Abstract

The central part of the Western Ghats (i.e. Uttara Kannada District of Karnataka) was surveyed for tree species and regeneration using belt transects. Medicinally important trees were more in disturbed evergreen forests while undisturbed evergreen forests had proportionately more threatened species. Out of total 19 species of medicinally important threatened trees recorded , only Knema attenuata , Garcinia gummigutta and Artocarpus hirsutus showed a wider ecological amplitude with presence in disturbed and undisturbed evergreen forests. All other species were either confined to undisturbed forests or were rare in both types. Most of the threatened medicinal trees showed decrease in abundance in the disturbed evergreen forests. Species for which seeds or fruits are extracted like Myristica malabarica , Garcinia sp. , Hydnocarpus pentandra etc. there was a lack of adequate regeneration compared to density of trees and are at double disadvantage of habitat loss and regeneration loss.

Abstract

Investigation was carried out to propagate critically endangered medicinal plant species, Celastrus paniculata by using ischolar_main cuttings with different growth regulators. The various ischolar_main and shoot parameters recorded significantly higher in the ischolar_main cuttings treated with growth regulators as compared to control. The average higher ischolar_maining percentage (81.0) was recorded in the cuttings treated with IBA 2000 ppm against control (52.0). The average number of ischolar_mains per cutting was significantly higher in the cuttings treated with a commercial formulation Quic Root (19.23) followed by IBA 2000 ppm (16.75). The average higher field establishment percentage (95.0) was also observed in IBA 2000 ppm treated cuttings followed by commercial formulation Quic Root treatment. Quic Root was found to be the second best treatment next to IBA 2000 ppm for propagation of C. paniculata through ischolar_main cuttings.
