Kurm, M. | Kiviste, A. (Estonian Agricultural Univ., Tartu (Estonia). Forest Research Institute)
Altogether, 1003 grafts were studied in Pauska seed orchard in South-Estonia from 1988 to 1993. The descendants of 4 clones and 5 different kinds of fertilizers (N, P, K, NPK and the control group) were used in the research. The effect of three factors (fertilization, clone and year) on different characteristics of spruce grafts were studied. The general linear method (the GLM procedure) of the SAS software package was used to find out the dependence of spruce graft variables. Apart from the morphological features and the content of nutrients in needles as well as in seeds, the quantities and qualities of cone and seed crop were observed
