DescriptionControlled pollination of pines generally has been disappointing because cones contain too few seeds. We need to develop better techniques for collecting, extracting, and storing pollen, as well as better bagging procedures. A logical first step is to learn more about collecting and extracting pollen. In a recent study I found that extracting pollen of jack pine (Pinus banksiana Lamb.) and white pine (P. strobus L.) at a high relative humidity favors the development and maintenance of pollen vigor.
