Abstract

Influence of cultivar and type of cuttings on rooting percentage and root length in northern white cedar (Thuja occidentalis) was investigated. Two cultivars ('Columna' and 'Smaragd') with three types of cuttings (simple, heel and mallet cuttings) were included in the trial. Rooting percentage was significantly influenced by the cultivar and type of cuttings while the root length was significantly influenced by the type of cuttings. Higher average percentage of rooted cuttings was recorded in cultivar 'Smaragd' compared to 'Columna' cultivar. Average percentage of rooted cuttings was higher in both cultivars with the use of mallet and simple cuttings, compared to heel cuttings. Average root length of mallet cuttings was significantly longer than average root length of both simple and heel cuttings, independently of cultivar. In order to achieve better rooting, in the nursery production of both cultivars, use of mallet cuttings is recommended.
