Abstract

Abscission of flowers inSolatium tuberosum L. cv Katahdin immediately after pollination and probably before fertilization was a barrier to crossing betweenS. tuberosum andS. chacoense Bitt. in our greenhouse. A new method for improving flower retention was evaluated. Treatment of flower buds at an early stage with silver thiosulphate (STS) was compared to the cut stem technique. Flower retention on STS-treated Katahdin was greater than on untreated plants, and better than that on cut stems. Advantages of STS over the cut stem method include ease of application and reduced maintenance requirements of the plant material.
