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, ... -
Floral induction in Eucalyptus nitens (Deane and Maiden) Maiden in South Africa.
(2003)Eucalyptus nitens (Deane & Maiden) Maiden is an important, commercial eucalypt planted predominantly for pulpwood in several southern hemisphere countries. In South Africa, the erratic and sparse flowering habit of E. ... -
Factors affecting mesocarp discolouration severity in 'Pinkerton' avocados (Persea americana MILL.)
(2005)The susceptibility of the 'Pinkerton' avocado cultivar to mesocarp discolouration, after storage, has seriously threatened its export from South Africa. This disorder has proven to be complex, requiring a better understanding ... -
Gladiolus scabridus - the road to conservation and commercialisation.
(2005)There is at present a growing concern and awareness of the endangered status of many indigenous South African plants in the wild, a number of which have potential for commercial production. One such example is Gladiolus ... -
Development of a sulphur free litchi storage protocol using sealed polypropylene bags.
(2006)The use of sulphur as a method of postharvest disease control and colour retention in litchis is soon to be restricted by the European Union. It is therefore essential that new postharvest treatments and packaging ... -
Investigation into the feasibility of a dairy processing enterprise through action research with a group of women from an LRAD project.
(2007)Poverty is caused by inadequate income. Effective assistance to small-scale enterprises may benefit the urban and rural poor. Small enterprises have the potential to create employment, reduce poverty and support sustainable ... -
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. ... -
Special carbohydrates of avocado : their function as 'sources of energy' and 'anti-oxidants'.
(2009)There is increasing interest in special heptose carbohydrates, their multifunctional roles from a plant physiological view point in fruit growth and development as well as in the whole plant in general due to their potential ... -
Effect of methyl jasmonate and salicyclic acid on chilling injury of 'eureka' lemons.
(2010)South Africa is the second largest exporter of citrus fruit in the world. There has recently emerged a strong demand for lemons in the world market due to their nutritional value, culinary and non-culinary uses. During ... -
Effect of postharvest silicon application on 'hass' avocado (Persea americana Mill.) fruit quality.
(2010)The South African avocado industry is export-orientated with forty percent of total production sold overseas. The avocado fruit is a highly perishable product with a relatively high rate of respiration which results in ... -
Horticultural manipulation techniques to improve yield, fruit size and quality in 'Wai Chee' litchi (Litchi chinensis Sonn.)
(2010)In South Africa, a shortage of litchi cultivars to expand the very short harvesting period has seriously threatened the viability of the local export orientated Litchi Industry. Only two cultivars have dominated commercial ... -
Studies of the micronutrients zinc, manganese and silicon in cucumbers (Cucumis sativus)
(2010)Zinc and manganese have long been considered as essential micronutrients to plant growth, yet the interactions of the two nutrients on growth and development of plants have not been elucidated in their entirety. Silicon ... -
Management of avocado postharvest physiology.
(2011)Avocados are an important horticultural crop in South Africa, especially in the provinces of KwaZulu-Natal, Mpumalanga and Limpopo. The distance to traditional export markets, phytosanitary restrictions to lucrative ... -
Enhancement of 'Hass' avocado shelf life using ultra-low temperature shipping or 1-MCP treatment and cold chain management.
(2011)Avocados are becoming an increasingly important crop in South Africa, where the main producing areas include Limpopo, Mpumalanga and KwaZulu-Natal provinces. The South African avocado industry faces considerable challenges ... -
Effect of systemic resistance inducers applied pre- and postharvest for the development of a potential control of colletotrichum Gloeosporioides on Persea Americana (Mill.) CV 'Fuerte'.
(2012)Avocados are one of the major food sources in tropical and subtropical regions and are an important horticultural crop in South Africa. Avocados are exported over long distances and may have storage times of up to 30 or ... -
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 ... -
Influence of stockplant management on yield and subsequent rooting of cuttings of cold-tolerant Eucalyptus grandis x E. nitens clones.
(2012)Clones of the Eucalyptus grandis x Eucayptus nitens (GN) hybrids were produced and selected through the CSIR‟s breeding programmes for colder plantation sites in South Africa. Some GN clones consistently exhibit high and ... -
Methyl jasmonate and salicylic acid enhance chilling tolerance in lemon (citrus limon) fruit.
(2013)South African ‘Eureka’ lemon fruit must be exposed to chilling temperatures (± 0.6°C) as a mandatory quarantine treatment against insect pests for all its overseas markets. Chilling lemon fruit at such temperatures may ... -
Yield and quality parameters of tomato cultivars as affected by different soilless production systems and beneficial micro-organisms.
(2013)Most tomato cultivars used for commercial food production are imported into South Africa. Optimal growing conditions for these specific cultivars need to be determined, as wrong cultivar choices can lead to great financial ... -
