Tissue culture techniques were applied to study the regeneration and growth of bulblets from bulb scale segments ofCrinum macowanii Bak. (bush- or march lily)in vitro. Shoots were induced on twin scales taken from the basal plate region of flowering-size bulbs on Murashige and Skoog (MS)-medium containing 0–20 mg l−1 NAA and BA and a modified MS medium (MMS(More)
In vitro bulblet formation and subsequent transplanting of bulblets to soil were studied in order to develop a cost-effective method for the mass production of three Lachenalia varieties. Clumps of adventitious shoots regenerated from leaf explants were used. Bulblet formation was initiated after 2 weeks when shoots were subjected to low temperature (4–15(More)
Amaryllis belladonna L. plants were multiplied successfully by means of tissue culture techniques. Different plant parts were tested as explant material, but plantlets could only be generated from the twin-scales and immature scapes. These in vitro-formed plantlets were divided into four parts and used for further multiplication. The twin-scale explants had(More)
The genus Zantedeschia, commonly known as the arum or calla lily, is native to Africa. Apart from the more commonly known white Zantedeschia aethiopica there are six other Zantedeschia species in South Africa with flower colours ranging from pink, cream and yellow to maroon. As cut flowers they are very popular all over the world and a multitude of(More)
Adventitious shoots and plantlets were regenerated in vitro from floral stem explants of Crinum macowanii (Bak.) (bush lily). The length (age) of the floral stem as well as the orientation and position of the explant disc in the floral stem were the most important factors affecting shoot regeneration. The highest number of shoots were regenerated when(More)
The Human Tissue Act 65 of 1983 regulates all aspects regarding organ transplants. This Act was last amended in 1989. Since then medical science has developed tremendously and to such an extent that organ transplants today are almost routine operations in many hospitals. Unfortunately the current methods of procuring human organs are not supplying the(More)
Law, religion and organ transplants Currently any organ donation in South Africa, whether from a living or a dead donor, is donated altruistically, which means that it is the free choice of the donor or the family of the deceased to donate organs. There is no financial compensation for the donor. Nearly all religions support altruistic organ donations as it(More)
In 2010 illegal kidney transplants performed in South African hospitals were exposed. Living donors (actually sellers) from Brazil and Romania were flown into South Africa where a kidney was harvested from each and transplanted into Israeli patients. The media reports that followed indicated an outcry against the sale of human kidneys. But by analysing the(More)
Phenotypic variation, SDS-PAGE and protein-DNA binding were used to determine variation during the in vitro phase of potato plantlets derived from callus and cell suspensions. Of the 27 plantlets assessed. 3 displayed a low or abnormal growth, 16 normal growth which correlated well with the original explant and 9 showed strong or vigorous growth.(More)
