Abstract

The floristic study is necessary to understand the present diversity status and conservation of forest biodiversity. It has been realized that the study of local or regional flora is of much more significance than those covering big areas because explorations can be carried out intensively in small areas with damaging consequences. Understanding species diversity and distribution patterns are important to evaluate the complexity and resources of these forests. In the present study, the medicinal floristic diversity of Pilavakkal dam Foothills of the Western Ghats comprised of 127 species belonging to 42 families and 100 genera. Fabaceae, Malvaceae and Lamiaceae were dominant families with 23, 11 and 10 species, respectively. The total number of species includes 55 herbs, 23 shrubs, 37 trees and 12 climbers. Totally 127 important medicinal plant species are recorded in Pilavakkal dam Foot Slopes of Western Ghats. Psydrax dicoccos is vulnerable in this list, 27 plants species are Least Concern and Mangifera indica comes under the Data Deficient and 98 plants species evaluated are not categorized by IUCN. This study provides basic information about the medicinal flora and conservation status of the Pilavakkal dam Foothills of Western Ghats. It would also be helpful for the identification of flora and to derive conservation policies and make sustainable use of plant resources

Abstract

A rare kind of tropical plant in the Santalaceae family is Santalum album. The active ingredient in S. album, santalol, is also referred to as sandalwood oil and is highly prized in the fragrance business for its fixative qualities and pleasant, enduring scent. Out of all the species in the genus Santalum, S. album has the greatest oil concentration (about 6%). The wild plants are overharvested for their wood, which is used to make santalol, as well as for other uses including woodcarving and traditional medicine. S. album is an easily hurt plant. Thus, the creation of an in vitro mass propagation protocol for this valuable species is necessary in order to generate homozygous clones with large yields for the establishment of sandalwood plantations. In this study, a full-strength MS medium supplemented with varying concentrations of BAP and Kn (0.5-2.5 mg/l) was used to cultivate the shoot tip and intermodal portions of S. album that were collected from the wild. The maximum shoot development (4.50±0.50) occurred at a BAP concentration of 1.5 mg/l. IBA and IAA were added to the rooting medium along with the developing shoots. IBA (2.0 mg/l) had the highest mean number of roots (4.90±0.25) and root length (5.75±0.47 cm). Shoots that had been successfully rooted were moved to the field to harden. According to the current study, MS medium with 1.5 mg/l of BAP and 2.0 mg/l of IBA is an appropriate technique for micropropagating and conserving S. album is fragile tree species.
