The impact of variability of the type of Siberian cedar by seed scale apophysis on the seed peel firmness

The seed peel firmness of Siberian cedar morphological forms (by seed scale apophysis) has been studies. The existence of differences on the seed peel firmness indicators between the forms is theoretically based by the nutcracker’s activity. The results of the experiments prove the given assumption. It is shown that nuts from the cones with plain apophysis type require the relatively less maximum power and tension, but more time on their cracking. To use the seeds of the given morphological trees’ forms is prospective for the production of cedar kernel.
