Effect of pre-sowing treatments on germination parameters of Dalbergia latifolia Roxb.



Dalbergia latifolia belongs to family Fabaceae. The species is slow-growing and it is threatened by overexploitationfor its timber and illegal logging. Large plantations in Java and India have been established to meet the demand for Indianrosewood. Therefore the demand for nursery grown seedlings of D. latifolia has increased immensely for planting underafforestation programmes. But poor natural regeneration and low germination rate poses a serious threat to its establishment.An experiment was conducted at College of Forestry, Sirsi to know the effect of pre-sowing treatments on the germinationparameters of Dalbergia latifolia with a total of eight different treatments. Significantly higher germination percentage(70.00%), mean daily germination (3.33), peak value (6.35), germination rate (5.11) and germination value (21.15) wererecorded in the seeds treated with tap water for 12 hours. Seedling vigor index (1376) and biomass (1.166 g fresh weight and0.607 g dry weight) were also maximum in seeds treated with tap water for 12 hours. The results indicated that seeds treatedwith tap water had profound and significant impact on seed germination parameters.
