MITES IN THE PARENCHYMA OF JUNCUS PROCERUS IN MARSHEY WETLANDS IN THE BIO BIO REGION, CHILE
Provedor de dados: 72
Autores: Villagrán-Mella,Romina; Casanueva,María E.; Parra,Luis E.
The first record of mites in the parenchyma of Juncus procerus in marshey wetlands in the region of Bio Bio, Chile, is presented. Nine genera and families and three suborders were found. Eight species are new records for Chile and have not been previously cited as mites associated with aquatic environments. They are the following: Mesostigmata: Holoparasitus sp. and Hypoaspis sp., Prostigmata: Trombidium sp., Trombiculidae sp., Balastium sp., Cyta sp. and Eupodes sp.; and Oribatida: Pergalumna sp. Facts about habitats and known distribution are included for all found taxa

Wood anatomy of the Euphorbiaceae, in particular of the subfamily Phyllanthoideae
Provedor de dados: 16
Autores: Mennega, Alberta M.W.
The great variety in wood structure of the large family Euphorbiaceae makes it impossible to describe briefly a general wood pattern. Nevertheless, a more or less clear division into four anatomical groups can be made. A short overview is given of the wood structure of the uni-ovulate subfamilies Acalyphoideae, Crotonoideae, and Euphorbioideae, following the classification by Webster. These subfamilies cannot be distinguished by their anatomy. The paper is mainly devoted to the bi-ovulate subfamily Phyllanthoideae. Within this subfamily, two groups can be recognized on the basis of their wood anatomy: the Aporusa type with a great number of primitive characters, and the Glochidion type, in which primitive features such as scalariform vessel perforation...

ABSTRACT: The most widely used herbicide in coffee crop is glyphosate, it inhibits the biosynthesis of secondary metabolites, responsible for structures and substances of plant defense. This work aimed to evaluate the morphoanatomy, total phenols, flavonoids and caffeine in leaves of Arabica coffee submitted to different sub-doses of glyphosate. The treatments were combinations of three coffee cultivars (MGS Travessia, Oeiras MG 6851 and Catuaí IAC 144) and five sub-doses of glyphosate (0.0, 57.6, 115.2, 230.4 and 460.8 g a.e. ha-1). The total thickness of the leaf blade, thickness of adaxial and abaxial epidermis, palisade and spongy parenchyma, in addition to the total phenol, total flavonoids and caffeine were evaluated 30 days after spraying. Catuaí...

Acclimatization and leaf anatomy of micropropagated fig plantlets
Provedor de dados: 94
Autores: Chirinéa,Chrystiane Fráguas; Pasqual,Moacir; Araujo,Aparecida Gomes de; Pereira,Alba Regina; Castro,Evaristo Mauro de.
The survival of micropropagated plants during and after acclimatization is a limiting process to plant establishment. There is little information on how the anatomy of vegetative organs of Ficus carica can be affected by culture conditions and acclimatization. The present research aimed to study the effects of time on culture medium and substrates during the acclimatization of fig tree plantlets produced in vitro, characterizing some leaf anatomy aspects of plantlets cultured in vitro and of fig trees produced in field. Plantlets previously multiplied in vitro were separated and transferred into Wood Plant Medium (WPM) where they were kept for 0, 15, 30, 45 and 60 days. Different substrates were tested and studies on leaf anatomy were performed in order to...

Leaf anatomy changes related to physiological adaptations to flooding in Amazonian tree species
Provedor de dados: 61
Autores: Herrera,Ana; Escala,Marcia; Rengifo,Elizabeth.
In trees of the seasonally flooded forest of the Mapire River in Venezuela, early flooding induces a reversible diminution in leaf conductance and photosynthetic rate. With the aim of finding an anatomical explanation for the observed responses of leaf gas exchange, the characteristics of emerged leaves developed under drainage or after three months of flooding were examined in the tree species Acosmium nitens, Campsiandra laurifolia, Duroia fusifera, Eschweilera tenuifolia, Pouteria orinocoensis and Symmeria paniculata and in leaves developed only under flooding in Inga spuria and Tachigali davidsei. Anatomy was remarkably similar among species and families and consisted of a bi-layered palisade parenchyma, a 5-6-cell-thick spongy parenchyma and large...

Leaf tissues proportion and chemical composition of Axonopus jesuiticus x A. scoparius as a function of pig slurry application
Provedor de dados: 65
Autores: Lajús,Cristiano Reschke; Miranda,Mário; Basso,Simone Meredith Scheffer; Carneiro,Cercí Maria; Escosteguy,Pedro Alexandre Varella.
This study aimed to evaluate the chemical and anatomical attributes of leaves of giant missionary grass to application of 0, 62, 124, 186, 248 and 310m³ ha-1 of pig slurry. At 83 days after the last application of fertilizer, the leaf blades were collected, fixed in FAA 70%, sectioned, stained, photographed and digitalized. The transversal section of leaf blades were evaluated for proportion of epidermis, lignified vascular tissue + sclerenchyma, non-lignified vascular tissue and parenchyma with an image-processing system calibrated to 1mm pixel-1. Leaf samples were analyzed for crude protein, acid detergent fiber, neutral detergent fiber and hemicellulose content by near infrared reflectance spectroscopy. The pig slurry application up to 310m³ ha-1...
