Vacuum Collection of Douglas-Fir Pollen for Supplemental Mass Pollinations

摘要

An Aget Cyclone dust collector and pollen-collection equipment were developed and field tested. About 100 cc of pollen could be collected per minute by four workers using one machine. Number of filled seed per cone from controlled pollinations made with vacuum-collected pollen was significantly more than filled seed numbers from controlled pollinations made with nonvacuum-collected pollen.
