Como inóculo se utilizaron semillas de porotos y garbanzos, granos de avena y cebada, utilizando los granos de avena como control positivo de crecimiento del micelio. Se prepararon los sustratos de cultivo en bolsas de poli- propileno con 1/2Kg y 1 kg de sustrato húmedo de virutas de madera, bagazo de caña procesado, hojarascas y granos de avena en baja proporción para enriquecer el sustrato, utilizando las virutas de Cedrela fissilis como control positivo; las bolsas se esterilizaron por dos h a 120°c, 1 atm de presión y luego se inocularon y fueron incubadas en la oscuridad a 18/25°c de temperatura y aproximadamente 70% de hu- medad ambiente, durante 22-35 días. Una vez cubierto de micelio el sustrato, se pasó a la inducción con 12 h de luz y oscuridad, riego de dos veces por día, temperatura y humedad constantes. Al cabo de 30 a 35 días ya se obtuvieron basidiomas. Se evaluó la eficiencia biológica (EB%) desde el momento de la inducción hasta la cosecha. El sustrato con mejores resultados después del control (53,20%EB) fue la mezcla de virutas con avena y hojarascas con una EB (45,20%). Se obtuvieron fructificaciones en todos los sustratos con excepción de bagazo de caña. La utilización de desechos orgánicos para el cultivo de hongos puede resultar una interesante alternativa de reciclaje de materia orgánica para generar cultivos a pequeña o gran escala.","PeriodicalId":33272,"journal":{"name":"Lilloa","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-06-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45934118","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}

Scarcity and variability of the water resource determine the spatial distribution of vascular plants. Areas devoid of vegetation are commonly colonized by microbial communities (mosses, cyanobacteria, lichens) called biological soil crusts (BSCs), which modify numerous biogeochemical properties of the substrate. Cyanobacteria are fundamental constituents of BSCs, they synthesize chlorophyll a, phycobilins and fix atmospheric nitrogen (N), representing one of the main sources of N for some arid ecosystems. The objective of this work is to contribute to the knowledge of the cyanobacteria present in BSCs of the Monte Central desert, in different landscape units of eastern Mendoza (natural reserves and grazing lands). Biotic and abiotic material was collected during the years 2015 and 2016 in each environmental unit. For the identification of cyanobacteria, morphological characteristics observed under light microscope, along with taxonomic keys were used. Thus, 12 new records of cyanobacteria are repor ted in BSCs, improving our knowledge of these biocrusts, their geographical distribution and ecology in the province of Mendoza, Argentina.","PeriodicalId":33272,"journal":{"name":"Lilloa","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-12-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43000372","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}

To obtain the seedlings, 60 seeds of each species were sown in terrines with a coarse sand substrate. After 20 days from sowing, 15 seedlings were selected and the lengths of hypocotyl, epycotyl were measured as well as, the length and width of leaflets, which showed significant differences except in the lengths of the leaflets. Optical microscope slides were done for the epidermis and cross-sections of primary root, hypocotyl, epycotyl, petiole and leaflet, the sections were analyzed, illustrated and photographed. Both species share the same structure of diarch root, glabrous adaxial face and anfistomatics characteristics with anomocytic stomata in leaflets epidermal layers. The most noticeable differences between the species seedlings are the presence of a laminar collenchyma layer and the larger number of vascular bundles in the hypocotyl and epycotyl of L. angustifolius and a starchy layer sheath in the hypocotyl of L. albus . The cordate form and the two lobes emerging from a center channel in the petiole of L. angustifolius, reaffirm other morphological similarities with the species L. gibertianus . The major differences in the leaflets are the width and the structure of the mesophyll which is dorsiventral in L. albus and is isobilateral in L. angustifolius . The structure of an epitricopodium in tricelular trichomes are described for the first time for the genus Lupinus . The anatomical structures were com- pared and discussed with those of other species of the genus, with environmental conditions and with modifications by plant breeding. This work serves as a basic knowledge for further research to find if there are relationship between support tissues and transport system with the plant protection strategies against pathogen infections and water stress.","PeriodicalId":33272,"journal":{"name":"Lilloa","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-06-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45289506","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}

It is used in popular medicine as antilithic, diuretic and vulnerary; it also has pharmacological activity as a gastroprotective, antibacterial, anti-inflammatory and anti - oxidant. The objective of this study is to characterize the anatomy of the basal or proximal, middle and distal zones of the stem and the rhizome of Solidago chilensis var. chilensis in vegetative state to study future relations between parts of the plant and the production of phytochemicals, and to contribute to its characterization as a crude drug. The stem, rhizome and adventitious roots of vegetative individuals collected in the province of Buenos Aires were divided into three zones (distal, middle and basal or proximal) and studied by conventional histological techniques for optical and scanning electron microscopy. The results show that non-glandular whip and conical trichomes are located mainly in the leaves. The density of whip trichomes is higher in the leaves of the distal and middle stem. Biseriate glandular trichomes are only present in the distal leaves and stem and in the scales of the rhizome. The stomata are located in both foliar epidermis, but its density is lower in the basal leaves. There are schizogenous secretory spaces in all analyzed organs. In the leaves are associated with xylem and phloem, and in the scales, only with phloem. In the stem, rhizome and roots, they are located in the cortex associated with phloem; they are very well developed in the distal leaves and stem. Stems, rhizomes and roots have aerenchyma in the cortex, which develops larger intercellular spaces towards their basal or proximal zones. Calcium oxalate crystals in the form of needles, styloids and prisms are abundant in the aerenchyma and pith of the stem upper distal zone.","PeriodicalId":33272,"journal":{"name":"Lilloa","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-06-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41904731","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}
