Grana是一本國際孢粉學和空氣生物學雜志。Grana，最初以Grana Palynologica的名義出版，由Gunnar Erdtman教授于1954年創建。它是由斯堪的納維亞孢粉學學院(CPS)主辦，與國際空氣生物學協會(IAA)合作出版的。主要發表真核生物花粉粒和孢子的形態、超微結構及其在植物分類學、生態學、植物地理學、古植物學等方面的重要意義等方面的原創論文。空氣生物學包括研究空氣中的生物顆粒，如花粉、孢子等，以及它們的發射、散布和最終沉積。這些顆粒在醫學(過敏學)和植物病理學中的意義是特別有趣的。所有提交的稿件都要經過編輯的初步評估，如果發現適合進一步考慮，還要經過獨立的、匿名的專家評審。所有的同行評審都是單盲的，通過ScholarOne手稿在線提交。

Grana is an international journal of palynology and aerobiology. Grana, originally published as Grana Palynologica, was founded in 1954 by Professor Gunnar Erdtman. It is published under the auspices of the Scandinavian Palynological Collegium (CPS) in affiliation with the International Association for Aerobiology (IAA). Grana publishes original papers, mainly on ontogony (morphology, and ultrastructure of pollen grains and spores of Eucaryota and their importance for plant taxonomy, ecology, phytogeography, paleobotany, etc.) and aerobiology. Aerobiology involves studies of airborne biological particles, such as pollen, spores, etc., and their launching, dispersal and final deposition. The significance of these particles in medicine (allergology) and plant pathology is of particular interest. All submitted manuscripts are subject to initial appraisal by the Editors, and, if found suitable for further consideration, to peer review by independent, anonymous expert referees. All peer review is single blind and submission is online via ScholarOne Manuscripts.
