Effect of pre-sowing treatments on germination and growth of French bean (Phaseolus vulgaris L.)
Author(s): Shivdeep and NS Dhillon
Abstract: The experiment was laid out to study the effect of pre-sowing treatments with growth regulators viz. Indole acetic acid (IAA), Salicylic acid (SA) and Gibberellin acid (GA3) with different concentrations like 50 ppm and 100 ppm on physiological and growth attributes of French bean. The seeds treated with growth regulators for 8 hrs. And 12 hrs. Duration along with three replications of treatments. The experimental approaches like plot size 2.5×2.5 m, spacing 45×15 cm and ridge & furrow planting method used and transplanting followed. The significantly maximum germination percentage (95.95%) recorded with 100 ppm concentration of IAA in this seeds soaked for 12 hrs. (T6) which was better over control (87.17%). The maximum change in seed diameter (0.86 cm) was noticed in T6 i.e. seeds treated with IAA 100 ppm concentration and soaked for 12 hrs. And minimum recorded in control (0 cm). The better length of radical (9.03 cm) when seeds treated with 100 ppm concentration of GA3 and soaked for 12 hrs. (T4). The minimum days taken to emergence (5.11 days) occurred with T6 i.e. seeds treated with 100 ppm IAA and soaked for 12 hrs. Over control. The results revealed that significant change in growth attributes of French bean like maximum plant height (66.46 cm), number of branches per plant (7.85), minimum days taken to 50% flowering (31.15 days) recorded when seeds treated with 100 ppm GA3 and soaked for 12 hrs. (T4) over control or water treated seeds.
