Abstract:
Wendlandia exserta Roxb. DC. Commonly known as Chila, Ratela, Tikli, is well distributed throughout the sub-Himalayan tract upto 1400m elevation, especially on the areas that are vulnerable to landslides. It is a good fuel wood species and also provides small timber. Larger areas can be covered with this species, particularly which are sloppy and prone to soil erosion. Intensive research is required on the propagation of this species. The present investigation was conducted at Dr. Y.S. Parmar University of Horticulture and Forestry, Nauni, Solan. The seeds were stored at different temperatures viz., Room temperature, 10 ± 1 ^oC and 0 ± 1 ^oC. Thereafter, the seeds were treated with different growth regulators- IAA, IBA, NAA, GA₃, KIN, and Ethrel and salt solutions (MgSO₄ and KNO₃) at different soaking periods, viz., No soaking, 6 hour and 12 hour. Germination studies were carried out to record the Initiation of germination, germination percentage and germination energy. The experiment was laid out in completely randomised design (factorial). The results revealed that treatment with GA₃ without soaking under 10 ± 1 ^oC gave higher germination percentage (38.48%). The seeds took minimum 11.82 days for germination at 0 ± 1 ^oC and 10.89 days (for no-soaking). The interaction effect of storage temperature with soaking period for germination per cent with maximum value of 28.47% (12 Hrs. soaking at 0 ± 1 ^oC). For initiation of germination, the interaction of storage temperature with various treatments, storage temperature with soaking period and chemical treatment, storage temperature with soaking time was significant with minimum values in control at 0 ± 1 ºC, 6.73 days under control at 0 ± 1 ^oC (with no soaking) and 9.33 days in MgSO₄ for 6hrs soaking at room temperature and IAA at 0 ± 1 ^oC with no soaking. The interaction of storage temperature with soaking period and treatment, storage temperature with soaking periods was significant for germination energy with maximum value 47.27 per cent (no soaking at room temperature) and 77.05% in Kinetin at 0 ± 1 ^oC with 6hrs soaking.
