I am researching reproduction of Salvia officinalis, I found some knowledge on Lamiaceae but it's not enough. Do you have any article please share with me.
Maybe It's hard for you to find published articles on pollination of the specific plant species Salvia officinalis. But it is easy to download papers on pollination of the other species belonging to genus of Salvia, like Ohashi Evolution 2002 and ClaBen-Bockhoff et al. Plant biology 2003, etc. I think these papaers may give you some enlightenment.
We have published a paper on the pollination biology of Salvia virgata and S. verticillata. You may interest it. I attached it FLIES AS POLLINATORS OF MELITTOPHILOUS SALVIA SPECIES (LAMIACEAE). American Journal of Botany.
