We performed a palynotaxonomy study of pollen morphology and ultrasculpture of nine species of Aeschynomene and 13 species of Ctenodon using light, scanning and electron transmission microscopy, and provided novel data for seven species. Additionally, principal components analysis was performed to elucidate patterns of quantitative data variation between species. Pollen is isopolar (rarely apolar and pantocolporate), small to medium in size, oblate to prolate, 3-zonocolporate or 3-parassyncolporate/3-syncolporate (only in A. americana) with a colporus with margo (the margo was rarely absent), membrane or/and operculum (the operculum was rarely absent), and a rugulate-perforate or nanoreticulate to reticulate sexine. Two pollen types are recognised, one for each genus, based on ultrasculpture variation of the colporus operculum, membrane and margo, and the mesocolpium and apocolpium sexine combined with endoaperture features. The eurypalynous morphology supports the current circumscription of these genera and their phylogenetic relationships.","PeriodicalId":50414,"journal":{"name":"Grana","volume":null,"pages":null},"PeriodicalIF":0.9,"publicationDate":"2022-09-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47940916","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 study area is highly anthropised with cereal, oilseed and forage crops. The samples were obtained sequentially over four apicultural seasons (1999–2000; 2000–2001; 2001–2002; 2002–2003). In each season, one to three honey extractions, corresponding to the initial (I), middle (II) and final (III) productive periods, were made. Pollen assemblage of the honey reflected the study area vegetation. Monofloral honey were exclusively from exotic species, mainly of the dominant crops. Monofloral honey of Lotus corniculatus, Melilotus albus, Medicago sativa, Ammi, Glycine max and ‘clovers’ were obtained. The monofloral honey corresponded to 87.5%, 50% and 66%, respectively, to the honeys obtained in each productive period over the four apicultural seasons. The intra-annual variation of the samples responded to the phenology of the plant species. The inter-annual variations were associated with differential foraging, and the amount of precipitation during the apicultural period. Significant variations were observed when each apiary is compared to itself in different apicultural seasons, and in identical productive periods. Apis mellifera used a fraction of the available flora as nectar resources. The number of plant species visited remained relatively constant throughout the productive periods although it was higher during the apicultural seasons with lower rainfall.","PeriodicalId":50414,"journal":{"name":"Grana","volume":null,"pages":null},"PeriodicalIF":0.9,"publicationDate":"2022-09-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43206556","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}

He was involved in agricultural practice and the building of large infrastructure. Florschütz established centres of pollen analysis at the universities in Wageningen (1924) and Utrecht (1928), was appointed professor in Leiden (1948) and after retirement founded a chair in pollen analysis in Nijmegen (1960). The botanical institute in Utrecht was Florschütz’ alma mater where he supervised students over two decades. Since 1947 Florschütz trained micropalaeontologists how to use fossil pollen as a biostratigraphical tool in oil industry. He inspired Jonker in Utrecht and Zagwijn in Leiden. Several of his students focused on tropical areas and used applied and academic pollen analysis to explore tropical ecosystems, such as Polak (1930s) and Muller (1950s) in southeast Asia, Van Zinderen Bakker (1950s) in southern Africa, Van der Hammen (1950s) in northern South America, Van Zeist and Bottema (1960s) in the Middle East. He stimulated Shell to be a pioneer in using pollen-based stratigraphy in oil exploration in the tropics. In the late 1940s and 1950s biostratigraphers Germeraad, Hopping, Kuyl, Muller and Waterbolk studied samples from the Caribbean, Nigeria and British Borneo in Shell’s Pollen Laboratories in Maracaibo (Venezuela) and in The Hague. In 1944 ‘pollen analysis’ was renamed ‘palynology’ for good reasons. Laboratory practice in applied research developed differently from academic palynology leading to a hybrid research field. Implications are briefly discussed.","PeriodicalId":50414,"journal":{"name":"Grana","volume":null,"pages":null},"PeriodicalIF":0.9,"publicationDate":"2022-07-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47487181","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}

All the pollen grains are trizonocolpate; however, some taxa were observed to have also hexacolpate grains along with trizonocolpate ones. The pollen grains are large, suboblate, less often oblate spheroidal in shape. Distyly is predominantly present in the section, except for homostylous species Linum nodiflorum L. All the studied distylous taxa have dimorphic pollen grains. In short-styled floral morphs, the exine has monomorphic processes, gemmae, which at the top have a ring of marginal papillae, with or without prominent central papilla. In long-styled floral morphs and in homostylous morph, the exine is dimorphic and has two types of processes: bacula, smaller in diameter, ending in a central microechinus, and clavae, larger in diameter with a central microechinus ending into lobes or a ring of scabrae at the margins. In the studied distylous species, the pollen of short-styled morphs is larger than that of the long-styled morphs. Based on the morphometric data, the principal component analysis has grouped these two morphs separately; with the homostylous one, although with dimorphic exine, nested within the short-styled morphs. This could be considered as evidence supporting the loss of heterostyly in homostylous Linum.","PeriodicalId":50414,"journal":{"name":"Grana","volume":null,"pages":null},"PeriodicalIF":0.9,"publicationDate":"2022-06-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41602412","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}
