Résumé

Since low temperature (lower than 5 deg C) reduces sprouting, a long-term solution is the breeding of new cultivars that do not convert starch to sugar at low temperatures. However, this solution is not available yet and alternatives to the current methods are also being considered. The alternative methods can be classified into the following categories: radioactive irradiation, ozone, controlled atmosphere (O2 and CO2), camptothecin, nonanol and higher alcohols, dimethylnaphtalenes (DMN) and volatile monoterpenes (cineole and carvone). In addition, there are several other natural and synthetic compounds which will be mentioned but not discussed in detail partly because insufficient published data are available, e.g. aromatic aldehydes and alcohols, jasmonates, PSS25 and KRS-92. It is encouraging that most of the research is focussing on new sprout suppressants which are either naturally occurring or are new synthetic chemicals which are more effective at lower concentrations, compared with the currently approved chemicals. However, even though some have received very positive evaluations and others have received approval in one country, none are in extensive commercial use.
