SIU Researcher Dr. Jose Leme on Trichomes, Water Stress, and Biostimulants in Cultivation

What happens when you stress plants on purpose?In this video, we break down university research from Dr. Jose Leme’s lab on plant stress, trichomes, water deficit, and biostimulants.Topics covered:Stress signals vs real stressTrichome development and plant defenseWater deficit strategies (dry back vs dry out)Biostimulants like seaweed, humic acid, chitosan, and silicaHow timing, environment, and genetics affect outcomesSome of the results challenge common assumptions.If you're interested in plant science, controlled environment agriculture, or optimizing plant performance, this is worth understanding.Chapters00:00 Intro – Who is Dr. Jose Leme?01:20 The trichome methyl jasmonate experiment03:34 Why trichomes behave unexpectedly05:20 Trichomes as a defense mechanism10:45 Measuring trichomes (limitations)11:56 Size vs concentration24:09 Genetics vs environment34:27 Water stress experiment35:00 When stress backfires36:31 Nutrients vs stress37:00 Dry back vs dry out45:36 Pushing genetic potential46:10 Biostimulants and signaling47:05 What showed promise48:48 What’s still unknown
