背景情况:
- 橄 (Olea europaea L.) 是一种与自身不相容的物种.
- 果实发育的典型特征是单种的果.
- 种植模式的变化可能会发生,包括双种子和无种子的水果.
研究的目的:
- 研究不同授粉剂对三种自我不相容的橄品种种植模式的影响.
- 在各种授粉处理下分析水果和种子组,种子流产,双种和种子重量.
- 了解母亲和父亲对橄果和种子特性的影响.
主要方法:

Pollination and Flower Structure
79.9K
Flowers are the reproductive, seed-producing structures of angiosperms. Typically, flowers consist of sepals, petals, stamens, and carpels. Sepals and petals are the vegetative flower organs. Stamens and carpels are the reproductive organs.

Oogenesis
71.0K
In human women, oogenesis produces one mature egg cell or ovum for every precursor cell that enters meiosis. This process differs in two unique ways from the equivalent procedure of spermatogenesis in males. First, meiotic divisions during oogenesis are asymmetric, meaning that a large oocyte (containing most of the cytoplasm) and minor polar body are produced as a result of meiosis I, and again following meiosis II. Since only oocytes will go on to form embryos if fertilized, this unequal...
