Some aspects of water relations on avocado Persea americana (Mill.) tree and fruit physiology.
The effect of long-term irrigation on water relations of 'Fuerte' avocado trees, and the consequences for fruit ripening and physiology, particularly physiological disorders, were studied. Four irrigation regimes were ...
Temperature as a factor in nectarine production in the Western Cape.
Phenological and climatic data were collected from nectarine orchards containing the cultivars Sunlite, Flavortop and Fantasia, growing in six climatically divergent areas in the Western Cape, South Africa. Shoots were ...
Ovule and seed studies in relation to fruit growth in Carica papaya L. cl. honey gold.
No abstract available.
Tissue culture studies on the genus Rosa with special reference to the shoot tip.
A modified Berthelot (1934)-Knop (1865) solution was found to support the growth of rose pith segments while Murashige and Skoog's (1962) medium did not. Possibly the NH(4)+ content of the latter medium is toxic to rose ...
Optimization of flower and seed crop production in temperate eucalyptus orchards in South Africa through site selection and environmental manipulation.
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 ...
Plant hormone homeostasis and the control of 'hass' avocado fruit size.
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, ...
Induced polyploidy as a tool for the development of novel South African indigenous crops.
Polyploidy is a naturally-occurring phenomenon in plants and has been reported as an important pathway for evolution and speciation; it is estimated that a large percentage of flowering plants are polyploid in origin. ...
Post-phloem transport and metabolism of sucrose in avocado.
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 ...
Variations in growth, yield and metabolites of African ginger (Siphonochilus aethiopicus) in responses to irrigation regimes and nitrogen levels.
Medicinal plants are valuable natural resources used as traditional medicine and have economic significance. African ginger (S. aethiopicus) (Schweinf.) B.L. Burtt is one of the most important rhizomatous plants, highly-valued ...
