Studies on water resources are important to understand seed germination. The objective of this study was to evaluate the physiological (germination) response of chia seeds and linseed to water stress. The seeds were placed on paper soaked in solutions of polyethylene glycol in diff erent osmotic potentials. Percentage of germination, fi rst germination count, and germination speed index were evaluated. The reduction of the osmotic potential of the substrate promoted a signifi cant decrease in the germination and vigor of the chia seeds and linseed. In conclusion, seeds of these species are not able to tolerate osmotic potentials equal to or lower than -0.15MPa, being making possible its cultivation areas with concentrations above osmotic potentials.
水资源的研究对了解种子萌发具有重要意义。本研究的目的是评价奇亚籽和亚麻籽对水分胁迫的生理(萌发)反应。将种子放在浸在不同渗透电位的聚乙二醇溶液中的纸上。测定发芽率、首次萌发数和萌发速度指数。基质渗透势的降低使奇亚籽和亚麻籽的发芽率和活力显著降低。综上所述,这些品种的种子不能耐受等于或低于-0.15MPa的渗透势,从而使其种植区域的浓度高于渗透势。

Arbuscular mycorrhizal fungi (AMF) support plant development, however, symbiosis depends on species of both symbionts. This study aimed to evaluate the interaction between rootstock citrus inoculated with species of arbuscular mycorrhizal fungi. Three rootstocks citrange ‘Fepagro C37 Reck’ [ Poncirus trifoliata (L.) Raf. x Citrus sinensis (L.) Osbeck.], ‘Hong-Kong’ kumquat ( Fortunella hindsii Swingle) and ‘Trifoliata’ ( Poncirus trifoliate ) were tested, inoculated with two species of AMF ( Glomus etunicatum W.N. Becker & Gerd.and Acaulospora sp. ) and a treatment not inoculated. We evaluated the height (cm), stem diameter (mm), leaf area (cm² / plant), leaf number, fresh and dry root and shoot weight (g), the level of reserves in tissues and the colonization of AMF in the roots. The species G. etunicatum and Acaulospora sp . colonized the roots of rootstocks, but they were only eff ective for ‘Fepagro C37 Reck’. Poncirus trifoliata had the highest vigor in the absence of AMF.

This study aimed to quantify and elucidate the spatial variability of plant height and abundance of tillers and reproductive structures of the salt marsh grasses Spartina alterniflora Loisel. and Spartina densiflora Brongn. within and between pioneer ( 50 years of colonization) in southern Brazil. Both pioneer populations had taller tillers (p<0.01) than mature populations. Pioneer populations of S. densiflora also showed massive investment on tiller density (10,084 m-2), more infl orescences (557 m-2) and higher fecundity (16,258 seeds m-2) than the mature population (131 infl orescence m-2; 2,199 seeds m-2). High redox and reduction of phosphorus availability in the sediment away from the water line seem to explain decreasing densities of tiller and infl orescences inside S. densiflora mature populations. Fourteen percent of pioneer S. alterniflora tillers flowered and, on average, produced only 0.4 seeds per infl orescence and 76 seeds m-2, whereas mature population did not fl ower.
本研究旨在量化和阐明互花米草(Spartina alternniflora Loisel)株高、分蘖丰度和生殖结构的空间变异。和米草属。在巴西南部的拓荒者(50年的殖民)内部和之间。两个先驱者群体分蘖均高于成熟群体(p<0.01)。在分蘖密度(10,084 m-2)、花序数(557 m-2)和繁育力(16,258粒m-2)方面,先民群体也表现出比成熟群体(131粒花序m-2)更大的投入;2199粒(m-2)。远离水线的沉积物中高氧化还原和磷有效性的降低似乎解释了密草成熟种群中分蘖和花序密度的下降。14%的互花蓟马先驱者开花,平均每个花期只产生0.4粒种子,m-2只产生76粒种子,而成熟群体不开花。

In this paper, we studied the pollen morphology of 11 species of epiphytic Cactaceae family in Rio Grande do Sul, southern Brazil. We provide descriptions, measurements, photomicrographs, as well as information on ecology and biogeography. The pollen grains are variable in size (medium, large and giant) with prolate-spheroidal to prolate forms; 3-colpate aperture ( Lepismium cruciforme (Vell.) Miq. and Rhipsalis cereuscula Haw.) and 6-colpate (remaining species); exine with tectum and small granulate texture and perforations; except for Epiphyllum phyllanthus (L.) Haw, colpi are covered by thin granulate membrane; heteromorphism in the apertures of L. houlletianum (Lem.) Barthlott, L. warmingianum (K. Schum.) Barthlott and Rhipsalis campos-portoana Loefgr was observed. Results indicate two morphological patterns in the study taxa: the fi rst (I) is related to pollen grains with 3-colpate aperture and second (II) with 6-colpate aperture

The objective of this work was to analyze the effect of cotyledon loss at diff erent times of initial bean growth. The experimental design was completely randomized in a factorial scheme of 2x5, seedlings with zero and one cotyledon, interacting with fi ve extraction stages: zero, one, two, four, and six days after germination, with fi ve replicates composed of three seedlings. After 15 days, the following parameters were evaluated: mean root and shoot length; mean stem diameter; leaf area; total shoot and root dry mass; phloem and xylem diameter; and thickness of abaxial and adaxial epidermis. Removing cotyledons during the initial development of the bean plant infl uenced all the parameters evaluated in this work, except the mean diameter of the stem with one cotyledon. The removal of cotyledons in the fi rst days of extractions hinders the initial development of the plant, as well as making it more susceptible to the environment.
本研究的目的是分析大豆生长初期不同时期子叶损失的影响。试验设计采用2 × 5个零子叶和1子叶幼苗的全随机因子设计,分别与萌发后0、1、2、4、6 d 5个提取阶段相互作用,5个重复,每重复3个幼苗。15 d后,评估以下参数:平均根长和茎长;平均杆径;叶面积;茎和根总干质量;韧皮部和木质部直径;以及正面和背面表皮的厚度。在大豆植株发育初期去除子叶会影响本研究中评估的所有参数,除了具有一个子叶的茎的平均直径。在提取的第一天去除子叶会阻碍植物的初始发育,并使其更容易受到环境的影响。

Nevertheless, the results of this study provide consistent indications of the allelopathic potential of tested species.","PeriodicalId":54998,"journal":{"name":"Iheringia Serie Botanica","volume":null,"pages":null},"PeriodicalIF":0.4,"publicationDate":"2017-09-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75589709","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 edge effect is defined as the change of biotic and abiotic characteristics in the first meters of a forest fragment from the edge towards its interior. In fragments formed by human activities, this change generates increased richness and abundance, as well as changes in the structure of the forest species of soil seed bank in the border region. This study demonstrates that in natural fragments of cloud forests, the abundance and richness positively influence the linear relation from the edge to interior, mainly by distances of 120 and 180 meters from the edge. This effect can be a result of new plant growth, or ‘pioneer’ occupation in gaps in the forests generated by large fallen trees.
边缘效应被定义为森林碎片从边缘到内部的前几米生物和非生物特征的变化。在人类活动形成的片段中,这一变化增加了丰富度和丰度,同时也改变了边境地区土壤种子库的森林物种结构。本研究表明,在云雾林的自然片段中,丰度和丰富度对边缘到内部的线性关系有正向影响,主要受距离边缘120米和180米的影响。这种影响可能是新植物生长的结果,或者是“先驱者”占领了大片倒下的树木形成的森林空隙。

A Estacao Ecologica da Universidade Federal de Minas Gerais e uma importante unidade deconservacao urbana com vegetacao de Mata Semidecidua e Cerrado, sendo area de inumerosestudos com a fauna e flora locais. No entanto, informacoes sobre briofi tas sao completamente ausentes, o que difi culta estudos mais aprofundados sobre estas plantas. O objetivo desse estudo foi registrar as especies de briofitas presentes na Estacao Ecologica da referida Universidade, apresentar informacoes sobre sua reproducao e dados complementares sobre o micro habitat e distribuicao geografica das especies. A partir de 60 amostras de briofitas coletadas em diferentes substratos foram encontradas nove especies de hepaticas e 15 de musgos. O musgo Isopterygium byssobolax (Mull. Hal) Paris e novo registro para o estado, propagulos assexuados sao descritos pela primeira vez em Donnellia lagenifera (Mitt.) W.R. Buck e a hepatica Cylindrocolea planifolia (Steph.) R.M.
