Production ecology and physiology of agricultural crops

Weihportatt-187x300Major research activities focus on the production ecology and physiology of agricultural crops – mainly perennial energy crops grown on agricultural land (Salix) and cereals (barley and wheat) – and the genetic basis of production traits. The effect of agriculture on the environment (e.g. biodiversity) is another research interest. The research team currently consists of myself, an Assistant Professor (Dr. G. Vico) and two PhD students (L. Asplund, F. Pourazari), and is part of the crop physiology group at the Department of Crop Production Ecology. More information regarding current and past projects is found at www.slu.se/weih.
