Effect of seed treatments on plus trees of Buchanania lanzan in South-Eastern Rajasthan

Abstract

The present investigation entitled “was carried out during April 2019 to October 2019 at College of Horticulture and Forestry Jhalawar. The experiment was laid out in Randomized Block Design (factorial) with twelve plus trees and three concentrations (0%, 2.5%, 5%). Out of twelve plus trees the Number of days for first seed germination recorded in PT1 and the highest germination percentage was observed in PT2 (56.30%). Minimum peak germination period (14.61days) and highest peak value (4.46 days) recorded in PT1. In case of concentration (H2SO4 5%), the Number of days for first seed germination was recorded earlier than other concentrations and the highest germination percentage (68.89 %) and survival percentage (90.30 %) were observed in PT1. Minimum peak germination period (10.00 days) and highest peak value (6.91 days) recorded in concentration (H2SO4 5%). Significantly increased the seedling growth attributes like seedling height, collar diameter and number of leaves (27.28 cm, 4.02 mm and 14.27) were observed in C2 (Conc. H2SO4 5%). In case of twelve plus trees PT1 gave maximum seedling height (20.64 cm) and highest number of leaves (9.62), and maximum collar diameter observed in PT4 (3.33 mm).
