Density of honey bees (Apis mellifera L.) on rows of the self-pollinated sunflower line 2607 in seed production of Albena hybrid


, : Density of honey bees (Apis mellifera L.) on rows of the self-pollinated sunflower line 2607 in seed production of Albena hybrid. Helia 17(21): 53-56

Studies on the production of hybrid sunflower seed were carried out in 1989-91 in Dobroudja, Bulgaria, in order to determine the effects of the spacing of the female line rows (line 2607) from the male line row on the density of Apis mellifera on the female line rows.

The repercussions of concurrent foraging by honey bee (Apis mellifera) and non-Apis bee populations on cross-pollination and seed set in hybrid sunflowers (Helianthus annuus) was investigated. The amount of sunflower pollen on the bodies of honey...
