Effect of coloured shade nets and plastics on Eucalyptus hybrid mini-hedge stock plant morphology and subsequent cuttings rooting potential.

Gilbert, Donna Louise. (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 ...

A comparative study of antioxidant potentials of some leafy vegetables : emphasis on African leafy vegetable and exotic vegetables.

Mathe, Sakhile. (2016-01-21)

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 ...

Evaluation of maturity parameters of 'Fuerte' and 'Hass' avocado fruit.

Olarewaju, Olaoluwa Omoniyi. (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 ...

A comparative study on carbohydrates and antioxidants of indigenous crop black jack (Bidens pilosa L.) and selected commercial vegetable crops.

Mbokazi, Nelani Simon. (2015-10-30)

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 ...

Effectiveness of pre- and postharvest silicon and phosphorous acid applications in inhibiting Penicillium digitatum on citrus fruit.

Mkhize, Nopayi. (2015-10-21)

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 ...

Vapour heat treatment of 'Hass' and 'Fuerte' avocado (Persea americana Mill.) fruit for extending storage life.

Weller, Philip Lawrence. (2014-12-24)

In an attempt to extend storage life of 'Hass' and 'Fuerte' avocado {Persea americana Mill.) fruit postharvest vapour heat treatments were used. Vapour heat treatment temperature regimes were 36, 38, 40 and 42°C for ...

Some aspects of cold storage of 'Fuerte' avocados (Persea americana Mill.) grown in the Natal midlands.

Donkin, Derek John. (2014-12-24)

The South African avocado industry is largely export orientated and export by sea to European markets necessitates cold storage for up to 4 weeks at temperatures around 5.5°C. Avocado fruit is subject to chilling injury ...

Bowen ratio and surface temperature techniques for measuring evaporation from cabbages.

Lukangu, Gastao. (2014-12-24)

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 ...

Nutrition of containerised pine (Pinus patula Schlecht. et Cham.) seedlings grown in pine bark.

Jarvel, Leanne. (2014-12-24)

Increasing demands for timber and timber products have resulted in the rapid expansion of containerised forestry seedling production. The lack of available information on pine seedling fertilization has forced nurserymen ...

A prediction model to determine the cross-pollination ability of Citrus spp.

Barry, Graham H. (2014-12-24)

Due to a greater emphasis having been placed on seedlessness by citrus consumers, a need developed in the southern African citrus industry to avoid unwanted cross-pollination and hence seediness. There was a paucity of ...

The biochemical basis of colour as an aesthetic quality in Citrus sinensis.

Oberholster, Renate. (2014-12-23)

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, ...

Banana (Musa AAA; Cavendish sub-group) cultivar/density trials in three bioclimatic groups on the north coast of KwaZulu-Natal.

Lagerwall, Gary Brian. (2014-12-23)

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 ...

Abscisic acid metabolism in a Citrus Sinensis flavedo enzyme system.

Kalala, Maloji. (2014-12-23)

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 ...

Soil boron application for the alleviation of boron deficiency of avocado (Persea americana Mill.) in the KwaZulu-Natal Midlands.

Bard, Zac Jon. (2014-12-22)

The avocado tree's requirement for additional boron in B deficient soils has traditionally been met solely by foliar sprays in South Africa. Since boron is regarded as poorly phloem translocated in most plants including ...
