The effect of seed coat removal on seed germination of pinus gerardiana wallich ex D. Don. Chilgoza pine

Mohammad Saeed, C.A. Thanos


Pinus gerardiana is known as “chilgoza pine” which yields small edible seeds. The chilgoza pine is a small to medium sezed tree occasionally attaining a height of 24m and a girth of 3.5m. the pine is confined to the eastern Afghanistan parts of Pakistan and India. In our studies we have investigated the effect of seed coat removal on seed germination of P. gerardiana and have determined the optimum germination temperature germination. When germinated under various constant temperatures the optimum for germination was found to be 20 c, matching  the average spring temperature prevailing in its habitat.
