CICA (“quinoa”) in the Argentinean Northwest. Quinoa crop to obtain grain for human consumption has begun to spread in the region of Calchaquies Valleys (Tucuman, Argentina) over 2,000 m asl. Because quinoa is a new alternative crop, must be carried out ecophysiological and agronomic studies to get its adequate management. In this study the effect of sowing density on the photosynthetic response against different photon flux densities (DFFF) was analyzed in order to calculate the maximum assimilation (A max ), light saturation point (PSL), light compensation point (PCL), photosynthetic efficiency (O CO2 ) and dark respiration (R n ) values. Data in relation to net photosynthetis assimilacion (A n ), stomatal conductance (g s ), leaf transpiration (T r ), internal CO 2 concentration (C i ), carboxilation capacity (A n /C i ) and intrinsec water use efficiency (EUA i ) are provided. In addition, photosynthetic pigment (chlorophylls and carotenoids) and protective one (absorbance at 305 nm) were measured. This study demonstrates that gas exchange parameters are directly correlated with morphology, foliar anatomy and grains yield and that the sowing density has a direct effect on them.","PeriodicalId":49101,"journal":{"name":"Boletin De La Sociedad Argentina De Botanica","volume":null,"pages":null},"PeriodicalIF":0.6,"publicationDate":"2018-04-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85533840","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}

Biological invasions advance on ecosystems causing major changes in their structure and ecological processes. Ulmus pumila L., is an exotic species that develops processes of invasion in Argentina and mechanical and chemical techniques have been used for its control in the affected sites. Biological control is now considerated as a new alternative. In the present work, the infection capacity of Pleurotus ostreatus on U. pumila plants was evaluated in order to collect and provide basic information to generate new options for biological control of U. pumila. Laboratory tests were carried out to determine the success of establishment of Pleurotus on cuttings of native tree species from the biogeographic district of Espinal and U. pumila. It was found that P. ostreatus had the ability to externally colonize all evaluated species although only in stakes of U. pumila could complete the life cycle. Finally, the anatomical study of the wood indicated that U. pumila is the species, among the studied ones, with greater proliferation of mycelium and even with formation of chlamydospores. In this way, it can be said that this exotic species is more susceptible to fungal infection than the native species studied.","PeriodicalId":49101,"journal":{"name":"Boletin De La Sociedad Argentina De Botanica","volume":null,"pages":null},"PeriodicalIF":0.6,"publicationDate":"2018-04-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79697134","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}

Citrus are fruit trees early introduced into America. Nowadays in Misiones there are 30 ethnovarieties (9 ethnospecies) locally recognized and cultivated in different ways. The objectives of this contribution are to describe the microenvironments where they grow, the practices on those microenvironments and the ethnovarieties present in each one of them, and then to analyze, from a relational approach, the effect of management practices on the processes of domestication of plants and landscape. Fieldwork was performed in Teyu Cuare (San Ignacio) and Cerro Martires (Concepcion), province of Misiones (Argentina), during the years 2010 to 2013. Open-ended and semi-structured interviews were carried out as well as walks with the informants. Seven microenvironments were determined in relation to the presence of citrus, management practices on the plants themselves as well as on microenvironments or groups of microenvironments and by aspects related to vegetation, soil, water availability and proximity to the home. The diversity of citrus recorded in the different microenvironments represents a continuum of varieties representative of the process of domestication in different senses, coinciding in turn with the diversification management practices. The study of management practices allows us to observe current management patterns as well as interpreting nowadays landscapes by inferring past practices.","PeriodicalId":49101,"journal":{"name":"Boletin De La Sociedad Argentina De Botanica","volume":null,"pages":null},"PeriodicalIF":0.6,"publicationDate":"2018-04-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77421918","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}

In the riparian forest of Punta Lara (Buenos Aires province, Argentina) seven woody bird-dispersed species coexist, five of which are native (Ocotea acutifolia, Allophylus edulis, Myrsine laetevirens, Blepharocalyx salicifolius and Citharexylum montevidense), and two are invasive aliens (Rubus ulmifolius and Ligustrum lucidum). While seed dispersal of these species has been studied, other aspects of their reproduction are unknown. In this paper we studied the breeding systems, the quality of the pollination service they receive and their floral visitors. All species are xenogamous. One species (M. laetevirens) is anemophilous and the others are visited mostly by Diptera, Hymenoptera and Lepidoptera. For most of the native species the pollination service seems insufficient. In A. edulis and B. salicifolius natural fruit set was lower than that of hand cross-pollinated flowers, only O. acutifolia and the two exotic showed stigmatic pollen loads sufficient to achieve maximum seed production. A possible explanation for the patterns found lies in the reduction of populations of native species due to the expansion of the aliens, particularly L. lucidum.","PeriodicalId":49101,"journal":{"name":"Boletin De La Sociedad Argentina De Botanica","volume":null,"pages":null},"PeriodicalIF":0.6,"publicationDate":"2017-12-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78102742","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 ANOVA detected highly significant differences among landraces for almost every variable. The first two canonical variates (cv) explain 75% of the overall variation. The discriminant traits associated to the first and second cv are related to ear and kernel dimensions (row number of kernel per ear and kernel width) and mainly to vegetative cycle length. These results along with the cluster analysis allowed the identification of racial groups, which are described. It also confirmed the existence of high variability in these races and from the minimum distance between OTUs a hypothetical evolutionary tree of these set of races was built.
