Techniques for collecting, handling germinating, and storing of pollen of the filbert (Corylus spp.)

Summary

Temperature and humidity immediately before dehiscence were important in maintaining viability and germination of filbert pollen. Air temperatures at or above 23°C during dehiscence and pollen storage resulted in nonviability after 8–24 h. Cut branches bearing elongating catkins when exposed to temperatures of 18°±2°C during dehiscence yielded viable pollen. Manganese and boron added to the medium did not significantly increase germination, while 10–100 p.p.m. boron appeared to inhibit it. Storage tests indicated that filbert pollen viability may be maintained at 92% relative humidity and −18°C for at least 12 months.
