The anatomical and histochemical descriptions were made on 20 randomly selected seeds, which were processed using standard protocols for scanning electron and light microscopy studies and to obtain permanent and semi-permanent slides. For germination study 210 seeds were sown in Petri dishes on agar, using six replicas; weight and size were obtained using 50 seeds randomly selected. The results show that the seed coat is formed by a non-striated cuticle with pectics and proteinaceous substances. The exotesta occupies 6.8% of the total volume of the seed, it has lignified-suberized and protein-containing anticline walls, forming U-type undulations with protrusions. The endotegmen is suberized and an embryonic membrane lacking ergastic contents surrounds the embryo. The endosperm is confined to a dorsal ridge. The embryo is globose, with two cotyledonous protrusions, and the hypocotyl assumes the reserve function with a \"globoid crystals/protein bodies\" association. The micropylar hilum region is small and oval, filled with parenchyma. Germination started on day 5th and ended on day 29 th , with a mean germination time on day 8.9. The final germination percentage was 74.29%. The age, seed size, crystal and protein reserve as well as germination percentage of the M. parkinsonii suggest a potential orthodox or intermediate behavior to form soil seed banks in a desert habitat.","PeriodicalId":30046,"journal":{"name":"Polibotanica","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-01-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44377510","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The results indicated that the Phaseolus genus is a monophyletic group that is subdivided into two main lineages: a first clade formed by P. pluriflorus , P. esperanzae , P. pedicellatus , P. microcarpus , P. glabellus , P. oligospermus , P. gladiolatus , P. zimapanensis , and P. albiviolaceus ; and a second clade that includes P. filiformis , P. acutifolius , P. vulgaris , P. coccineus , P. macvaughii , P. leptostachyus , P. lunatus , P. maculatus , P. maculatifolius , and P. rotundatus . The topology of the subclades was in general agreement with the topology for Phaseolus recognized to date. Of the species not previously studied, P. albiviolaceus belongs to the Pedicellatus group according to its morphology, but here it was located at Tuerckheimii group; P. maculatifolius and P. rotundatus were included in the Polystachios group.

The presence of symptoms was found at the third week of development of the infected fruits.

El objetivo fue comparar la abundancia, riqueza y diversidad de arvenses presentes en monocultivos de maíz (mz), trigo (tg) y sorgo (sg). De noviembre 2018 a mayo 2019 se visitó el campo tres veces por mes, el muestreo se realizó por cuadrantes de 2 m 2 .

All plants were identified at the species level and organized by their immigration status. Diversity index, accumulation curves were calculated, also a Kruskal Wallis test and Discriminant analysis were made to compare between weeds populations. 28 species were found, the total richness was obtained for mz and tg but it did not for sg. The corn was the cropping with more species (S= 26) and, a significantly high diversity (H= 2.94), it also was observed in native and exotic weed (H = 1.91 y H = 1.94, respectively). The weed abundance was significantly high in mz. The composition of weed populations was different between crops, the AD with 83% of variance explained separated three groups according to the type of crop, which was reflected in the structure of the weed populations. Plant communities are different between crops despite being in a spatially homogeneous environment. Hence, factors associated with the crops are influencing the diversity patterns observed. Species richness is inside of range of other agroecosystems but, diversity is higher than some studies reported for traditional and intensive farming systems. The present of native species in local diversity is a positive ecological indicator for crops.","PeriodicalId":30046,"journal":{"name":"Polibotanica","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-01-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43139784","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

An ethnobotanical study was carried out in San Pablo Cuatro Venados, Oaxaca, with the purpose of documenting the traditional knowledge of the use, handling and conservation of wild flora, for which a description of the plants that were identified as useful was made. The data was collected through semi-structured interviews and participant observation to collect information on the species; later, collection tours were carried out for subsequent identification. A list of 93 species with direct use was obtained, which were classified into four categories: medicinal (56%), edible (18%), ornamental (13%) and use in tools (9%). According to the botanical record of each species, these were grouped into 43 families, the most frequent being Asteraceae with 40% of the species, followed by the Fabaceae family with 16% and Labiatae with 12%. Likewise, the importance of the selected species in each of the categories was determined by means of quantitative indicators and those with the highest frequency of direct use by the informants were identified.
