The PGR used to induce parthenocarpy in tomatoes is- A. Auxin B. Gibberellin C. Cytokinin D. ABA
Option A. Auxin is a plant growth hormone needed for plant growth and development. When auxin is bound to a receptor (eg: auxin-binding proteins), it activates stimuli pathways and then activates gene expression. Mostly 2,4-D is responsible for inducing parthenocarpy in tomatoes.
