The present study aimed to investigate the skin prick test (SPT) reactivity to the pollen of Conocarpus erectus trees and to find the association between the indoor and outdoor aeroallergens in the patients. In the present case series multicentre study, 104 patients with respiratory allergies such as allergic rhinitis and asthma who were referred to the Bushehr University allergy clinic participated. The SPT was applied by using the extract of Conocarpus erectus pollen and the other allergens to determine the patients’ reactivity. The frequency of positive sensitivity to Conocarpus erectus pollen was 61 (58.6%) and it was 62.5%, 55.7%, and 53.8% for the tree pollen allergens Citrus X Sinensis, Morus rubra, and Phoenix dactylifera, respectively. In addition, the maximum frequency of sensitivity to other aeroallergens was with house dust mite (HDM) (78.8%), Salsola kali; 71.2%), and cockroach (71.2%). The maximum frequency of reactivity to food allergens was with egg yolk (37.6%), shrimp (37%), and beef (34.6%). This study concludes that the frequency of sensitivity to Conocarpus erectus pollen was high and similar to the pollen allergens of other trees that are widely cultivated in southern Iran. Green spaces are the key element of urban management, and the interaction between citizens and the environment, as well as promoting human health are very effective. Therefore, the lack of planning in urban populations in the choice of ornamental species can be a triggering factor, especially in patients with respiratory allergies.","PeriodicalId":50414,"journal":{"name":"Grana","volume":null,"pages":null},"PeriodicalIF":0.9,"publicationDate":"2022-01-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49617782","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The pollen grains were acetolysed, measured, described qualitatively and illustrated under light microscopy and scanning electron microscopy (not acetolysed pollen grains).

The studied species showed differences on the pollen units (monads or polyads) and variations in number and distribution of pollen grains in the polyads. Three pollen types were observed: type I, pollen grains in monads (Plathymenia reticulata); type II, polyads with one tapered end (drop shape – Calliandra parviflora); type III, polyads with uniform ends with asymmetrically distributed pollen grains (Stryphnodendron species); or symmetrically (with 16 or 20 pollen grains in Acacia plumosa, Albizia niopoides, Anadenanthera species, Inga marginata, Inga vera and Senegalia species and more than 20 pollen grains in Enterolobium contortisiliquum, Inga edulis and Inga sessilis).

We have conducted a comparative pollen morphological study of five populations of the two putative species to investigate this question. Pollen morphological characteristics were observed with scanning and transmission electron microscopy. The pollen characteristics of all five populations were similar. All populations dispersed pollen as the monad and the pollen grain shape were either spheroidal or sub-spheroidal and approximately 12 to 18 µm in diameter, falling in the small grain category. In all five populations, the pollen grains were iso-polar and radio-symmetrical, with tri-colporate apertures. Additionally, pollen surface sculpture patterns of all populations were semi-tectate and reticulate. As a result, the two putative species differed in that the pollen grains of K. palmata were smaller, and their endexine slightly thicker, than those of K. koreana. Despite these differences, we conclude that the similar pollen morphology of all the populations does not support separating them into two independent species. However, different species of angiosperms often have similar pollen morphology. Therefore, we suggest that the genus should be considered to consist of these two independent species unless further morphological or molecular evidence to the contrary is forthcoming.","PeriodicalId":50414,"journal":{"name":"Grana","volume":null,"pages":null},"PeriodicalIF":0.9,"publicationDate":"2021-12-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48431323","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Pollen specimens were obtained from herbaria, treated by the acetolysis method, measured, photographed, and described using light and scanning electron microscopy. In the analysed species, pollen grains were isopolar or heteropolar, medium-sized, tricolporate, oblate spheroidal to subprolate. Ornamentation patterns differed among species, with examples of bireticulate, microreticulate, perforate, reticulate, and rugulate sexine. These characters were used for the development of a pollen key to the genera.
