Summary

Plants don’t just endure stress—they use it. In this episode, Dr. José Leme joins me to explore how mechanical vibration, super cropping, and controlled water restriction affect plant physiology, trichome density, and secondary metabolite production. We also break down recent research on jasmonates, drought signaling, and why your method of measuring trichomes matters more than you think.
