Fragrance addition improves visitation by honeybees and fruit quality in kiwifruit (Actinidia deliciosa).

BACKGROUND
Kiwifruit is an important horticultural crop all over the world with an important development in Argentina. This dioecious crop presents a short blooming period with nectarless flowers, and its fruit production depends on cross-pollination. Here, we tested whether kiwifruit quality increases by using honeybees exposed to female flowers treated with an artificial fragrance. The three experimental treatments were: A, sprinkled female flowers with 1:1 sugar syrup + Lavandula hybrida extract solution (a new attractant substance specially developed for this study named Lavandin Grosso); B, sprinkled female flowers with 1:1 water + sugar syrup (female flowers with additional sugar syrup reward), C (control; female flowers exposed to honeybees).


RESULTS
Results showed a higher number of visits of honeybees to the female flowers sprinkled with the attractant substance Lavandin Grosso, as well as higher fruit quality (weight, number of seeds, regularity in fruit size).


CONCLUSION
Our study demonstrates the potential of fragrance-treated flowers to improve yield production in kiwifruit. This article is protected by copyright. All rights reserved.
