Effect of Seed Provenance and Mother Tree of Quercus branti Base on Primary Establishment in Yasuj

This study was conducted to investigate the effect of provenance of Persian oak species on its acorn morphological traits and growth and survival parameters in different latitudes of Zagros region. Mother trees of three sites from northern (Baneh), central (Khoram-Abad) and southern (Yasuj) Zagros region were selected and their acorns planted as a completely randomized design in common garden in Yasuj. Acorn morphological traits and growth parameters of seedlings like height, collar diameter, number of leaves and volume in June and September and survival of seedlings were measured. Analyse of variance showed that all acorn morphological traits except acorn diameter at first one of 0.1 height and number of acorn per kg had difference significant. High latitudes provenance had highest value of width, navel diameter and acorn volume and lowest value of length, length to width ratio. Growth and survival traits of seedlings from three provenances were significantly different so that seedlings originated from Baneh were showed highest value growth and survival traits. Results of correlation showed that width, navel diameter and acorn volume were positively and length, length to width ratio and number of acorn per kg were negatively correlated with latitude and growth traits of seedlings. The highest amount of vitality was belongs to seedlings of southern Zagros. Results of cluster analysis also showed that seedlings germinated from mother trees of Baneh and wide navel diameter of acorn had better primary establishment in Yasuj.
