METHOD: ID of phenolics CONDITIONS: Green House - 16h light at 20-26C with RH from 60-90% and 32,000 lux at soil level METHOD NARR: The contents of the heads of type A trichomes was collected. HPLC was used to detect phenolics.tivity was measured as percent transittance at 440 nm. NMR analysis was used in identification of phenolics. RESULTS NARR: Relatively few phenolics are present in the type A trichomes of ber and pld. In pld n-chlorogenicic acid oxidation activity of pld was 2-fold greater than ber. AUTHOR EXPLANATION: The presence of p-hydroxyphenylpropionic acid glucose ester in both species suggests it is an important factor in trichome mediated insect res
