Morpho Physiological, Yield, and Transgenerational Seed Germination Response of Soybeans to Temperature

Temperature is the primary factor affecting the morpho-physiological, developmental, and yield attributes of soybean. Despite several temperature and soybean studies, functional relationships between temperature and soybean physiology and yield components are limited. An experiment was conducted to determine the optimum temperature for soybean gas exchange and yield components using indeterminate
(Asgrow AG5332, AG) and determinate (Progeny P5333 RY, PR) growth habit cultivars.  Plants grown outdoors were exposed to 5 day/night temperature treatments, 21/13, 25/17, 29/21, 33/25, and 37C/29C, from flowering to maturity using the sunlit plant growth chambers.
