Optimised extraction and preliminary characterisation of mannoproteins from non-saccharomyceswine yeasts
(MDPI, 2021-04-22)The exogenous application of yeast-derived mannoproteins presents many opportunities for the improvement of wine technological and oenological properties. Their isolation from the cell wall of Saccharomycescerevisiae has ... -
Canola is injured by in‐row nitrogen placement associated with disc openers, but not by tine openers
(Crop Science Society of America, 2020)Seed drills are used in no‐tillage systems to place seed directly in soil. Various furrow openers exist, each with unique seed and fertilizer placement characteristics, particularly positioning of fertilizer in relation ... -
A prospectus for sustainability of rainfed maize production systems in South Africa
(Crop Science Society of America, 2020)The rainfed maize (Zea mays L.) production systems of South Africa require an integrated approach to use the limited soil available water more efficiently, and to increase system productivity and sustainability. The soils ... -
A comparison of experimental designs for cultivar evaluations
(Taylor and Francis, 2020)Spatial heterogeneity and the lack of clear or significant treatment responses in agricultural field experiments complicates recommending the most suitable cultivar(s) to producers for a specific area. Increased attention ... -
Effect of the illumination angle on NDVI data composed of mixed surface values obtained over vertical‐shoot‐positioned vineyards
(MDPI, 2021-02-25)Accurate quantification of the spatial variation of canopy size is crucial for vineyard management in the context of Precision Viticulture. Biophysical parameters associated with canopy size, such as Leaf Area Index (LAI), ... -
An overview of mites on grapevine and the discovery of a new phytoseiidae species; typhlodromus (typhlodromus) spiceae
(South African Society for Enology and Viticulture, 2021)The common grapevine (Vitis vinifera L.) is the main species used for wine making, with South Africa being one of the top wine exporting countries. Grapevine is vulnerable to a range of pests, includingmites. We present ... -
Towards the validation of high-throughput sequencing (HTS) for routine plant virus diagnostics: measurement of variation linked to HTS detection of citrus viruses and viroids
(BioMed Central, 2021-03-22)Background: High-throughput sequencing (HTS) has been applied successfully for virus and viroid discovery in many agricultural crops leading to the current drive to apply this technology in routine pathogen detection. ... -
Combined effect of dietary protein, ractopamine, and immunocastration on boar taint compounds, and using testicle parameters as an indicator of success
(MDPI, 2020-11-14)This study investigates the combined effect of immunocastration, dietary protein level (low, medium or high) and ractopamine hydrochloride supplementation (0 or 10 mg/kg) on the adipose concentrations of androstenone, ... -
Application of gum arabic and methyl cellulose coatings enriched with thyme oil to maintain quality and extend shelf life of “Acco” pomegranate arils
(MDPI, 2020-12-01)The effects of gum arabic (GA; 1.5% w/v) and methyl cellulose (MC; 1% w/v) enriched with thyme oil (TO; 0.25 and 0.5% v/v) on the quality of “Acco” pomegranate arils were studied. Coating treatments, namely, MC, MC + ... -
Application of fat-tailed sheep tail and backfat to develop novel warthog cabanossi with distinct sensory attributes
(MDPI, 2020-12-08)This study compared the use of pork backfat (PF) and fat-tailed sheep tail and backfat (SF) on the physicochemical, fatty acids and sensory attributes of warthog cabanossi. There were no differences between weight loss ... -
The effects of postharvest treatments and sunlight exposure on the reproductive capability and viability of Phyllosticta citricarpa in citrus black spot fruit lesions
(MDPI, 2020-12-21)Citrus black spot (CBS) is caused by Phyllosticta citricarpa, which is classified as a quarantine organism in certain countries whose concerns are that CBS-infected fruit may be a pathway for introduction of the pathogen. ... -
The 3Ps (Profit, Planet, and People) of sustainability amidst climate change : a South African grape and wine perspective
(MDPI, 2021-03-08)Conventional agriculture has made the search for sustainability urgent, more so with regards to climate change. This has extended to the grape and wine industry, an important industry in South Africa in terms of labor ... -
A review of fire management practices in African savanna-protected areas
(AOSIS, 2021)The level of understanding of the ecological effects of fires has improved over the past century, but comprehensive information on the practical application of fire remains restricted to a few well-studied areas, and ... -
Grapevine leaf application of steinernema yirgalemense to control planococcus ficus in semi-field conditions
(South African Society for Enology and Viticulture, 2019)The vine mealybug, Planococcus ficus Signoret (Hemiptera: Pseudococcidae), is a key insect pest of South African grapevine. The ability of mealybugs to avoid or resist the action of chemical pesticides has led to the ... -
Grape must profiling and cultivar discrimination based on amino acid composition and general discriminant analysis with best subset
(South African Society for Enology and Viticulture, 2019)The present study aimed to elucidate the amino acid profile of a number of grapevine cultivars relevant to the South African wine industry using 738 grape must samples obtained during the 2016 and 2017 harvests. Proline ... -
Impact of time, oxygen and different anthocyanin to tannin ratios on the precipitate and extract composition using liquid chromatography-high resolution mass spectrometry
(South African Society for Enology and Viticulture, 2019)Wine colour and phenolic stability over time are influenced by the amount and nature of phenolics in young wines. The ratio between different phenolic compounds can also be determinant in the colour and phenolic development ... -
Research note : effect of light quality on fruit growth, composition and the sensory impact of the wines
(South African Society for Enology and Viticulture, 2019)The stage at which grapes are harvested has an influence on the aromatic and phenolic composition of the berries and the resulting wines. The aim of this study was to evaluate wines harvested sequentially as outlined in ... -
Effects of abiotic factors on phenolic compounds in the grape berry – a review
(South African Society for Enology and Viticulture, 2019)Grape berry phenolic compounds are widely described in literature. Phenolics can be divided into two main groups: flavonoids and non-flavonoids, of which the flavonoids are the most important. The two bestknown groups of ... -
Profiling potentially smoke tainted red wines : volatile phenols and aroma attributes
(South African Society for Enology and Viticulture, 2019)Malodourous compounds, including volatile phenols (VPs) are frequently found at concentrations below their odour thresholds in wine, and may therefore be considered to present no threat to wine quality. Most investigations ... -
