Seed Quality as Affected by Mid Cone Diameter in <I>Pinus roxburghii</I> Sargent

Abstract

The present investigation was undertaken to find out the effect of mid cone diameter classes on seed quality in Chir pine. The cones were grouped into small (5-<6cm), medium (6-<7cm) and large (7-<8cm) cone diameter classes. The large cones showed superiority in germination percent, germination value, germination capacity, germination energy and germination speed over other cone diameter classes. Also, there existed a positive and highly significant correlation between cone diameter and different seed parameters. Therefore, large cones (in diameter) should be given preference for quality seed collection.
