Effects of a Biostimulant on the Heat Tolerance Associated with Photosynthetic Capacity, Membrane Thermostability, and Polyphenol Production of Perennial Ryegrass

Physiological responses of perennial ryegrass (Lolium perenne L.) treated with or without Macro-Sorb Foliar (FOLIAR) and subjected to optimal growing conditions or high air temperature stress (20, 28, and 36ºC) were investigated in vivo using three separate growth chamber experiments
