黑松雄花穗生长发育与出粉率研究

在荣成成山林场采用不同林龄随机调查的方法，进行了黑松生长发育不同阶段的形态特征及主要营养生长指标与其雄花穗数量间关系研究；在胶东半岛沿海防护林以及半岛内陆丘陵山区，进行了黑松和赤松雄花穗的成熟采收期和采集技术研究；通过实验检测手段，确定了黑松和赤松雄花穗不同年份实验室出粉率和实际生产出粉率；确定了黑松和赤松的雄花穗长度与松花粉出粉率的关系. 为松花粉的合理采集及产业化开发提供依据.

Growth development of the male anthotaxy of Pinus thunbergii parl. and its pollen percentage

The characteristics of vegetative growth and reproductive growth of Pinus thunbergii and the relationships between them were studied by using the method of random sampling in the Chengshan Forest Farm. The best harvesting time and the techniques of Pinus thunbergii and Pinus densiflora for pollen were established through investigation in the coastal shelter forest and the inland of Jiaodong Peninsula. Pollen amounts of Pinus thunbergii and Pinus densiflora in male anthotaxy were tested both in the lab and in the field, and the relationships between pollen percentage and length of male anthotaxy of Pinus thunbergii and Pinus densiflora were confirmed. This provides a firm basis for the collection and industrial development of pine pollen.
