Abstract
Small fruit size reduces fresh-market value and potential net income in sweet cherry. Several new rootstock cultivars for sweet cherry induce greater precocity, heavier blossom density, and a range of dwarfing but also may reduce fruit size. A field study was undertaken with sixth leaf `Hedelfingen' scions grown on Prunus avium L. `Mazzard' seedling rootstock or on one of 4 new rootstock cultivars: `Damil,' `Gi 148/1,' `Gi 172/9,' and `Gi 196/4.' Factorial treatments included (+/-) trickle irrigation when soil tensiometer readings reached 20 k Pa and (+/-) hand thinning to single fruits/cluster aat 7 days after full bloom. High natural precipitation reduced irrigation effect but fruit size was increased significantly by thinning. Yield differences were also seen between rootstock cultivars.
