The paper presents the results of research on the genetic variability in the growth characteristics and plasticity of Polish provenances of Norway spruce, tested on thirty plots established in Europe and Canada in the IUFRO 1972 provenance experiment. Special consideration was devoted to the plots in Poland, especially in Knyszyn. The variability in the growth and quality characteristics of the provenances,...
The paper presents the results of research concerning the genetic variation in the growth traits and phenotypic plasticity of Norway spruce populations from the Silesian Beskid Mts and compares them with those of twenty Polish spruce provenances planted on thirty plots established in Europe and Canada in the IUFRO 1972 provenance experiment. The Silesian Beskid spruce is represented by six populations...
W pracy podjęto próbę wyznaczania parametrów plastycznego płynięcia wybranych sypkich surowców spożywczych charakteryzujących się dużym stopniem rozdrobnienia i dużą podatnością na zagęszczanie. Pomiary przeprowadzano w aparacie bezpośredniego ścinania Jenike'go. Zastosowana procedura wielokrotnego ścinania umożliwiała wykonanie od 4 do 7 ścięć tej samej próbki przy coraz mniejszych wartościach naprężenia...
