Maintenance of carbon 7 sugar levels and effect on ripening of 'fuerte' and 'hass' avocado (Persea americana Mill.) fruit.
(2018)Avocado fruit are susceptible to a large variety of disorders. These disorders may be a result of an inability of the mesocarp tissue to counteract or tolerate postharvest stress. The C7 sugars D-mannoheptulose and perseitol ... -
Maize crop growth and development related to solar radiation.
(1976)The interception and reflection of solar radiant energy by maize crops was measured at Cedara using tube solarimeters. From the measured data the amount of PHAR that was intercepted was related to the L value of the ... -
Maize root rot in South Africa.
(1995)Numerous fungal species are known to infect maize roots and eventually cause rot. The spectrum of fungi differs over localities as well as their relative frequencies. Fungi isolated from discoloured root tissue and root ... -
Malaria risk in the Lubombo spatial development initiative area : a perceptual analysis and representation using geographical information systems.
(2003)Tourism is the world's largest earner of foreign currency. It brings an estimated R20 billion a year into the South African economy, second only to the manufacturing and mining industry in its contribution to the Gross ... -
Management and regulation of rural land use : a model for traditional land tenure systems in KwaZulu-Natal.
(2000)South Africa is confronted by a number ofproblems which include: a high and rapidly increasing population, conditions of poverty, hunger, illiteracy, unemployment, and a degrade9 environment. These problems are associated ... -
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 ... -
The management of free-ranging lions on enclosed protected areas.
(2007)This Research investigates the potential impacts that free-ranging lions have within a small (<100 000 hectare), enclosed protected area, and it also investigates the subsequent challenges to the managers of areas such ... -
Management of fusarium wilt diseases using non-pathogenic Fusarium oxysporum, and silicon and Trichoderma harzianum (ECO-T®)
(2008)In the genus Fusarium are many important plant pathogens. The diversity of hosts the genus attacks, the number of pathogenic taxa and the range of habitats in which they cause disease are the greatest in plant pathology. ... -
The management practices of dairy cattle and their contribution to livelihoods in Matatiele, Eastern Cape.
(2016)The deepening economic crisis of many African countries has highlighted the importance of agricultural development as a basic condition for expanding rural incomes. A number of factors limit the contribution of livestock ... -
Managing relationships, learning and demands in protected areas : a social systems analysis.
(2007)This thesis seeks to contribute to the improved understanding of social systems analysis in management effectiveness research on protected areas. It develops and applies propositions for incorporating the analysis of social ... -
Manipulating morphological traits of cassava to enhance host plant resistance and biological control of cassava green mite in Zambia.
(2013)Understanding direct and indirect defense mechanisms that enhance host plant resistance (HPR) and biological control is critical for successful development of an integrated pest management (IPM) approach. Cassava green ... -
