“…The length of the stamens in the flowers of the biennial and repeated fruiting cultivars examined in the present study ranged from 3.5 ('Laszka') to 4.8 mm ('Glen Ample') and was similar to the values (3-6.9 mm) reported in R. clementis, R. ideaus 'Polka', R. moorei, and R. nebulosus [75,77,79]. At the same time, these values were higher than the range of 1.0-3.01 mm measured in the flowers of R. chrysophyllus, R. ellipticus, R. fraxinifolius, R. lineatus, R. macilentus, R. moluccanus, R. rosifolius, R. royenii 'Hispidus', and R. sengorensis [77,[80][81][82].…”

“…In the present study, the number of stamens in the flowers of the biennial and repeated fruiting R. idaeus cultivars was within the range of 102 ('Glen Ample')-113 ('Laszka') and 93 ('Polka')-112 ('Polana'), respectively. The number was higher (except 'Polka' and 'Glen Ample') than the values of this parameter reported by other authors for the following cultivars of red raspberry: 'Polka' (83)(84)(85)(86)(87)(88) and [74,75]. The average number of stamens in a single flower of the six raspberry cultivars examined Explanation: present study (PS).…”

Poland is the largest European Union producer of Rubus idaeus. This species provides insects with nectar and pollen from June to September. The rationale behind the present research is the increasing commercial production and the use of food attractants for pollinators increasing fruit yields. The intensive search for phytochemicals applicable in industry and phytotherapy together with the unavailability of data on anther epidermis and endothecium structure justify undertaking these investigations. The pollen mass, the content of elements, protein, and fat, as well as the composition of amino acids and fatty acids in the pollen of six R. idaeus cultivars were compared. In terms of pollen production, the cultivars ranked as follows: ’Pokusa’ < ‘Polana’ < ‘Glen Ample’ < ‘Polka’ < ‘Radziejowa’ < ‘Laszka’. The protein content (26–31%) in the pollen indicates its good quality and high attractiveness. Exogenous amino acids, including those with dietary importance, constituted a substantial proportion (33–39%). The content of MUFAs and PUFAs was 32–47% and 3.7–9.1%, respectively. The presence of elements that determine the nutritional value and proper development of pollen was detected in the mineral composition of the exine. The data on the epidermis and endothecium structure provide new information about the micromorphology, anatomy, ultrastructure of and generative organs and auxiliary criteria in the taxonomy of related species.
