Re: --answer--NPN Identification -- How to properly test

Hi dfams1,

Your question: Ah, thank you very much, that makes sense. How about something like romaine or lettuce though, where there isn't really a "stem" so to speak, do you test the lower part or does it not matter with this sort of veg?

Thanks again

Answer: These also have a stem, but it is the center of the leaf !
