Abstract CONTEXT OR PROBLEM Forage maize is a central pillar of dairy cow feeding in France, directly influencing milk production. Drought significantly affects both yield and digestibility, which are key parameters required for hybrid registration purposes.

Water and nutrients are two main determinants of wheat yield, which vital for maintaining high crop yields. In the present study, effects water phosphate fertilization on photosynthetic parameters, productivity use efficiency were investigated. Five dryland cultivars from 1940s to 2010s that widely cultivated in Shaanxi Province, China, used. Experiments conducted 2019 2022 using irrigation levels (normal rainfall no precipitation after reviving stage) phosphorus application (0 100 kg ha

The plasticity elongation of mesocotyl (MES) and coleoptile (COL) largely determines the morphology maize seedlings under abiotic stresses. profilin (PRF) proteins play a pivotal role in cytoskeleton dynamics plant development via regulating actin polymerization. However, little is known about whether how expression
