The production of high quality fruit that meet international standards is of vital importance to the South African fruit industry. Detrimental climatic conditions are forcing producers to examine alternate production ...
Aroma profiles and non-destructive determination of quality parameters of Japanese plums (Prunus salicina Lindl.)

Louw, Esme Denise (Stellenbosch : University of Stellenbosch, 2011-03)

ENGLISH ABSTRACT: Plums with good taste, aroma and eating quality lead to repeat purchases and sustained demand. Taste includes non-volatile compounds, e.g. sugars and acids, and has been well researched to meet the consumers’ ...
Cell wall compositional differences between mealy and non-mealy ‘Forelle’ pear (Pyrus communis L.)

Crouch, Elke Monika (Stellenbosch : University of Stellenbosch, 2011-03)

ENGLISH ABSTRACT: Mealiness, a soft, dry textural disorder of ‘Forelle’ pear (Pyrus communis L.), is a problem for the South African fruit export industry. Soft, dry textural disorders seem to be related to changes in ...
Chemical thinning of European pear cultivars (Pyrus communis L.)

Chabikwa, Tinashe Gabriel (Stellenbosch : Stellenbosch University, 2008-12)

Chemical thinning of fruit trees has become a central management practice for ensuring high fruit quality at harvest and return bloom the following season. Three trials were conducted in the 2004/5, 2006/7 and 2007/8 ...
Cold storage of Leucospermum cutflowers and Leucadendron greens

Graham, Shelly (Stellenbosch : Stellenbosch University, 2005-12)

ENGLISH ABSTRACT: Quality of certain Leucospermum and Leucadendron cultivars after approximately 21 days shipping has been reported to be substandard due to ‘drying out’ of leaves and, in the case of Leucadendrons, ...
Colour dynamics in Leucadendron

Schmeisser, Michael (Stellenbosch : University of Stellenbosch, 2010-12)

ENGLISH ABSTRACT: The bright colouration of involucral leaves in Leucadendron is unfortunately transient in nature. Undesirable colour changes render this cut flower unmarketable, resulting in a considerable loss of profit. ...
Comparative financial efficiency of training systems and rootstocks for 'Alpine' nectarines (Prunus persica var. nectarine)

Maree, Waldo J. (Stellenbosch : University of Stellenbosch, 2007-03)

Most nectarine orchards in South Africa are currently planted at a distance of 4 x 1.5 m (2 500 trees/ha). These trees are mainly sylleptically trained to a central leader, although many producers also use the proleptic ...
Consumer reference (of red-fleshed apples) an quantification of quality related traits, particularly skin and flesh colour, in apple breeding families

Thovhogi, Fhatuwani (Stellenbosch : University of Stellenbosch, 2009-12)

ENGLISH ABSTRACT: In order to develop a novel pink- or red-fleshed apple for the fresh consumer market,the red-fleshed genotype, ‘KAZ 91’ (Malus niedzwetzkyana Dieck.), was crossed with ‘Meran’ (M. domestica Borkh) at the ...
Cooling and shipping studies on table grapes (Vitis vinifera L.)

Ngcobo, Mduduzi E. K. (Stellenbosch : Stellenbosch University, 2008-03)

ENGLISH ABSTRACT: Fruit quality is the most important factor that determines prices for the fruit in the international markets. Although different consumers perceive quality differently there are quality variables that ...
Creasing studies in citrus

Phiri, Zanele Penelope (Stellenbosch : University of Stellenbosch, 2010-03)

ENGLISH ABSTRACT: Creasing, also known as albedo breakdown, is a preharvest disorder that affects the albedo of citrus fruit causing creases on the surface of the fruit. It is a recurrent problem in Navel and Valencia ...
Ecophysiological responses of citrus trees and sugar accumulation of fruit in response to altered plant water relations

Prinsloo, Johan Andries (Stellenbosch : University of Stellenbosch, 2007-03)

This study was undertaken to quantify some of the effects of daily fertigation on ecophysiological responses in citrus trees (Citrus spp.). Initial research was conducted to optimise and standardise the sampling procedure ...
Effect of biological amendments on soil microbial properties and performance of pome fruit trees

Van Schoor, Louise (Stellenbosch : Stellenbosch University, 2009-12)

ENGLISH ABSTRACT: The global movement in agriculture is towards more environmentally friendly, sustainable production practices, since the role of soil microbial functions in ensuring crop production and soil fertility has ...
The effect of canopy position on the fruit quality and consumer preference of apples

Hamadziripi, Esnath Tatenda (Stellenbosch : Stellenbosch University, 2012-12)

ENGLISH ABSTRACT: We aimed to determine how canopy microclimate influences fruit quality and consumer preference in apples. Our postulate was that consumer preference would be higher for the taste, but not necessarily ...
The effect of different water and nutrient management strategies on the calcium content in apple fruit

Joubert, Jorika (Stellenbosch : University of Stellenbosch, 2007-03)
