Flower Production, Headspace Volatiles, Pollen Nutrients, and Florivory in Tanacetum vulgare Chemotypes

Floral volatiles and reward traits are major drivers for the behavior of mutualistic as well antagonistic flower visitors, i.e., pollinators florivores. These floral differ tremendously between species, but intraspecific differences their consequences on organism interactions remain largely unknown. volatile compounds, such terpenoids, function cues to advertise rewards pollinators, should at same time also repel The composition, e.g., protein lipid contents in pollen, differs individuals distinct plant families. Whether nutritional value within species is linked chemotypes, which pattern specialized metabolites, has yet not been investigated. In present study, we compared Tanacetum vulgare plants five terpenoid chemotypes with regard production, headspace volatiles, pollen macronutrient content, attractiveness florivorous beetles. Our analyses revealed remarkable amount diameter heads, duration bloom period, quality. composition pollen-producing mature flowers, premature was correlated that leaves individual. For two beetles discriminated scent heads preferred latter. semi-field experiments, abundance tissue miners differed T. chemotypes. Moreover, environment affected choice were more abundant homogenous plots composed one single chemotype than different neighboring conclusion, metabolic quality varied a extend , intra-individually ontogeny. We found evidence trade-off content per-plant-level. study highlights susceptible florivory less attacked when they grow neighborhood other thus gain benefit from high overall chemodiversity.
