Chemotype, maternal genotype, or field neighbors: what influences performance and resource allocation in a perennial plant species the most?
Article in Oecologia, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Plants have to allocate resources into their growth and reproduction but also in phytochemicals used in interactions with their environment. Some species display an extraordinarily high diversity of such phytochemicals, called chemodiversity. In stands with different neighbors, plot chemodiversity may be even higher and provide associational resistance. Little is known about trade-offs in investment into growth and reproduction versus chemodiversity in plant individuals growing in chemically different neighborhoods.We investigated such trade-offs using the perennial Tanacetum vulgare, which shows differences in leaf terpenoid composition, forming distinct chemotypes. We planted plots consisting of five plants of one of five chemotypes (homogenous neighborhoods) and plots consisting of five different chemotypes (heterogenous) in a field. Plants within each block were offspring from different mother plants (here called maternal genotypes). Over 2 years, plant performance traits related to growth and reproduction were recorded and the leaf terpenoid profiles were measured once. Depending on the chemotype, plants had significantly different chances of flowering. Plants in heterogenous plots produced a higher maximum number of flower heads than those in homogenous plots. The maternal genotype explained some of the variance in growth- and reproduction-related traits. No significant correlations were found between the terpenoid functional Hill diversity (FHD) or its components (terpenoid richness, evenness, and structural disparity) and growth- and reproduction-related plant traits. Our results suggest that both the terpenoid chemotype of an individual and the chemodiversity of its neighborhood can impact reproduction-related traits, possibly driven by interactions of the individual with the environment and different resource allocation.
