Taxon: sunflower ✕

A claim can belong to several research areas, so group counts add up to more than the total.

Taxon groups are the verbatim names found in the abstracts (case-insensitive), not normalised: maize, corn and Zea mays are separate groups here. The Organism view merges them through NCBI Taxonomy.

Other claims from this paper (9)

Association Plant Pb content rose with Pb concentration in the nutrient medium.
Observation Pb accumulation was greater in roots than stems and leaves.
Intervention effect High leaf Pb concentration reduced plant dry mass and height.
Intervention effect Lead treatment markedly reduced chlorophyll content.
Intervention effect Lead treatment caused smaller decreases in photosynthetic oxygen evaluation and PSII efficiency at low light.
Mechanism The authors interpret lead as reducing rather than destroying the photosynthetic apparatus.
Intervention effect The highest Pb concentration decreased efficiency of PSll electron transport at saturating PFD.
Intervention effect The highest Pb concentration significantly affected nonphotochemical fluorescence quenching.
Mechanism The authors infer increased thylakoid proton gradient and decreased photophosphorylation under highest Pb.
