o:7305 KORELACIONA VEZA IZMEĐU POJEDINIH BILJNIH ORGANA OBIČNE SMRČE (PICEA ABIES KARST.) GAJENIH NA RAZLIČITlM SUPSTRATIMA CORRELATION LINK BETWEEN SOME PLANT ORGANS OF NORWAY SPRUCE (PICEA ABIES KARST.) GROWN ON DIFFERENT SUBSTRATA sr The seedlings of Norway spruce (Picea abies Karst.) were grown on a tew variants of substrata, consisting of different volume ratios of the following components: Russian peat, beech humus, spruce humus, soil into which buckwheat was previously plowed, ordinary nursery soil and inorganic small particles of mother rock (grus in Serbo-Croatian). On a sample of 909 seedlings from two experiments, aged 2 + 0, the correlation link was studied between some plant organs, dried at 105°C. Between dry root mass (X1) and adry overground part of the plat without needles (X2), then between dry root mass (X1) and dry mass of needles (H3), as well as between dry overground part of the plant without needles (X2) and dry mass of needles (Xs) exists an expressed or full linear correlation link of positive sign, with corresponding regression coefficients which also vary in a certain dregree, depending on test variants. A certain variation of correlation coefficients of plant organs, depending on test variants, may be explained to a certain degree by differences of physical- chemical characteristics of substrata of corresponding test variants. 2025-03-21T11:01:35.443Z 44 yes 46 Ljubisav Marković 46 Danica Marković application/pdf 6965965 https://unilib.phaidrabg.rs/o:7305 no yes 1 70 92000001 1988 71A07 Zbornik radova Instituta za šumarstvo 87 101 Institut za šumarstvo 1988
