TY - JOUR AU1 - COOMBE, B. G. AB - FRUIT set of seedless cultivars of the grape (Vitis vinifera L.) has been improved by treatment with auxins1,2, gibberellins3, and kinins4. By contrast, fruit set of seeded cultivars has not been improved by treatment with these growth regulators. For two reasons, the set of seeded and seedless grapes has been examined further: first, to examine the effect of pre-anthesis treatments—previous experiments have for the most part been confined to application at or soon after anthesis, whereas earlier treatments have been shown to increase fruit set in pears5 and apples6; secondly, to compare regulators which have been classified as auxins and gibberellins with anti-auxins and anti-gibberellins (or growth retardants); the latter group has not previously been tested on grapes.
