Seed vigor, antioxidant metabolism and initial growth characteristics of red rice seedlings under different light intensities Acta Botanica
Aumonde,Tiago Zanatta; Pedó,Tiago; Borella,Junior; Amarante,Luciano do; Villela,Francisco Amaral.
This work aimed to evaluate the effect that different intensities of light have on the physiological attributes of red rice seeds and seedlings. Before and after emergence, seedlings were exposed to light levels of 35%; 65% and 100% in a greenhouse. We evaluated shoots and roots, in terms of length and dry mass, as well as leaf area and content of chlorophyll (a,b and total). In leaves and roots, we quantified the activity of superoxide dismutase (SOD), ascorbate peroxidase (APX), catalase (CAT) and guaiacol peroxidase (POX). We determined the leaf area ratio (F A), leaf mass ratio (F W), specific leaf area (S A), and shoot/root ratio (P W). At higher light intensities, shoot length decreased, whereas root length, dry mass and number of tillers increased....

Growth and physiology of jelly palm (Butia capitata) grown under colored shade nets Agronomy
Costa, Irton de Jesus Silva; Costa, Bárbara Nogueira Souza; Assis, Franscinely Aparecida de; Martins, Adalvan Daniel; Pio, Leila Aparecida Salles; Pasqual, Moacir.
 Butia capitata (Mart.) Becc., commonly known as jelly palm, is a palm tree native to the Cerrado biome. It is considered an endangered species owing to intensive extractive exploitation of its fruits, with slow and uneven seminiferous propagation as an aggravating factor. Thereby, there are some bottlenecks related to jelly palm seedling production that needs to be optimized. Light quality and intensity is very important to seedling production, as it controls the metabolism of plants and consequently their growth and development. Thus, the aim of this work is to evaluate the effect of shade nets on the growth and physiological aspects of jelly palm seedlings. The experimental design was completely randomized, with five treatments, ten replicates and eight...

SCALON,SILVANA P.Q.; MOTA,LEANDRO H.S.; MUSSURY,ROSILDA M..
The present work aimed to evaluate the osmotic conditioning and shading on the germination and on the initial growth of aroeira seedlings. The seeds were pre-imbibed in solutions with different concentrations of PEG (polyethylene glycol) and KNO3 and incubated at 10°C and 20°C temperatures, during 0 (control), 12 and 24 hours. After these periods, the seeds were dried until they reached the initial levels of humidity. After that, they were put for germinating in BOD (Biochemical Oxygen Demand) chambers, at alternated 20-30°C. The control treatment and the pre-conditionings that presented the best results in BOD germination were selected, PEG (-1.0 MPa) + KNO3 (-1.0 MPa) and KNO3 (-1.0 MPa), with pre-imbibition for 12 h and incubated in BOD at 20°C.

Silvopastoral system with Eucalyptus as a strategy for mitigating the effects of climate change on Brazilian pasturelands Anais da ABC (AABC)
BOSI,CRISTIAM; PEZZOPANE,JOSÉ RICARDO M.; SENTELHAS,PAULO CESAR.
Abstract The aim of the present study was to assess the effect of Eucalyptus trees in a silvopastoral system on the microclimate and the capacity of that to mitigate the effects of climate change on pasturelands. This study included an open pasture of Piatã palisadegrass and an adjacent pasture that contained both palisadegrass and East-to-West rows of Eucalyptus trees, with 15 m between rows, 2 m between trees within rows. The micrometeorological measurements were collected at several distances from the tree rows and in the open pasture. The silvopastoral system was associated with greater between-row shading when solar declination was high and greater near-tree shading when solar declination was around -22°. Both soil heat flux and temperature were...

Modifications on leaf anatomy of Coffea arabica caused by shade of pigeonpea (Cajanus cajan) BABT
Morais,Heverly; Medri,Moacyr Eurípedes; Marur,Celso Jamil; Caramori,Paulo Henrique; Ribeiro,Ana Maria de Arruda; Gomes,José Carlos.
Modifications on leaf anatomy in Coffea arabica shaded with pigeonpea (Cajanus cajan), compared to cultivation under full sun, were assessed. The leaves fully exposed to sunlight presented thicker cuticles and cellular walls, narrower epidermis cells, palisade parenchyma with longer cells, thicker lacunar parenchyma, fewer intercellular spaces and a larger stomata number. Leaves under dense shade presented a narrower cuticle and cellular wall; a mesophyll with smaller volume, but with larger intercellular spaces; and epidermis with thicker cells and a smaller stomata amount, surrounded by subsidiary cells of smaller dimensions. Plants grown under full sunlight presented higher values of net photosynthesis. The results evidenced that the species C. arabica...

Partitioning of nitrate reductase activity in Coffea arabica L. and its relation to carbon assimilation under different irradiance regimes Braz. J. Plant Physiol.
Carelli,Maria Luiza C.; Fahl,Joel I..
The distribution of in vivo nitrate reductase (EC 1.6.6.1) activity (NRA) between leaves and roots was studied in young coffee plants (Coffea arabica L.) grown in pots with watered sand in a glasshouse and irrigated with nutrient solution. The influence of irradiance regimes on the partitioning of NRA, and its relation with CO2 assimilation, was also evaluated in plants grown under approximately 20, 50 and 100% of full sunlight. Time-course of nitrate accumulation in nitrogen-starved plants showed a similar pattern in leaves and roots after supplying 15 mmol L-1 nitrate, indicating efficient ability of the roots to export nitrate to the shoot. At the same time, NRA was rapidly induced in both tissues. In shoots, NRA partitioning was synchronized among the...

Raai,Murthazar Naim; Zain,Nurul Amalina Mohd; Osman,Normaniza; Rejab,Nur Ardiyana; Sahruzaini,Nurul Amylia; Cheng,Acga.
ABSTRACT: An experiment was conducted to investigate the effects of different shading regimes [i.e., 60% (heavy), 30% (moderate), and 0% (control)] on 25 traits associated with the morphological features, photosynthetic gas exchange and agronomic characteristics of winged bean (Psophocarpus tetragonolobus), an underutilized protein-rich legume from the tropics. Collectively, 80% of the studied variables displayed significant differences (P<0.05) between at least two shade treatments. Shading generally showed most pronounced effect on the physiological traits of the legume, whereby the stomatal conductance, photosynthetic and transpiration rate differed significantly among plants for all treatments. The non-shaded plants were observed to have superior...

Lopes,Clenardo Macedo; Paciullo,Domingos Sávio Campos; Araújo,Saulo Alberto do Carmo; Morenz,Mirton José Frota; Gomide,Carlos Augusto de Miranda; Maurício,Rogério Martins; Braz,Thiago Gomes dos Santos.
ABSTRACT: The silvopastoral system has been suggested as an alternative to recover degraded pastures in tropical regions. However, trees reduce the light available for pastures, which may affect the growth and herbage accumulation. The objective of this study was to evaluate the morphogenesis, canopy structure and herbage accumulation of signalgrass ( Brachiaria decumbens ) subjected to three light regimes (0, 20 and 70% of natural shading) and two fertilization levels (presence or absence of nitrogen, phosphorus and potassium). Leaf and stem elongation rates increased under shading but did not vary with fertilization. The leaf appearance rate was greater under fertilizer treatment but was generally similar among light regimes. The tiller density was...

Relaciones entre radiación solar, desarrollo y calidad de cactáceas ornamentales Colegio de Postgraduados
Sánchez Pérez, Anna Magali.
Las cactáceas tienen flores y características morfológicas atractivas que las hacen plantas ornamentales muy apreciadas; se utilizan principalmente como ornato en exteriores pero algunas también se pueden utilizar como plantas de interior; sin embargo, en interiores hay bajos niveles de radiación fotosintéticamente activa (RFA), lo que influye en su crecimiento, desarrollo y vida útil. En México hay poca investigación sobre el tema, por lo que el objetivo de esta investigación fue analizar el efecto de diferentes niveles de RFA en el crecimiento, periodo de floración y contenido de pigmentos (clorofila “a”, “b”, carotenoides y betalaínas) en cuatro especies y analizar su capacidad de adaptación a bajos niveles de RFA.

Effects of light intensity modification by reflective aluminized screenhouse on sweet pepper growth and yield REA
Ferreira,Regis de C.; Bezerra,Ricardo de S.; Rosa,Juliano Q. S..
Sweet pepper is one of the ten most consumed vegetables in world. Although it develops better under protected environment, the cultivation in tropical countries is practiced in open field due greenhouse structure higher costs. Unfortunately, such practice has compromised the crop to reach either best yield or fruit quality. Since production and cost are the most important criteria for agricultural production, we aimed to evaluate reflective aluminized polypropylene shading net influence on sweet pepper (Capsicum annuum L.) growth and production as intermediary alternative for low/middle income producers from Brazilian tropical regions. Sweet pepper Magali R hybrid was cultivated in two environments: FC - field conditions (control) and RS - reflective...
