PollenAid Trials

Pollinating flowers by spraying pollen with PollenAid® is a commercial success story.

The PollenAid® process maintains the viability of kiwifruit pollen in a water-based suspension so it can be sprayed on to female flowers to set seeds. The more seeds that set, the bigger the fruit will be.

By using PollenAid®, flowers can be pollinated during adverse weather, when insect and wind pollination is not possible.

In replicated trials conducted in No. 4 Road, Te Puke, New Zealand, vines were either pollinated by wind and bees or a combination of wind, bees and the PollenAid® process using the Kiwi Pollen Sprayer. To simulate the effect of wet weather, all male flowers in the treated area were removed prior to flowering. The trial was conducted by an independent consultant and the crop was graded by HortResearch's manager; the late Bruce Stowell.
