Effect of increased nitrogen depositions and drought stress on the development of Scots pine (Pinus sylvestris L.) I. Response of above-ground parts

Popis výsledku v původním jazyce

Effect of drought stress, stress by increased nitrogen depositions and combined effect of the two stress factors on the growth of Scots pine (Pinus sylvestris L.) were studied in two experimental series in the period 1994-1997. The drought stress was induced by reduction of atmospheric precipitations by 60%, the increased nitrogen depositions were simulated by repeated applications of ammonium sulphate at a dose corresponding to 100 kg N.ha-1.year-1. All stress factors under study impacted the height increment of above-ground part, length and colour of needles, number of buds in the terminal rosette, content of free aminoacids and the ratio of elements in dry weight of assimilatory tissue. Drought acted as a stress factor stronger than the nitrogen depositions themselves. The strongest impact was recorded in the simultaneous influence of the stress factors.
