If you are wanting to pursue a career in science, you will need to start reading papers - this is the only way to become familiar with what has happened in your field and what is currently happening. I would suggest starting with a reading a recent review on your topic, these are often the most accessible way of getting into the literature, as they summarize what is known about a (subset of) your field. Just be aware that usually the reviews are trying to sell a particular view point or are just something that (often a student) has written to get themselves familiar with the field, and so may not be complete in covering all the literature.
From your post it looks like you have two avenues - either you aim to publish in a botanical/plant biology journal or you aim for a ethno-botanical journal. I would think that general plant biology is probably more widely read and so more likely to boost your publishing indices (e.g. H factor) and name recognition.
Just do a google search for "plant journals" (or "ethnobotany journals") and see what comes up. You can also try searches such as "plant journal and seed dormance" - have a look at the content in a couple of the journals and see if you and your supervisor think they publish research similar to what you have done, and so might be willing to publish your research, and then try to write the paper in they same style as the papers within and submit it. All journals have submission guidelines for the author somewhere on the journal's website.
