Evaluation of maturity parameters of 'Fuerte' and 'Hass' avocado fruit.
(2014)Avocado fruit is one of the most important horticultural crops produced in South Africa. The fruit does not give obvious indication of maturity as it does not ripen as long as it remains attached to a tree. Harvesting ... -
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 ... -
Floral induction in Eucalyptus nitens (Deane and Maiden) Maiden in South Africa.
(2003)Eucalyptus nitens (Deane & Maiden) Maiden is an important, commercial eucalypt planted predominantly for pulpwood in several southern hemisphere countries. In South Africa, the erratic and sparse flowering habit of E. ... -
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 ... -
Postharvest maintenance of the shelf life and quality attributes of banana and papaya.
(2003)Banana and papaya are two commonly grown fruits of the tropical regions of the world. Like most tropical climacteric fruits, these fruits have a short shelf life and deteriorate rapidly after harvest. This becomes more ... -
Means of improving colour expression in pepper fruit.
(2003)Colour is a characteristic that makes fruit appealing to the consumer, hence, is a prime factor when (s)he chooses to buy certain horticultural commodities. If colour is unappealing, consumers tend to ignore other quality ... -

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 ... -
In vitro culture of avocado : a model system for studying the biochemistry of fruit growth.
(2000)The avocado (Persea americana Mill.) is considered by many to be a horticultural problem. Cultivars in use today have several drawbacks associated with yield, disease susceptibility and fruit quality. Breeding programs ... -
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, ... -
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 ... -
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 ... -
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 ... -
Effectiveness of pre- and postharvest silicon and phosphorous acid applications in inhibiting Penicillium digitatum on citrus fruit.
(2014)Citrus is, by tonnage, globally the most-produced fruit. Although technological advances have greatly improved storage life and quality of citrus, postharvest decay remains a major problem. Penicillium digitatum (green ... -
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 ... -

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 ... -
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 ...
