Abscisic acid metabolism in a Citrus Sinensis flavedo enzyme system.
(1998)This research project had its major objective the unequivocal demonstration that the plant growth regulator, abscisic acid could be produced in vitro from labelled precursors. In addition, this project was intended to ... -
Antioxidants composition of moringa (moringa oleifera lam) in different plant organs.
(2015)Moringa oleifera Lam. is a versatile plant with various benefits; different parts of the plant have different pharmacological activity such as flavonoid, alkaloids, phenol, and carotenoids. The aim of the seed study was ... -
Aspects of improving cold hardiness of tomato (Lycopersicon esculentum) var. Rossol.
(2004)Tomatoes, particularly those of the determinate type, are one of the most popular vegetables in the East African country Eritrea. The crop is a source of income to small farm operators as well as commercial growers, and ... -
Banana (Musa AAA; Cavendish sub-group) cultivar/density trials in three bioclimatic groups on the north coast of KwaZulu-Natal.
(1997)The North Coast of KwaZulu-Natal is a relatively new banana production area, for which there is an absence of local norms, specifically for choice of cultivar and population density. Three cooperative split-plot banana ... -
The biochemical basis of colour as an aesthetic quality in Citrus sinensis.
(2001)The development of fruit colour in the sweet orange (Citrus sinensis) is a cultivar characteristic affected by climate and environment. Although external colour is not always an indication of internal quality or maturity, ... -
Biosynthetic origin of abscisic acid in ripening avocado fruit.
(2000)Mesocarp of ripening avocado fruit incorporated label from [2-(14)C]mevalonolactone, [1-(14)C] acetic acid, [1-(14)C] glucose and [1 -(14)C] pyruvate into ABA, although incorporation from mevalonolactone was significantly ... -
Bowen ratio and surface temperature techniques for measuring evaporation from cabbages.
(1997)Good irrigation water management requires accurate, automated, non-destructive and simple techniques to measure crop water consumption. The actual evaporation from a cabbage crop was measured using the Bowen ratio energy ... -
The combined effects of daylength and temperature on onion bulb when grown under greenhouse environment.
(2017)Abstract available in PDF file. -
A comparative study of antioxidant potentials of some leafy vegetables : emphasis on African leafy vegetable and exotic vegetables.
(2014)Due to malnutrition and food insecurity problem around the globe, mainly in developing countries, cheap nutritional food sources are required. In South Africa, a large proportion of the population is considered “poor” and ... -
A comparative study on carbohydrates and antioxidants of indigenous crop black jack (Bidens pilosa L.) and selected commercial vegetable crops.
(2014)The adequate consumption of African leafy vegetables has been closely associated with a strong reduction of chronically disease such as cancer, diabetes and cardiovascular diseases. The health benefits provided by African ... -
Development of a sulphur free litchi storage protocol using sealed polypropylene bags.
(2006)The use of sulphur as a method of postharvest disease control and colour retention in litchis is soon to be restricted by the European Union. It is therefore essential that new postharvest treatments and packaging ... -
The development of indigenous marula (sclerocarya birrea) fruit leather : effect of drying temperature and sugar concentration on the drying characteristics, physico-chemical and consumer sensory properties of marula fruit leathers.
(2016)Fruits indigenous to African countries are highly recognised and valued by rural communities for food security purposes. An examples of such fruits include but not limited to marula fruits (Sclerocarya birrea), which is ... -
Effect of coloured shade nets and plastics on Eucalyptus hybrid mini-hedge stock plant morphology and subsequent cuttings rooting potential.
(2014)Eucalyptus grandis (W. Hill) × E. nitens (Maiden) (G × N) clonal hybrids are bred to produce trees more cold-tolerant than E. grandis alone due to the cold-resistant E. nitens parent. Some of these selected hybrid clones ... -
Effect of elevated CO2 concentration on growth, development and postharvest characteristics of sweetcorn (Zea mays L. var. saccharata)
(2022)Abstract available in PDF. -
Effect of methyl jasmonate and salicyclic acid on chilling injury of 'eureka' lemons.
(2010)South Africa is the second largest exporter of citrus fruit in the world. There has recently emerged a strong demand for lemons in the world market due to their nutritional value, culinary and non-culinary uses. During ... -
The effect of moringa leaf extract (MLE) on growth and development, mineral composition and antioxidant properties of radish (raphanus sativus) and green beans (phaseolus vulgaris)
(2019)Besides enhancing food production, one of the major challenges of the agricultural sector is to provide essential minerals and nutrients to humans for the maintenance of a healthy body, not only from a caloric perspective, ... -
Effect of postharvest silicon application on 'hass' avocado (Persea americana Mill.) fruit quality.
(2010)The South African avocado industry is export-orientated with forty percent of total production sold overseas. The avocado fruit is a highly perishable product with a relatively high rate of respiration which results in ... -
