The science behind improving taste of grown products is mostly secret information companies will not share, they have to make money.In Switzerland, they say the original "Erdbeer" strain (German for "strawberry") was found growing in the middle of a huge strawberry field. Or maybe the story was made up to account for the berry aroma. Do you think maybe that's how it happened? Is this a dumb question? What's the science on how weed gets its aroma?
Try to find out what is in the products being sold for the same purpose and I think we are close. BUT, I also believe there is way more th=at we are just starting to understand as science.
There are so many factors that modify perceived smell and taste. I say perceived because many small changes are not noticed. What is in the soil is Switzerland that makes your tomatoes different than what I grow? Here, where I live, corn is not very good. 200 miles away what they grow is spectacular.
The soil is different. NPK, pH, microbes, fungus, drainage, microclimate? Yes lots of science to make stuff grow better where it is. Science to explain why their corn is better than mine and what can I do about it? NOT that I am aware. My guess on this question is simple economics. Mostly subtle changes in results at a high cost equals zero scientific study. A little here and there but the big players are not interested until there is lots of money.
Perhaps we can be pioneers here. Because weed is a very high value produce even subtle changes could make could make the buds more valuable to justify the added cost.
I think there MUST be some grower that also has access to an apple orchard and 100's of gallons of apple juice and will feed it to their plants then say, "EURICA!"
The strain in the middle of the field? Perhaps the strawberries roots exude a particular enzyme that acts in symbiosis with the surrounding plants. Or maybe the surrounding plants make direct use of the same?
Everything can have an affect on everything else. Everything is Everything
