Studies were made on the anatomical structure of the nectaries in the flowers of 21 paprika varieties and on the nectar-producing ability of 5 of these varieties. The external morphology of the nectaries was observed with the aid of a stereomicroscope, the apicultural values were clarified by nectar production measurements on the 5 varieties most frequently visited by bees. It was found that the nectaries are differentiated from the carpella and form a ring round the ovary (this is generally characteristic of the Solanaceae). The colour of the automorphous gland is yellow, white, green or various shades of these. Among the epidermal cells, single nectar stomata can be seen, which transport the nectar to the surface. Small-celled glandular tissue is to be found below the epiderm, with a cell row number ranging from 3-4 to 10-12, leading to differenences in size and production characteristic of the variety. The size of the nectaries conforms with that of the flower. Among the varieties examined for nectar production, Szegedi csipossegmentes 200 produced 3 mg nectar a day, with a sugar content of 22 o/o or 0.66 mg. Cecei 110 had a nectar production of 1.9 mg/daz, with a sugar content of 21 o/o or 0.39 mg. Cseresznye alaku produced 1.9 mg nectar a day, Bocskor 0.44 mg and Feferoni 0.3 mg. Szegedi csipossegmentes produces more nectar than acacia flowers.
