BACKGROUND: The year-round availability of apples (Malus × domestica Borkh.) depends on post-harvest technologies, which are essential for the retention of fruit sensory and chemical properties by delaying senescence. The effectiveness of strategies for preserving the quality of apples depends on complex interactions between the storage environment and endogenous biological factors. In the current work, we integrated instrumental, sensory, and transcriptional data to determine the role of conservation technologies cold storage, controlled atmosphere, and 1-methylcyclopropene-mediated ethylene blockage on the long-term conservation of apples. RESULTS: The results demonstrated that inhibition of the consumer's perception of the apples? ethylene content is essential for long-term cold storage, and such quality conservation can be achieved by reducing oxygen pressure. Overall appreciation of apples after storage was determined mainly by their texture, with crispness and juiciness contributing favorably, and mealiness contributing negatively. Reduced oxygen pressure and inhibition of ethylene perception exerted distinct effects on the transcription of candidate genes associated with ripening in apple. Hexose and cell-wall carbohydrate metabolism genes exhibit distinct expression patterns under storage. CONCLUSION: Inhibition of ethylene perception and reduction of relative oxygen pressure under cold storage both promote similar conservation of apple sensory traits under long-term cold storage. Texture was the main contributor to global appreciation of apples subjected to long-term storage. The conditions that were investigated were able to delay, but not fully prevent, senescence, as evidenced by physicochemical and gene expression analyses. The expression of gene-encoding enzymes involved in hexose metabolism was mainly developmentally regulated, whereas storage conditions exerted a stronger effect on the expression of genes associated with cell-wall metabolism.

The importance of sugarcane (Saccharum officinarum) for the economy of Brazil and as an energy alternative to oil derivatives is indisputable nowadays. According to IBGE, in 2013, with a production of about 28.2 million tonnes and productivity of 63.3 tons per hectare the state of Alagoas has come to occupy a prominent position in the Northeast of Brazil. In this sense the present study aims to analyze the economic importance of sugarcane in the formation of the Gross Value of Agricultural Production (GVAP) in nine municipalities in the region of the Coastal Tablelands of Alagoas State. Shift-Share Method was used for segmentation of the effects of the harvested area, the productivity and the price paid to producers in the state of Alagoas, in four periods of six years (1990 a1996, 1996-2002, 2002-2008 and 2008 to 2013) and also in the entire period (1990-2013). In the comparison between the group of municipalities in the Coastal Plains of Alagoas and the group of the largest producers in the state, the analysis of the targeted effect of the variables on the Percentage Change In (PCI) of GVAP of sugarcane indicated negative effect of the harvested area (-0.7 % and -0.6%) and positive effects of productivity (0.9% and 0.9%) and price (2.3% and 2.4%). Therefore it is concluded that the contribution of the price was decisive for increasing the PCI of sugarcane GVPA, within the two groups of municipalities studied, between 1990 and 2013. |
