Effect of Indole 3-Acetic Acid on seed germination of Lablab Purpureus L.
Abstract
Lablab purpureus L.with its ability to out-yield conventional crops, especially during the dry season, and its enhanced nutritive value, is a fodder crop of great significance for the Tropics. Lablab can be used advantageously as a cover crop. The current investigation was carried out to study in vitro regeneration potential in Lablab bean Lablab purpureus L. at various concentrations of plant growth regulator, i.e., Indole 3-acetic acid (IAA) on seed germination. A great deal of information relating to seed germination practices shows that these plant growth regulators were effi cient in overcoming dormancy leading to rapid seed germination. A significant result was obtained for IAA at (4 ppm and 5 ppm) compared to other treatments. Regenerated plants were successfully acclimatized and transferred to the green house with 70% survival rate. All the plants appeared morphologically uniform with normal growth pattern.
