Detection of alcohol and tobacco addiction,pections of the entire site appropriate. Two in situ investigations, respectively performed in August 2003 and in November 2003, are outlined. The aim of these surveys was to confirm the success of the work by verifying the growth of the plants and roots. The principal monitored parameters were the

At age 5 years the mean root biomass, for all species combined, was 1.2 kg/plant, and averaged ~23% of total plant biomass. Changes in the allocation of biomass for root and shoot growth appear t

William R. Miller,Ricardo F. Muñozers were more susceptible to uprooting or stem breakage. Nineteen trees werewinched downhill and the force necessary to cause failure was measured. The energy (E.) required to break oruproot a tree was then calculated. Most Silver fir trees failed in the stem and Norway spruce usually failed through

Downhill roots of Norway spruce were largely held in tension when trees were pulled downhill, whereas in Silver fir and European beech, they were held in compression. When trees were pulled uph

Overturning resistance was greatest in heart- and tap-root systems whatever the soil type. However, the heart root system was more resistant on clay-li
