Abstract

Studies made with Jatropha curcas on seed priming with different growth regulators, temperatures and durations with the constant seed to solution ratio of 3:2 revealed that priming with IBA 200 ppm at ambient temperature for a duration of 12 to 24 h enhanced the quality characters of Jatropha seedling raised at nursery to evaluate its performance in production of quality seedlings.

Abstract

Pongamia pinnata is one of the most promising tree borne oil seed species. Ten better performing accessions mainly based on fruiting were evaluated. Uniform size semi-hardwood cuttings were made and were treated with IBA @ 600 ppm. The cuttings were measured, after 75 days of planting for ischolar_main length, shoot length, collar diameter, fresh weight and dry weight. The shoot length, collar diameter, fresh weight and dry weight had shown significant difference between the sources. Broad sense heritability was highest for ischolar_maining (99.58%) followed by fresh and dry weight. Fresh weight showed high genetic advance. The sources Mundara (Tikamgarh) and Khadauli (Agra) performed better in terms of dry matter production as well as ischolar_maining.
