Ocena efektywności oblotu jabłoni przez pszczołę samotniczą Osmia rufa L. (Apoidea, Megachilidae) w badaniach izolatorowych

Abstract

The investigations of apple pollination efficiency by solitary bee - Osmia tufa L. were carried out from 1987 till 1988. Experiments were made in six test combinations on trees of Red James Grieve variety which were isolated by a nylon screen. A measure of pollination efficiency was percentage of fruit sets and ripe fruits to number of blossoms per tree, mean weight of fruit and number of seeds, and participation of fruit in extra, I and II standard size. It was estimated that solitary bee - Osmia rufa L. was a effective pollinator, better than honey bee on apple.
