Sugarcane (Saccharum spp.) is one of the most important crops in world. Drought stress a major abiotic factor that significantly reduces sugarcane yields. However gene network mediates plant responses to water remains largely unknown several crop species. Although microRNAs mediate post-transcriptional regulation during have been described other species, role drought has not studied. The objective this work was identify miRNAs are differentially expressed under and correlate expression with...
The expansion of sugarcane (Saccharum spp.) in Brazil has been boosted by the growing demand for bio-fuels all over world and requires occupation new agricultural areas, including regions with unfavorable agro-climatic conditions. This observational study makes an analysis relationship between stomatal conductance, gas exchange photosynthesis fields subject to different ambient conditions growth phases. It was noted that conductance had a much higher control on than transpiration. Even under...
Sugarcane (Saccharum spp.) is the most promising crop for renewable energy. Among diverse stresses that affect plant productivity, drought stress frequently causes losses in sugarcane fields. Although several studies have addressed responses to using controlled environments, under field conditions are largely unknown. Recently, microRNA (miRNA)-mediated post-transcriptional regulation has been described as an important and decisive component vegetal development resistance modulation. The...
In this study, we aimed to provide information about the use of silicates in plant cultivation.Although silicon (Si) is one most abundant elements found soils substantial quantities, various classes soils, mainly sandy ones, present low amounts available Si their upper horizons.In these some plants such as sugarcane and rice, which have keen ability accumulate tissues, can respond favorably fertilization.Silicates behave similarly calcium magnesium carbonates soil, promoting chemical...
The ability to expand crop plantations without irrigation is a major goal increase agriculture sustainability. To achieve this end, we need understand the mechanisms that govern plant growth responses under drought conditions. In study, combined physiological, transcriptomic, and genomic data provide comprehensive picture of recovery in leaves roots sugarcane. Transcriptomic profiling using oligoarrays RNA-seq identified 2898 (out 21,902) 46,062 373,869) transcripts as differentially...
O estresse hídrico afeta grande parte da agricultura mundial, razão por que se propôs, através deste trabalho, avaliar o comportamento, em casa-de-vegetação, de quatro variedades cana-de-açúcar (SP79-1011, RB72454, RB98710 e RB92579) submetidas a déficit durante fase inicial crescimento vegetativo. As plantas foram cultivadas vasos plásticos contendo 15 kg solo. estudo foi um fatorial (4 x 3 níveis água disponível no solo), delineamento inteiramente casualizado, com cinco repetições. Os solo...
Maturation is a characteristic of sugarcane plant (Saccharum spp.) and even when grown under the same soil climate conditions varieties differ on maturation curve. Thus, studies that allow establishing curves different genotypes in local may indicate proper harvesting period to ensure better quality raw material. This study aimed analyze levels soluble sugars during phase assess technological productivity indexes four irrigated region Rio Largo, Alagoas. The experiment was conducted...
The purpose of the present study was to analyze gas exchanges in leaves and parameters productivity beans (Phaseolus vulgaris, L.) submitted two water deficiency periods during which three regimes were employed: W1 (1,0 ETo entire plant cycle); W2 up flowering period irrigation interruption from 37 51st day following sowing, W3 (in addition reproductive phase, deficit also applied vegetative stage). Photosynthesis one main physiological factors affected by deficit. This not only caused...
Castor bean is one of the crops with potential to provide raw material for production oils biodiesel. This species possess adaptive mechanisms maintaining water status when subjected drought stress. A better understanding these under field conditions can unravel survival strategies used by this species. study aimed compare physiological adaptations Ricinus communis (L.) in two regions different climates, semi-arid and semi-humid subject The plants showed greater vapor pressure deficit during...
The present study investigated the influence of two Brazilian environments on physico-chemical and physiological properties Jatropha curcas L. (physic nut) – an oilseed plant great potential in biodiesel production. Fruits seeds plants grown Atlantic rainforest (AF) semiarid climate Caatinga (SA) were compared. from SA longer, wider heavier than those AF. In contrast, AF larger seeds. Soluble sugars, protein, relative water content electrical conductivity significantly exceeded that by 28%,...
Abstract Drought is one of the main factors affecting productivity agricultural crops, and plants respond to such stress by activating various physiological biochemical mechanisms against dehydration. The present study investigated two varieties sugarcane ( Saccharum spp.) with contrasting responses drought (RB867515, more tolerant; RB855536, less tolerant) subjected them progressive conditions (2, 4, 6 8 days) followed rehydration. caused a decrease in water potential (ψ w ) osmotic os...
Abstract Drought is one of the major climatic factors that reduce crop yields in cultivated areas around world, and studies on physiological responses may help selection drought tolerant genotypes. Thus, this work aimed to correlate gas exchange, photosynthetic efficiency, carbon isotope discrimination (Δ 13 C) antioxidant activity sugarcane varieties submitted water stress under field conditions. Six were three development stages: tillering, intense growth ripening. In all varieties,...
ABSTRACT Sugarcane plays an important role in the Brazilian agribusiness. However, poor rainfall distribution and soil acidity directly affect its production Northeast Brazil. Gypsum improves physical chemical properties, attenuating effects of water stress edaphic environment. This study aimed at determining effect gypsum doses on sugarcane growth yield. A field experiment was conducted using a 3 x 5 factorial arrangement organized randomized block design, with four replications. Treatments...
