Pollen Production, Microsporangium Dehiscence and Pollen Flow in Himalayan Cedar (Cedrus deodara Roxb. ex D. Don)

Pollen dispersal patterns in Himalayan cedar

Pollen grain traps set at strategic positions and distances from source trees show that Cedrus deodara pollen travels over 196 m and dispersal is strongest in a downhill direction. Khanduri and Sharma (pp. 587-593) propose that 190 m is the minimum isolation distance for ensuring uncontaminated seed production in seed orchards.
