CFD model development and validation of a thermonebulisation fungicide fogging system for postharvest storage of fruit
(Elsevier, 2012-01)Postharvest treatments of fruits in storage rooms using a fogging system is a recent development that offer a promising means to reduce the use of fungicides in the orchards, where ecological and environmental risks are ... -
Chemical and phytochemical properties and antioxidant activities of three pomegranate cultivars grown in South Africa
(Springer Verlag, 2011-02)A comparative study of chemical contents and antioxidant activities of three pomegranate cultivars (‘Arakta’, ‘Bhagwa’ and ‘Ruby’) grown in South Africa was conducted. Fresh pomegranate juice (PJ) of each cultivar were ... -
Classification of 'Granny Smith' apples with different levels of superficial scald severity based on targeted metabolites and discriminant analysis
(German Botanical Society, 2016)To study the metabolic changes in ‘Granny Smith’ apples with different severities of superficial scald, fruit were stored in normal refrigerated air (0°C, 95% RH) for 12 weeks followed by 7 d shelf-life under room conditions ... -
Early prediction of ripening and storage quality of pear fruit in South Africa
(International Society for Horticultural Science -- ISHS, 2005-04)Maturity index records for the principal pear cultivars in the two most important pear producing areas in South Africa were compiled to study the fluctuation in total soluble solids (TSS), fruit firmness and starch breakdown ... -
The effect of different rates of prohexadione-calcium and girdling on shoot growth and fruit quality when applied to different pear cultivars
(International Society for Horticultural Science -- ISHS, 2005-04)Prohexadione-Calcium (P-Ca) is a promising new shoot growth retardant that is already registered on apples in North America (Apogee®) and in Europe (Regalis®). This gibberellin biosynthesis inhibitor with limited persistence ... -
The effect of fruit maturity and storage duration on friction discolouration of Packham's Triumph and Doyenne du Comice pears
(International Society for Horticultural Science -- ISHS, 2005-04)Friction discolouration (FD) is causing the South African pear industry multi-million rand losses due to blemished fruit being rejected for the export market and being sold locally. The occurrence of FD was studied over ... -
Effect of pruning severity and branch quality on fruit set and fruit dry weight of Packham's Triumph pears (Pyrus communis L)
(International Society for Horticultural Science -- ISHS, 2005-04)The effect of dormant pruning and the quality of 2-year-old bearing units(BU) on fruit set and mean fruit dry weight of ‘Packham’s Triumph’ pears wasdetermined during the 2002/03 season. Fruit set on short BU (28 cm long) ... -
The effect of scoring during flower induction or the initiation phase on return bloom in Pyrus communis L
(International Society for Horticultural Science -- ISHS, 2005-04)The influence of scoring during the flower induction phase was investigated. Pear trees, Pyrus communis L. cv. Doyenne du Comice, Forelle and Rosemarie were used in the study, conducted in the Western Cape, South Africa. ... -
Effect of the rate and duration of forced air cooling on the quality of Imperial apricots and Pioneer and Songold plums
(Acta HorticulturaeInternational Society for Horticultural Science -- ISHS, 2005-06)Gel breakdown (GB) and overripeness (OR) remain the biggest internal Problems with Prunus armeniaca L. ‘Imperial’, which makes the biggest contribution to the total volume of apricots exported from South Africa per annum. ... -
Effects of packaging liners on cooling rate and quality attributes of table grape (cv. Regal Seedless)
(Wiley Blackwell, 2011-07)Table grapes are commonly packed in multi‐layered packages consisting of cardboard carton, plastic liners and carry bag/pouch to maintain product quality along the cold chain. Each liner is characterized by the number ... -
Evolutions of the pear training model in South Africa
(International Society for Horticultural Science -- ISHS, 2005-04)The history of pear pruning and training under the hot and dry conditions in South Africa is discussed. Due to the poor soils and the need for irrigation the move towards high-density plantings occurred with the continued ... -
Extension of the storage life of plums (Prunus salicina) using controlled atmosphere shipping
(International Society for Horticultural Science -- ISHS, 2005-06)South Africa is an important supplier of stone fruit to the northern hemisphere in the months of November to March. The voyage by sea to the main markets in the UK and Continental Europe necessitates production of cultivars ... -
The influence of storage duration and elevation of storage temperature on the development of berry split and berry abscission in vitis vinifera L. cv. Thompson seedless table grapes
(South African Society for Enology and Viticulture, 2005)Thompson Seedless grapes, packed in non-perforated low density polyethylene bags, were cold stored at -0.5°C and RH 83% for 0, 1, 2, 4 and 8 weeks. After storage at -0.5°C for these periods, the grapes were stored for ... -
Internal flesh browning of ‘Cripps’ Pink’ apple (Malus domestica Borkh.) as influenced by pre-harvest factors and the evaluation of near infrared reflectance spectroscopy as a non-destructive method for detecting browning
(Stellenbosch : Stellenbosch University, 2015-03)ENGLISH ABSTRACT: The successful marketing of ‘Pink Lady’™ apples produced in South Africa is under pressure due to internal flesh browning (IFB) development. IFB incidence is increased by long term controlled atmosphere ... -
Investigating the performance of thermonebulisation fungicide fogging system for loaded fruit storage room using CFD model
(Elsevier, 2012-03)To study the operation of postharvest storage fungicide fogging systems, a CFD model was used. The modelling was based on an Eulerian–Lagrangian multiphase flow model. The effect of air circulation rate, circulation ... -
