Research The nexian phalaris breeding programme

If coumarin and coumarin derivatives are common in poacea and extractable in a crude acid base like in the TLC protocol shouldn't we be seeing it very often in most phalaris samples? Why is it a rare occurrence?

Common but not ubiquitous, perhaps? Their presence in other grasses serves as an indicator of plausibility, not a guarantee that my suggestion is correct. Only a definitive form of chemical analysis would settle this question.
