dc.description.abstractABSTRACT The present investigation entitled “Effect of pre sowing seed treatment and growth bioregulators on germination performance of Vitex negundo L.” was conducted in laboratory and nursery of the Department of Silviculture and Agroforestry, Dr. Y S Parmar University of Horticulture and Forestry, Nauni, Solan-173230 (HP) during 2015-2016. Vitex negundo (L.) is a medically important shrub /small tree belong to the family verbenaceae.There is enormous biotic pressure on this shrub species and natural regeneration is poor. Vitex negundo L. can be easily propagated through stem cuttings and root suckers. Propagation through seeds is hindered due to its poor viability. Seed is reported to possess double dormancy i.e. embryo dormancy in addition to a mechanical dormancy imposed by an impermeable seed coat. A very little information is available concerning the germination of this species. Therefore, the objective of the present study was to examine the effect of different treatments and bioregulators on the germination of Vitex negundo. The freshly harvested seeds were stratified in sand. Three batches of seed were placed for stratification at 15 days interval for 15, 30 and 45 days at two different temperature viz. 0±1oC and room temperature. Gibberellic acid was applied at three different concentrations (100ppm, 200ppm and 300ppm) including control. Kinetin was also applied at three different concentrations (100ppm, 200ppm and 300ppm) including control. In another experiment effect of various pre-sowing treatments was studies under nursery conditions. From the present investigation it is concluded that a stratification period of 30 days at 0±1oC temperature followed by soaking in 200 ppm of gibberellic acid excelled over other treatments and registered maximum germination percent (12%), germination energy (6.67%), germination capacity (14%), mean daily germination (0.26) and peak value (0.44). Besides this stratification period of 30 days at room temperature followed by soaking in 200 ppm of kinetin was found to be best for other kinetin treatments. It was observed that the gibberellic acid proved better for seed germinability as compare to kinetin. Among different pre-sowing seed treatments the seeds treated with cow urine registered significantly maximum germination percent (8%), germination energy (6.33%), germination capacity (13.00%), mean daily germination (0.11) and peak value (0.18). The seed sown in potting mixture consisting of sand, soil and FYM in 1:1:1 ratio (M4) registered maximum seedling growth and biomass production parameters.en_US
