Non-destructive determination of pre-symptomatic biochemical markers for Peteca spot and evaluation of edible coatings for reducing the incidence of the disorder on ‘Eureka’ lemons
(2019)International markets that import citrus fruit from South Africa have imposed regulations that involve cold sterilization at low temperatures, which cause physiological disorders such as peteca spot in lemon. The aim of ... -
Nutrition of containerised pine (Pinus patula Schlecht. et Cham.) seedlings grown in pine bark.
(1996)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 ... -
Optimisation of propagation methods in Prunus persica (L.) Batsch.
(2001)Propagating methods for peach (Prumis persica L. Batsch.) are currently limited to the use of seeds or cuttings. Most of the rootstocks commonly used for establishing peach trees commercially originate from a narrow genetic ... -
Optimization of flower and seed crop production in temperate eucalyptus orchards in South Africa through site selection and environmental manipulation.
(2014)Temperate eucalypts are an important part of the commercial forestry landscape in South Africa, comprising approximately 50% of the total Eucalyptus planted area. The majority of the commercial temperate eucalypts grown ... -
Optimization, validation and application of radioimmunoassays for plant growth substances in avocado (Persea americana Mill.) fruits.
(1984)The objective was to develop, optimize and validate radioimmunoassays (RIA) for several plant growth substances (PGS) and then apply the RIA's to determine PGS trends in 'Fuerte' avocado fruits from fruit set to fruit ... -
Ovule and seed studies in relation to fruit growth in Carica papaya L. cl. honey gold.
(1979)No abstract available. -
Physiological and biochemical effect of biostimulants on Abelmoschus esculentus (L.) and Cleome gynandra (L.)
(2021)Abelmoschus esculentus (L.) and Cleome gynandra (L.) are neglected plants, often collected from the wild, with dual benefits of nutritional and medicinal values, especially in rural communities. Biostimulants are well-known ... -
Plant hormone homeostasis and the control of 'hass' avocado fruit size.
(2002)The 'Hass' avocado produces two distinct phenotypically different populations of fruit, i.e. normal and small fruit. The small fruit variant is characterized by early seed coat senescence that results in arrested growth, ... -
Post-harvest manipulation of rind colour in 'Mauritius' litchi (Litchi chinensis Sonn.) fruit.
(1996)Litchi fruit are non-climacteric, and are able to endure relatively low storage temperatures compared to other subtropical fruits. Unfortunately however, the litchi rind is relatively thin and lacks a thick, durable ... -
Post-phloem transport and metabolism of sucrose in avocado.
(2001)In South Africa, and in several other sub/tropical countries, the avocado represents a commercially important crop. Very little is currently understood about the metabolism of sugars in this fruit. The variety 'Hass' is ... -
Postharvest maintenance of the shelf life and quality attributes of banana and papaya.
(2003)Banana and papaya are two commonly grown fruits of the tropical regions of the world. Like most tropical climacteric fruits, these fruits have a short shelf life and deteriorate rapidly after harvest. This becomes more ... -
Postharvest technologies for predicting and reducing susceptibility of ‘Marsh’ grapefruit (Citrus paradisi MacFad.) to rind pitting disorder.
(2019)Citrus fruit is globally one of the most important fruit due to their nutritional value and sensorial attributes, however, they were susceptible to various postharvest disorders, especially during shipping period. ... -
The potential of post-harvest potassium silicate dips to mitigate chilling injury on citrus fruit.
(2012)The South African Citrus Industry is the second largest exporter of citrus, after Spain. The industry is under pressure to supply high quality fruit as well as to expand into new, high paying markets. However, high paying ... -
Potential of pre-and postharvest illumination of cherry tomato, a climacteric fruit, to reduce the ripening period and enhance yield and quality while maintaining shelf life.
(2017)Tomato (Solanum lycopersicum) is the most-consumed horticultural commodity worldwide because it is diverse in use, attractive and contributes significantly to the health and nutrition of humans. There are many different ... -
Pre- and post-harvest response of selected indigenous leafy vegetables to water stress.
(2018)South Africa has wide diversity of African leafy vegetables (ALVs) rich in nutrients and adapted to marginal production. However, there is limited availability of ALVs in South Africa due to lack of cultivation owing to ... -
A prediction model to determine the cross-pollination ability of Citrus spp.
(1995)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 ... -
A preliminary study on the effect of climatic conditions and fruit mineral concentration on the development of lenticel damage in 'Tommy Atkins' and 'Keitt' mangos (Mangifera indica L.) and rind pitting in 'Benny Valencia' oranges (Citrus sinensis).
(2008)The South African fresh fruit industry is a significant exporter, accounting for approximately 45% of the country’s agricultural exports. Of the total exported fruit in the 2005/06 season, 60% was subtropical fruit. ... -
Rapid monitoring and quantification of unripe banana flour adulteration using visible-near infrared spectroscopy.
(2021)A general lack of strict regulations in South Africa to monitor processed foodstuff increases chances of unfair producers and traders to intentionally mislabel and adulterate high valued food products with inferior ... -
Responses of cabbage (brassica oleracea var. capitata), swiss chard (beta vulgaris), and pepper (capsicum annuum) seedlings to growing media pre-enriched with vermicompost.
(2021)Seedling production is mainly achieved by using growing media as substrates; most nurseries in South Africa use pine bark and vermiculite in their ‘in-house’ medium. For the growing medium to effectively anchor and yield ...
