On the Divergence of Some Physiological Properties of Different Provenances of Silver Fir (Abies pectinata DC) in Yugoslavia Summary With reference to the fact that climatic changes cause physiological abnormalities of silver fir, in its water balance particularly, the consequence of which is the actual rapidly dying-back of this species, 20 provenances from the territory of Yugoslavia were investigated. The following characteristics were studied: dry bio- mass weight, reaction of the increment on climatic changes, water capacity, transpiration activity and resorption capacity. Considerable differences among individual provenances and the advantage of those on eastern localities have been established. Remarkable differences between soils with limestone (calcium carbonate) and without it have been found, as well. Figures show, according to provenances: Fig. 1. Specific water capacity of 2, 3 and 4 years old fir trees Fig. 2. Specific water capacity of needles of 2, 3 and 4 years old far trees Provenances are arranged from left to right according to geographical longitude |
