Influence of GA₃ and IAA and their Frequency of Application on Seed Germination and Seedling Quality Characters

Abstract

Effect of plant growth regulators on seed germination and seedling characters in terms of root length and shoot length. The seeds of sesame variety TVM -1 were treated with different concentration of gibberlic acid (1.0, 2.0, 3.0 and 4.0 mg/l) and indole acetic acid (1.0, 2.0, 3.0 and 4.0 mg/l). From the results, it was observed that the GA 3 and IAA at 2.0mg/l had regulatory effect on seed germination and seedling characters. Maximum germination, root length and shoot length was observed at 2.0mg/l in GA 3 and 2.0mg/l in IAA than control. And GA 3 at 2.0gm/l was found to be more efficient to modify seed germination and seedling characters when compared to IAA and control.

Influence of Nano Formulation on Augmenting the Seed Quality in Groundnut (Arachis hypogaea L.)

“…It induces the fast activation of hydrolysing enzymes which are involved in seed germination process. Fastest absorption of water also hastens the speed of germination and better seedling establishments, which was supported with the following research findings (Koornneef et al, 2002;Subash et al, 2014 andSakthivel, 2016).…”
