Abstract

Phloridzin, a chalcone derivative possessing plant growth regulating properties was applied as foliar sprays at fortnightly intervals on Solanum viarum Dunal plants grown under pot culture conditions starting from early seedling to the flowering and fruiting of the plants. The treatments consisted of 0 (control), 1, 10, 100 and 1000 mg/l of phloridzin. The physiological effects of phloridzin at different concentrations on the vegetative growth and development and the glycoalkaloid contents of the berries were studied. It was concluded that phloridzin at the highest concentration stimulated plant height, leaf number and yield of berries, whereas the lowest concentration increased the yield of solasodine only.

Abstract

Rheede named nineteen species of ferns in Malayalam in his Hortus Malabaricus (Vol. 12, 1703). The botanical identity of these species made by eminent authors through ages has been studied. The study reveals that the names which were ascribed to these taxa earlier are mostly invalid now. The present work is devoted to establish their current botanical names through close examination of Rheedean plates and literature and current nomenclatural studies.

Equisetaceae a unigeneric family with only one extant genus. Equiseturn L. having fifteen species and seventeen hybrids in the world, is represented by six species and one interspecific hybrid in India. The present treatment of the family provides historical notes, key from subgeneric to species level, general morphology of the taxa, their type citation, world and Indian distribution, discussion and notes on anatomy, cytology, gametophyte, micromorphology, ecology, chemistry and uses.
