nope! I think that with peroxide is rubbish...
it will probably have a desinfectant effect (if used very fresh), but soon it will end up being only water and oxigen... and I don't think thi sextra oxigen would make a big deal in a well cultivated plant...
as per the secondary metabolites... that's a different story, as it was also part of my PhD
however, mainly in teh interactions animal-plant... yes, also read some articles about the interaction plant-plant but is not my strength...
I give you some other effects which has been proved: some plants, when they are attacked by a fungi, produced some volatile compounds which make the tissues near the infection point to induce a local necrosis. This way, the tissues around the infection point dies and the fungi cannot continue infecting the rest of the plant... unfortunatelly, this is not the case with orchids (at least not the ones I know)
few years ago, this subject was quite in vogue, as Hollywood made a "horror/educational movie" (it was crap, IMO) where plants were reacting against humans contaminating the planet and all this Hollywood green blablabla (attention, I think it is very important to take care of nature and the planet and all this, but I dislike teh sensationalist way Hollywood puts it ion the plate very often!!) The point is that in that movie, plants were communicating via volatile compounds in order to produced some neurotoxins to kill humans..
P.S.- I do not add aspirin to my orchids either
but your question was how to induce the "inmune system" of orchids, and I knew these two threads were here in OB...
