Event Details

Mariana Antonietta, a Rutherford Fellow in the department, will be presenting her research on staygreen Maize.

The staygreen trait has been presented as a promise to increase yield tolerance to stress in many crops, including maize. Maize breeding has resulted in a delayed senescence staygreen phenotype, and variation in this trait among modern maize hybrids. Is delayed senescence desirable under different stress such as drought, increasing plant densities, and nitrogen deficiencies? May this trait have a penalty over N concentration in grains? These issues together with some ideas regarding assessment of direct N limitations to kernel growth will be presented.

Speaker Mariana Antonietta is an Argentinian visitor to Lancaster Environment Centre the Rutherford Fellowships, Her Fellowship project is focused on assessing genotypic variation for cold tolerance in soybean.
