Seedlings STANISLAWMALEKandJAN GRESZTA Department ofForest Ecology, Forest Faculty, AgriculturalAcademy ofKrak6w, AI. 29-go Listopada 46, pL-31425 Krak6w, Poland ReceivedJune 26, 1995 .Accepted October 8, 1995 Summary The purpose ofthe present experimentwas to describe the influence ofvarious methods ofmineral fer-tilization:NK into leaves (Florovit),NPK onto soil (Fruktus 2) and liming (dolomite magnesium) on the development ofFagus sylvatica L. seedlings subject to the influence ofsimulated acid rains ofpH 2.5, 3.0, 3.5,4.0, 4.5. As a result of the carried out analysis of the correlation coefficient a reciprocal high correlation was found between particular parameters ofgrowth of Fagus sylvatica L. seedlings i.e. ofthe diameter ofroot nect, root mass, total mass of: seedlings, leaves, main shoots, lateral shoots, ligneous parts, overground parts, as well as of total length of lateral shoots. Whereas no high correlation was observed between the above mentioned parametersand a total heigth ofthe seedling. The obtained results ofthe analysis ofchanges in biometric characteristics ofFagus sylvatica L. seedlings showed, that the best development was achieved at pH 4.5, whereas their weakest development was observed at 2.5. The analysis showed the decrease in values of analysed characteristic together with the increase in acidity ofaqueous solutions. The first and second and third year ofthe experiment for Fagus sylvatica L. showed that kind of fertili-zation did not effect positively the increase in values ofthe analyzed biometrical feature-total height of seedling comparing with those of control plots. The significant improvement of total height of seedling was noticedon control plotwithpH 3.5 in relation topH 2.5 on control plot in first year.The best incre-ment oftotal height ofseedlingwas noticed forpH 3.5 for each year. The third yearofthe experimentshowed that using fertilization: Ca+Mg onto soil,NK into leaves and NPKonto soil it is possible to restrict the unfavourable influenceof«acid rains» on total mass ofFagus syl-vatica L. seedling. The best significant increment of this biometrical feature was observed on pH 4.0. When one wants to restrict the unfavourable influence of«acid rains» on analyzed total mass ofseedlings withinpH 2.5-4.5 it is possible to choose optimalyonefrom three applied fertilizing variants.
