Abstract
This report describes a study that was made to examine how the production, the period of production and the distribution of biomass in a clone of Salix viminalis were affected by shortage of water and nutrients. A field study was performed in which one third of the plants were cultivated under conditions that caused nutrient stress, one third of the plants received too little water and one third of the plants were cultivated under optimal conditions. The experiment lasted for four years including a harvest of the shoots during the autumn of the third year. During the period of the experiment the root activity (measured as the number of roots) and the growth of the shoots were measured every second week. The proportion between biomass invested in the roots and in the shoots was measured when plants were harvested at five occasions each year. Stem production during the third growing season reached 12 tonnes dry matter per hectare and year under non-limiting water and nutrient conditions. Shortage of nutrients and water reduced the rate of stem production to 5 and 2 tonnes dry matter per hectare and year respectively. The root activity did not differ between the treatments. The plants
