Abstract
In Poland we have the several year hop plantations that need a quick adaptation of the cultivation structure to new requirements from the European brewery industry. Planting of hop plantations using traditional methods („bud cuttings” or rooted cuttings) requires as long as a three- year period to get the maximum yielding. This fact makes the supply of the hop market unstable, and is the main factor of farmers, financial losses. Currently, using at the IUNG-PIB of a greenhouse method of cuttings production by vegetative propagation from green parts and the in vitro method makes possible to develop a technology, which would allow shortening of the time needed to get maximum yields. The field experiment using a split-plot method was carried out in four replications at the IUNG Kępa Experimental Station in 2003–2006, after removing the old plants in the autumn 2002. A two-factorial trial (cuttings, time of planting) included with three kinds of cuttings of the bitter variety IUNGA (bud cutting, rooted cuttings, potted cuttings in vitro) and three dates of planting (autumn, spring, summer). The size of plot was 112.5 m² (24 plots × 24 cuttings). Yield of hop cones from the plot was estimated in kilos per hectare. Moreover, the content of alpha acids (technological element of chemical quality of hop cones) was determined. The results of obtained confirmed the possibility of reaching a relatively high yield as early as the first year after planting from cuttings propagated vegetative in vitro. No essential differences between the experimental variants in the alpha acid content of cones were found.
