Fengze Sun; Yahui Wang; Genzhong Liu; et al. Vegetable Research 2024. doi:10.48130/vegres-0024-0017

Other claims from this paper (9)

Intervention effect Tomato plants treated with 50-150 mM NaCl showed an early flowering phenotype relative to the control.
Intervention effect Tomato plants treated with 50-150 mM NaCl produced smaller flowers relative to the control.
Intervention effect The SFT gene was upregulated under salt stress in tomato, as shown by RT-qPCR.

Association Ear bracts had higher PSII quantum yield than leaves.
Intervention effect Removing grains immediately before measurement slightly reduced PSII quantum yield.
Association Even after grain removal, PSII quantum yield remained much higher in ear bracts than in flag leaves.
Mechanism The authors infer that grain-respired CO2 may help maintain high ear photochemical efficiency.
