Photosynthetic and antioxidative strategies of flag leaf maturation and its impact to grain yield of two field-grown wheat varieties

Photosynthesis is the most important source of dry matter production directly influencing grain filling in wheat. Croatian winter wheat varieties, ‘Vulkan’ and ‘Golubica’ have similar genetic yield potential but in previous years ‘Golubica’ failed to achieve it. In order to find reasons of that, we evaluated photosynthetic (JIP test) and oxidative pathways (antioxidative enzymes and non-enzymatic components) in flag leaves of both wheat...
