Investigations of the effects of 1:1 mixture of 8-hydroxyquinolene and saturated solution of Alpha-bromonapthalene on the meiotic process in Gyandropsis gyandra Linn. was carried out with an aim of exploring the nature of any mutagenic impart of the chemicals on normal meiosis in this plant. The combined mixture of 1:1 8-hydroxyquinolene and alphabromonapthalene affected first and second meiotic divisions significantly, causing chromosome stickiness (32.74%) at pachytene and anaphase-1. The mixture also disorganized the Metaphase-1 chromosomes causing bivalents to agglutinate into small groups leading to formation of ring bivalents (6.06%). Generally, chromosomes staining, configuration and separations were found to be greatly affected by the mixture. Heavily clumped bivalents characterized anaphase-1 separations in most pollen mother cells. This appeared like highly condensed chromosome masses with stretches of chromatid segments forming bridges which eventually culminated in a reasonably high level of restitution (18.32%). Most pollen mother cells obviously could not go through to second division.
Indigenous systems of medicine are one of the natural health care systems practiced by all human cultures irrespective of geographic realm since time immemorial. The rich repository of biodiversity in each area paves the way for the development of such healthcare rehearses. Kerala, the southernmost tip of Indian Peninsula is really blessed with luxuriant vegetation and biodiversity, and the same has immense role to meet indigenous healthcare needs. The present study reports the medicinal plants used by different tribal communities residing in Kasargod District in Kerala. Floristic and ethnobotanical tribal knowledge was collected through extensive groundtruthing and interviews. A total of 44 plants, their vernacular name, plant parts used and method of preparation are recorded. The medicinal potentialities of plants are important and could be explored to formulate newer drugs with more potential.
