Abstract:

Thesis (MSc)--Stellenbosch University, 2015.<br>ENGLISH ABSTRACT: Thinning is an important practice in pome fruit production which aims to ensure an optimal yield of high quality, large sized fruit as well as an adequate return bloom. In South Africa, pome fruit thinning is generally done by means of chemicals, with follow-up hand thinning. When thinning is effective, set and thus the hand thinning requirement should be reduced. This is important as labor cost associated with hand thinning is high and continually rising. Chemical thinning is weather dependent and can be environmentally harmful

A kaolin product, M-97- 009 (100% kaolin), originally developed for insect control, was evaluated for its efficacy in controlling sunburn on pome fruit. Trials were conducted over two seasons in two different areas of the Western Cape, South Africa. During the first season, 'Royal Gala', 'Fuji' and 'Granny Smith' apples were evaluated in the Koue Bokkeveld. The kaolin was mixed with water and applied to the trees by means of a hand-gun regularly throughout th

The challenges of climate change, disease incidence, distant markets and fluctuating consumer preferences necessitate new cultivars. The Agricultural Research Council (ARC) Infruitec-Nietvoorbij conducts a breeding programme aimed at developing new cultivars that are well adapted, resistant to pests and diseases and good storage potential.

Abstract:

Ethylene antagonists offer an effective way to prevent the deleterious effects of ethylene in climacteric fruits. 1-Methylcyclopropene, 1-hexylcyclopropene, (S)-(-)- limonene and trans-cinnamaldehyde were evaluated as ethylene antagonist to extend the storage life of apple and pear fruits. 1-Methylcyclopropene was most efficient followed by 1-HCP, (S)-(-)-limonene and trans-cinnamaldehyde in suppressing and delaying climacteric ethylene production, extending cold and controlled atmosphere storage life and maintaining fruit quality depending upon cultivar and storage period.

Thesis (MScAgric (Plant Pathology))--University of Stellenbosch, 2010.<br>ENGLISH ABSTRACT: A survey was undertaken on apple and pear trees in the Western Cape Province to determine the aetiology of trunk diseases with reference to trunk diseases occurring on grapevine. Grapevine trunk diseases cause the gradual decline and dieback of vines resulting in a decrease in the vine’s capability to carry and ripen fruit. In recent years, viticulture has been expanding into several of the well established pome fruit growing areas. The presence of trunk pathogens in pome fruit orchards may affect

Post-harvest pathogens were monitored and quantified throughout the growing season in four apple orchards in the Okanagan Valley, BC in 2007 and 2008.

Consequently, the complex needs of maintaining the cold chain of perishable produce and the considerable variations in packaging designs have made it challenging to find an optimal ventilated package and stackin
