松属植物的大、小孢子叶球发生及发育研究进展

Advances in the Occurrence and Development of Ovulate Strobilus and Microstrobilus of Pinus Linn

本文从形态学和解剖学两个角度对松属植物大、小孢子叶球发生、发育的特点以及大、小孢子叶球发育过程中存在的几种特殊现象进行综述,系统地总结了大、小孢子叶球发生部位、发生时间、分化阶段特征以及小孢子叶球中花粉的发育、大孢子叶球发育中颈卵器的形成等多个重点阶段,提出了继续开展相关研究的方向。

The characteristics of the occurrence and development of ovulate strobilus, microstrobilus and several special phenomena in the development from the perspectives of morphology and anatomy were summarized. The key parts of the occurrence, timing and the characteristics of differentiation stage of ovulate strobilus and microstrobilus as well as the development of pollen in microstrobilus and the formation of ovum in the development of ovulate strobilus. In addition, the direction of continuing research was raised.
