Lecture given by Prof G Pietersen at a Winetech/VinPro information day.
Nurserymen, grape producers and winemakers have a joint responsibility to ensure that wine of the highest quality is possible and indeed made. Poor callus development, nursery performance and affinity of scions and rootstocks annually result in huge financial losses for both nurserymen and grape producers. The factors leading to poor performance of graft combinations during callusing and in nurseries and vineyards are not well known and are often ascribed as being of morphological, physiological and/or environmental origin. The quality of graft material can be defined as the ability for callusing, root formation, budding and growth during both the callusing period and in the nursery. Research was done to improve callus formation and affinity/growth of graft combinations and to contribute to the improvement of the cultivation of stocks to be delivered to the grape producer. A document is compiled that presents the research results obtained by ARC Infruitec-Nietvoorbij in collaboration with several role players from the SA Wine Industry over a 10 year period. In addition, some general information on important physiological and morphological aspects of plant material is included.
A detailed overview document concerning grapevine leafroll has been compiled by Mrs. Roleen Carstens of the ARC Infruitec-Nietvoorbij. This document was requested and funded by Winetech and is a must for every grower to read.
