Obtaining polysaccharides from grape cell walls is an interesting topic for the wine industry given its implications with regards to wine treatments and potential sensory attributes. In the present work, several conditions (i.e., a chelating agent, pH, titratable acidity, extraction time, number of successive extractions, solid to liquid ratio and alcoholic fermentation) were tested to assess their effects on the yield of soluble polysaccharides obtained from grape skins. Among the four tested solvents (i.e., water, tartaric acid, ammonium oxalate, and ethylenediaminetetraacetic acid), aqueous ammonium oxalate was the most effective for polysaccharide extraction but also produced the highest amount of protein impurities. Increasing the number of successive extractions or modifying the extraction time does not increase the amount of total extracted polysaccharides but produces more polysaccharides with a low molecular mass. The extraction yield of polysaccharides does not increase by increasing the tartaric acid concentration; however, the extraction yield increases by increasing the pH of the solvent or decreasing the solid to liquid ratio during the extraction. During the fermentative maceration of the skins, the extraction of soluble polysaccharides is significantly higher than that obtained with aqueous solvents. Thus, it seems that grape skins contain some pectic polysaccharides that are tightly bound to the cell wall matrix that are not immediately solubilized by aqueous buffers and are released under alcoholic fermentation conditions.

Peumus boldus is an endemic Chilean tree whose edible fruit lack a history of scientific research. The aim of this study was to determine its nutritional composition (moisture, ash, crude fiber, proteins, carbohydrates and lipids) and polyphenolic content (total phenolic content, HPLC-DAD, HPLC-MS/MS analysis) at different stages of development. The results show that the fruit decreased in ash, crude fiber and total phenolic content throughout its development, while its carbohydrate and protein content increased. An increase in phenolic molecules such as catechin and epicatechin was also observed. This is the first report on the nutritional composition and phenolic content of Peumus boldus Mol. fruits.

Soil erosion by rainfall is a process that demands management, both for the prevention of excessive soil erosion and for the protection of the quality of freshwater bodies. Erosion coefficients (K-factors) of the universal soil loss equation (USLE)/revised USLE (RUSLE) model were assigned to 99 mapped Uruguayan soil types at 1:1,000,000 scale. This work developed a linear mixed model (LMM) with 79 soils with assigned K-factors, in which the following variables were considered: soil taxonomy, chemical composition, and parent material. The developed LMM had an R2=0.86, in which the soil taxonomy (p<0.0001), parent material (p=0.0174), clay (p=0.0005) and sand (p=0.017) contents had significant statistical effects. The prediction capacity of this model was assessed with 10 soils not previously used in development of the LMM with assigned K-factors. The prediction assessment had an R2=0.84 and a mean error of 9.08% of the mean K-factor value. The LMM developed was used for the allocation of K-factors to soils mapped at a 1:20,000-resolution. Thus, the use of LMM increased the soil area with assigned K-factors from 111,822 km2 (at a scale of 1:1,000,000) to 174,132 km2 (1:20,000).

The objective of this study was to estimate genetic parameters for milk production and reproduction traits, with phenotypic and pedigree information from the Dairy Overo Colorado breed from southern Chile. Single and multi-trait mixed models were used to analyze the data. Analyses were performed using ASReml software. Heritability estimates for milk yield, fat yield, protein yield, fat content, protein content, age at first calving and calving interval, were 0.29, 0.34, 0.30, 0.56, 0.56, 0.01 and 0.002, respectively. Genetic correlations between yield traits were high and positive (≥ 0.81). Genetic correlations of milk yield with fat content (-0.32) and protein content (-0.30) were unfavorable. Genetic correlation estimates between age at first calving and yield traits were negative between -0.71 and -0.29. Phenotypic correlations between calving interval and milk yield traits were slightly positive (0.06-0.09), suggesting a weak relationship between reproduction and yield in this population. Genetic variation is considerable for milk production traits. Genetic improvement for age at first calving and calving interval may be slow, because small differences between animals and low reliabilities are expected for estimated breeding values for these traits due to low heritabilities. The design of an efficient breeding program for yield traits based on artificial insemination for this population is feasible using either progeny testing or genomic breeding value prediction for selecting sires.

The aim of this study was to characterize the phenological, vegetative and reproductive behavior variables of ‘Frantoio’ olive trees in an “off” year (with a low crop load) and an “on” year (with a high crop load). To do this, during the 2011–2012 and 2012–2013 seasons, “off” and “on”, respectively, phenological variables, plant growth (shoots and roots) and reproductive growth (type of flower, fruit set and growth), were monitored biweekly. In addition, the yield per tree was assessed, and the crop load was estimated. The main results showed that crop load strongly influenced these variables. The distribution and intensity of vegetative growth, both in the roots and aboveground, decreased more and had lower intensity in the high fruiting season, with a large part of this growth occurring prior to flowering. With respect to reproductive variables, a higher percentage of perfect flowers and fruit set in the low flowering season was observed compared to the high load season. These results suggest a partial crop load compensation mechanism under low flowering conditions. This mechanism, however, does not compensate for lower production in the “off” season. In terms of volume, fruit growth was similar between seasons until pit hardening, then the fruit growth rate dropped dramatically in the “on” season, indicating that fruit growth, until pit hardening, would not be affected by the presence of a higher number of fruits per tree.

An effective way to control post-harvest rotting of table grapes is the use of sulfur dioxide (SO2). However, under certain conditions, the use of SO2 can cause significant loss, mainly associated with bleaching of the berries. Therefore, it is believed that the use of bags with and without copper nanoparticles that modify the atmosphere will allow for the control of Botrytis cinerea as well as the ability to dispense with the use of sulfur dioxide generation. The objective of this test is to evaluate the use of bags with and without copper nanoparticles that modify atmosphere and to evaluate their ability to control post-harvest B. cinerea, as well as their effect on the conservation of physical and chemical characteristics of table grapes. The results indicate that the use of air bags with or without copper nanoparticles that modify the atmosphere and do not require sulfur dioxide generation were able to control B. cinerea post-harvest and preserve the physical and chemical parameters of grape table cv. ‘Thompson seedless’. Significant differences were seen in parameters such as whitening, dehydration and incidence of stalk rot. A group of panelists could not distinguish differences in the sensory attributes and acceptability of the grapes regardless of treatment.

Avocado seeds present high size variability. Larger seeds, such those of the ‘Esther’ variety, are preferred when nurse seeds are used. Even though they are considered recalcitrant seeds, they are stored for propagation. The aim of this study was to evaluate the combined effect of three storage periods and three sizes of ‘Esther’ avocado seeds on vigor, in terms of electrolyte leakage, and seedling length and diameter. The experiment was conducted using a completely randomized factorial design. The factors were time in storage (10, 30 and 100 d at 5 °C and 80% relative humidity) and seed size (small, medium and large). Electrolyte leakage was evaluated as a measure of seed vigor, growth and later development of the seedlings. Seeds stored for 30 and 100 d showed the highest electrolyte leakage but produced seedlings with a larger stem diameter than 10-day-old seeds. The seeds stored for 100 d generated seedlings with stems three times wider than the seedlings stored for 10 d. The changes observed in electrical conductivity showed differences between the different sizes and storage times of seeds. It is concluded that storage time had a positive effect on the growth of ‘Esther’ avocado seedlings (length and diameter of the stem) regardless of the seed size. Electrolyte leakage was affected by seed age and seed size but did not correlate with subsequent seedling growth.

This research was conducted to evaluate the agronomic characteristics and chemical composition of Gliricidia sepium grown under different residual heights in different seasons. Experimental design used was a complete randomized block in a split-plot. Plots consisted of three residual heights (70, 90 and 110 cm) and subplots were four seasons (fall, winter, spring and summer) with four replications. There was no effect (P>0.05) of interaction between season and residual heights for agronomic characteristics. However, these features were influenced by the cutting season, with no significant effect (P>0.05) for residual height significant effects (P<0.05) were observed for DM, MM, ADF and EE in cutting seasons and residual height. Gliricidia sepium can be cut in residual height of 70 cm, with better agronomic characteristics and chemical composition in fall.

The aim of the present study was to compare the leaves of Liquidambar orientalis with leaves of Laurus nobilis and Eucalyptus globulus in terms of chemical composition and anti-methanogenic potentials using the in vitro gas production technique. Species had a significant effect on the chemical composition, gas production, methane production, metabolisable energy and organic matter digestibility of tree leaves. Crude protein (CP), neutral detergent fiber (NDF), acid detergent fiber (ADF) and condensed tannin (CT) contents of tree leaves ranged from 9.11 to 12.8, 22.49 to 35.85 and 32.76 to 49.31, 1.55 to 9.29% respectively. Gas production, methane production, metabolisable energy (ME) and organic matter digestibility (OMD) ranged from 21.72 to 31.54 ml, 2.62 ml to 4.41 ml, 6.62 to 9.24 MJ /kg DM, 41.23 to 54.84 % respectively. It is likely that leaves of Liquidambar orientalis will be more effective for methane mitigation in ruminant animals as compared with Eucalyptus globules and Laurus nobilis.
