryo; two varieties of embryos from the same stage from the full bloom after the number of days are different, proven early peach ”new end of the sun" about 28 days after the flowering stage of its embryonic heart-shaped embryo stage . The results obtained in this study have important reference value for carrying out embryo culture more effectively.
