THE INFLUENCE OF SUBSTRATE PH ON GROWTH OF ROCKY MOUNTAIN JUNIPER (JUNIPERUS SCOPULORUM) ‘BLUE ARROW’ IN CONTAINER CULTIVATION

Stanisława Korszun, Grzegorz Bykowski

 

ABSTRACT



The experiment on cultivation of the Rocky Mountain juniper ‘Blue Arrow’ variety in containers was conducted in years 2000-2002 in an unheated glasshouse. The plants were cultivated in a substrate composed of a mixture of high moor peat and frittered, composted pine bark in volume ratio 1:1, with a different substrate pH in H2O: 4.5; 5.0; 5.5; 6.0; 6.5. In order to obtain substrate pH in H2O 7.2; 20% mineral soil was added to pine bark (40%) and high moor peat (40%). During vegetation season biometric measurements were performed i.e. the height of plants and length of lateral shoots [cm] were measured and the number of lateral shoots was counted. Also the pH of cultivation substrate was measured. When the experiment was completed, fresh root weight and the weight of fresh above-ground part of plants were measured. Before and after completion of the experiment, chemical analysis of the cultivation substrate was performed for each combination to estimate the content of m

Key words: Rocky Mountain juniper, Juniperus scopulorum Sarg., ‘Blue Arrow’, growing substrate pH, container cultivation..
