29 wrz 2015 · Pine trees put out an incredible amount of pine pollen in the spring. When it looks like yellow ash or scum is floating on the ponds and lakes, that's the time to get to harvesting pine...
cycle, provide useful guidelines for cone induction, assist in forecasting pollen, cone and seed produc-tion, enable more effective pollination and pollen management for breeding and cone and seed pro-duction, and explain many of the causes for cone and seed loss in natural stands and seed orchards. The manuals are intended for use by students and
