Description
  • V letech 1998 - 2000 bylo pěstováno sedm odrůd pohanky seté ve dvou variantách hnojení (0 a 50 kg N.ha-1). Cílem pokusu bylo posoudit vliv odrůdy, hnojení a ročníku na tvorbu výnosových prvků pohanky seté a vztahy mezi jednotlivými prvky. Mezi jednotlivými výnosovými prvky pohanky seté existuje kompenzační schopnost. Zvýšení hustoty porostu redukuje větvení jednotlivých rostlin i počet květenství na rostlině. Počet květů na hroznu je ovlivněn průměrnou denní teplotou v době od butonizace do počátku květu. Počet nažek na rostlině je negativně ovlivněn srážkami v době květu. Velký počet květů snižuje nasazení semen a negativně tak ovlivňuje i výnos. Vysoký počet nažek na rostlině je spojen s jejich nižší hmotností. Vznik prázdných nažek je mimo jiné výsledkem citlivosti rostliny k teplotním podmínkám v období zrání nažek. Hlavním prvkem určujícím výnos pohanky je počet plných nažek na rostlině. (cs)
  • Seven varieties of common buckwheat were tested in field experiments under two levels of nitrogen fertilisation (0 and 50 kg N ha-1) during the period 1998-2000. The objective of the experiments was to evaluate the influence of varieties, fertilisation and year on the formation of yield components in common buckwheat and to evaluate the relationships between the individual components. As was observed, a compensatory ability exists among the particular yield components. An increase in stand density reduces branching and the number of inflorescences per plant. The number of flowers in the raceme is influenced by the mean day temperature during the period from flower bud formation to the beginning of flowering. Rainfall during flowering negatively influenced the number of achenes per plant. The high number of flowers reduced seed setting and negatively influenced the yield due to competition for assimilates. The high number of achenes per plant was linked to lower weight. The occurrence of empty achenes
