Foliar application of ethephon induces bud dormancy and affects gene expression of dormancy- and flowering-related genes in ‘Mauritius’ litchi (Litchi chinensis Sonn.)

Autor: Regina B. Cronje, Elliosha Hajari, Arnold Jonker, Innocent M. Ratlapane, Xuming Huang, Karen I. Theron, Eleanora W. Hoffman

Publikováno v: Journal of Plant Physiology. 276:153768

A previous study showed that foliar application of ethephon to litchi trees with mature shoots and dormant terminal buds during autumn successfully inhibited new vegetative shoot growth prior to floral induction thereby promoting carbohydrate accumul

Peel water vapour permeance of Japanese plums as indicator of susceptibility to postharvest shriveling

Autor: Karen I. Theron, Imke Kritzinger, E. Lötze, Gustav F.A. Lötze

Publikováno v: Scientia Horticulturae. 242:188-194

Moisture loss and postharvest shrivelling of some Japanese plum cultivars result in significant financial losses in the South African stone fruit industry. Even though fruit are stored at optimal temperatures and packaging solutions are implemented t

SUMMARY Brandies of male and female plants of the dioecious Leucadendron rubrum Burm. f. were collected on the site of the Weikamp weather-station in the Jonkershoek State Forest, Stellenbosch, from July 1990 to September 1991. Xylem sap was extracte

Influence of pollination on seed content and mealiness development in ‘Forelle’ pear as detected with X-ray micro- and nano-computed tomography (CT)

Autor: Letitia Schoeman, T. Human, E. M. Crouch, Willem J. Steyn, W. J. Fourie, R. J. Cronje, Karen I. Theron

Publikováno v: Acta Horticulturae. :371-378

'Forelle' pear fruit is prone to mealiness. The aim of this study was to establish whether pollination and seed development influence the mealiness and tissue structure by characterising microstructural differences using X-ray computed tomography (CT

Mealiness in ‘Forelle’ pears: relationship between TSS and prediction based on FT-NIR spectroscopy

Autor: E. M. Crouch, L. Schoeman, Tavagwisa Muziri, Helene Nieuwoudt, Karen I. Theron

Publikováno v: Acta Horticulturae. :339-346

'Forelle' pears are prone to mealiness, a dry textural disorder characterised by loss of free juice and development of a floury texture when fruit softens. There is currently no method of determining mealiness in intact fruit and no instrumental inde

Impact of Temperature on Autumn- and Spring-initiated Inflorescence Systems within a Biennial Pruning System of Protea ‘Pink Ice’ Cut Flowers

Autor: Eugenie-Lien Louw, Karen I. Theron, S.J.E. Midgley, E. W. Hoffman

Publikováno v: HortScience. 53:295-303

The potential impact of increasing temperatures driven by climate change on cultivated Protea cut flower production systems is not known. This study used a biennial pruning system in Protea ‘Pink Ice’ to track the physiological and reproductive r

Efficacy of ACC (1-aminocyclopropane-1-carboxylic acid) as a Chemical Thinner Alone or Combined with Mechanical Thinning for Japanese Plums (Prunus salacina)

Autor: Karen I. Theron, Human Steenkamp, Willem J. Steyn

Publikováno v: HortScience. 52:110-115

Thinning is a labor-intensive and expensive, but important practice in japanese plum production requiring new thinning strategies. The purpose of this study was to evaluate a new chemical thinner 1-aminocyclopropane-1-carboxylic acid (ACC) on ‘Laet

Microstructure analysis and detection of mealiness in ‘Forelle’ pear ( Pyrus communis L.) by means of X-ray computed tomography

Autor: E. M. Crouch, Pieter Verboven, Karen I. Theron, Bart Nicolai, Zi Wang, Tavagwisa Muziri, Dennis Cantre

Publikováno v: Postharvest Biology and Technology. 120:145-156

Mealiness causes fruit to develop a soft and dry texture during ripening. No technique currently exists to detect mealiness non-destructively. Two studies were conducted to i) determine the potential of X-ray macro computed tomography (macro-CT) to d
