Auxins' influence on physiological processes adaption of SAL (Shorea robusta) seedling cultivated outside their natural habitat (AABR), Chhattisgarh

Abstract:
Exogenous treatment with various auxins (IAA, IBA, and NAA) was used to evaluate physiological parameters on the acclimation pattern of Sal seedlings at 15-day intervals for 10 days. Initially, young (three-leaf) seedlings were taken from the AABR natural forest in Chhattisgarh. These saplings were raised at the departmental nursery in polybags filled with nursery soil. All the auxins used during this experiment were at a concentration of 100 ppm. The seedlings treated with NAA 100 ppm hormone absorbed the most carbon, followed by IAA 100 ppm hormone treatments. IBA 100 ppm hormone treatment resulted in the highest rate of stomatal conductance (1.416 mol H2O m-2 s-1) and IAA 100 ppm treatment resulted in the lowest rate (0.015 m H2O m-2 s-1). The rate of evaporation in all auxin hormone treated seedlings was greater than in the control group of saplings. Saplings fed with NAA hormone exhibited the greatest evaporation rate (1.53 mol H2O m-2 s-1) compared to the control set, followed by IAA and IBA hormone. In terms of sapling growth and establishment, IBA at 100 ppm surpassed other auxins.
