DescriptionControlled pollinations are vital in southern pine tree improvement programs. Effective pollinations depend upon three operations. First, female flowers must be enclosed in isolation bags when they are in the proper stage of development. Then, viable pollen must be supplied to the ovules when the female flowers are most receptive. Finally, the developing cones must be protected until maturity.
