Provenance Variation and its Analysis in Myrica esculenta Buch.-Ham. Ex D. Don
AbstractMyrica esculenta Buch.-Ham. ex D. Don is a multipurpose tree occurring throughout Nepal between 1000-2100m asl. Provenance variation in this tree from four different parts of Kathmandu valley and two hilly regions of central Nepal were studied. The provenances are located in different altitudinal ranges and diversified climatic conditions. Substantial variability in morphological traits and flavonoid contents were observed in natural populations representing six provenances. Nagarkot and Shrinagar stands of M. esulenta were likely to be superior to other stands for their growth and other morphologial characters. Statistically, large variation was observed among provenances for stem diameter, wood specific gravity and height of the plants. Highly significant positive correlation was observed for height and stem diameter. The natural variations in populations are considered important for tree improvement, selection, hybridization and breeding programmes.
