Different grasses are being measured for drought tolerance at Aarhus University, Denmark, as described at http://grassmargins.com/news_items/71. The aim is to identify crops that have potential use for a high and stable biomass production under drought stress conditions.
The drought period has been going on for six weeks and the grasses are visibly affected by the drought treatment (Figure 1 and 2).

Figure 2Phalaris arundinacea cv. Bamse, drought treated (bottom) and control (top).
The measurements of plant physiological and yield responses to drought are ongoing (Figure 3), and the results will be presented in September at the “Perennial Biomass Crops for a Resource Constrained World“ conference.
