Abstract
SummaryVarious hand and chemical thinning treatments were applied to Spartan trees on either M.9 or MM.106 rootstocks. Reducing the number of flowers on a tree increased the proportion of flowers that subsequently set fruit, this relationship being statistically highly significant. Both 500 mgl−1 ethephon, applied at the balloon stage of flowering, and 2100 mgl−1 carbaryl, applied when the average fruitlet diameter was either 10 or 14 mm, reduced the number of fruits carried by each tree, thereby improving fruit size and enhancing return bloom. These results indicate that chemical thinning of blossom may be an effective strategy for thinning Spartan trees.
