Abstract
ABSTRACT
The present investigation entitled “Propagation of Berberis lycium Royle: an important shrub of
mid-Himalaya through seed and stem cuttings” 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 2017-2018. Berberis lycium is a medically important shrub /small tree belong to the family
berberidaceae. There is enormous biotic pressure on this shrub species and natural regeneration is poor. It is
very hard to propagate Berberis lycium through seed and stem cuttings. 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 bio-regulators on the germination of Berberis lycium. The harvested seeds
were stratified in perforated poly bags. Three batches of seed were placed for stratification at 15 days interval
for 15, 30 and 45 days at four different temperature viz., 11-22˚C, +5˚C, 0±1˚C and -5˚C. Gibberellic acid was
applied in three different concentrations (100ppm, 200ppm and 300ppm) and one control. In second experiment,
effect of various pre-sowing treatments and different potting mixture was studied under nursery conditions. In
third experiment effect of IBA under field condition was analyzed for the rooting behaviour. From the present
investigation it is concluded that a stratification period of 30 days at 0±1˚C temperature followed by soaking in
200 ppm of gibberellic acid excelled over other treatments and registered maximum germination percent
(70.00%), germination energy (60.00%), germination capacity (75.00%), mean daily germination (2.33) and
peak value (4.30).Among different pre-sowing seed treatments the seeds treated with cow urine registered
significantly maximum germination percent (65.33%), germination energy (61.33%), germination capacity
(65.33%), mean daily germination (0.63) and peak value (1.00). The seed sown in potting mixture consisting of
soil + sand + FYM in ratio 1:1:1 (M4) registered maximum seedling growth and biomass production parameters.
In field conditions, cuttings treated with different IBA concentrations, T5 (0.6%IBA+1%captan+2%sucrose-talc)
recorded the maximum sprouting percent (36.66%) and rooting percent (30.33%
