Abstract
The studies on the period and abundance of blooming, flower development, as well as nectar productivity of two cultivars of Lonicera kamtschatica (Sevast.) Pojark. were carried out in 2004-2005 in Lublin. The investigated plants bloomed between the third decade of April and the middle of May. The life span of protogynous flowers was about 4-5 days. The mean amount of sugars secreted by 10 flowers of the examined cultivars ranged from 17.77 mg to 28.31 mg. The sugars yield amounted to from 44.08 to 67.81 kg.ha-1. Flowers of the investigated plants were a good nectar source for honeybees and bumblebees.
