Rapid methods for extracting and quantifying phenolic compounds in citrus rinds
(Wiley Open Access, 2016)Conventional methods for extracting and quantifying phenolic compounds in citrus rinds are time consuming. Rapid methods for extracting and quantifying phenolic compounds were developed by comparing three extraction solvent ... -
Mating compatibility and competitiveness between wild and laboratory strains of Eldana saccharina (Lepidoptera : Pyralidae) after radiation treatment
(Florida Entomological Society, 2016)The efficacy of the sterile insect technique (SIT) applied as part of area-wide integrated pest management (AW-IPM) depends on efficient transfer of sperm carrying dominant lethal mutations from sterile males to wild ... -
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 ... -
Berry abscission in vitis vinifera L. cv. Waltham Cross : changes in abscission-related factors during berry development
(South African Society for Enology and Viticulture, 2005)During the 1999 season, changes in total soluble solids (TSS), titratable acids (TA), pedicel diameter, berry diameter, berry mass and fruit removal force (FRF) were determined at biweekly intervals from 27 until 111 days ... -
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 ... -
Stability of total phenolic concentration and antioxidant capacity of extracts from pomegranate co-products subjected to in vitro digestion
(BioMed Central, 2016-09)Background: Co-products obtained from pomegranate juice processing contain high levels of polyphenols with potential high added values. From value-addition viewpoint, the aim of this study was to evaluate the stability of ... -
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 ... -
Physiological responses of pears to exogenous ethylene and pre-harvest factors influencing post-harvest quality with reference to 'Forelle' and 'Packham's Triumph' pears
(Stellenbosch : Stellenbosch University, 2000-04)ENGLISH ABSTRACT: The major sites for fruit ripening and softening are found in the middle lamella where enzymatic and non-enzymatic mechanisms seem to degrade pectin polymers to a more soluble state and in the primary ... -
Use of evaporative cooling to improve ' Rosemarie' and ' Forelle' pear fruit blush colour and quality
(International Society for Horticultural Science -- ISHS, 2005-04)In Pyrus communis ‘Rosemarie’, a potentially lucrative blushed pear cultivar, poor fruit colour has been ascribed to pre-harvest red colour loss during periods of high temperature. High temperatures combined with high ... -
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. ... -
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 ... -
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 ... -
Temperature variances in a 12 m integral reefer container carrying plums under a dual temperature shipping regime
(International Society for Horticultural Science -- ISHS, 2005-07)The South African plum industry is an important supplier of fresh fruit to the northern hemisphere from December to April. Extensive use is made of a dual- temperature shipping regime, which is a form of intermittent ... -
Status of the pear industry in Africa, with specific reference to South Africa
(Acta Horticulturae, 2005-04)In the context of global production, Africa as a continent is a very small producer of Pyrus communis pears, with roughly 3% of global hectares and production. South Africa produces 56% of Africa’s total crop, followed by ... -
Reproductive bud development of pears (Pyrus communis L.) with emphasis on the bourse shoot
(International Society for Horticultural Science -- ISHS, 2005-04)For consistent yields in pear fruit production, knowledge of the development of the reproductive bud is required. The aim of this study was to gain more insight into the development of the primordial bourse shoot. The ... -
Red colour development and loss in pears
(International Society for Horticultural Science -- ISHS, 2005-04)The endogenous and environmental regulation of red colour development in blushed and fully red pears is reviewed. Colour development in pears has an underlying developmental component. Generally, highest anthocyanin c ... -
Post-harvest control of the grain chinch bug Macchiademus diplopterus (Heteroptera: Lygaiedae) on pears in the Western Cape Province, South Africa
(Acta Horticulturae, 2005-04)The grain chinch bug (GCB) M. diplopterus is endemic to the Western Cape and as such is classified as a quarantine pest. The aim of this project was to evaluate post-harvest methods of control to ensure that packed fruit ... -
Postharvest calyx retention of citrus fruit
(Acta Horticulturae, 2005-06)Abscission is an active developmental process occurring at the abscission zone of the fruit peduncle. The target cells in the abscission zone, which are involved in the process of separation, are located in the separation ... -
