FLOWERING AND FRUITING OF BURLAT SWEET CHERRY ON SIZE-CONTROLLING ROOTSTOCK

The effect of rootstock on the flowering and fruiting response of swee t cherries (Prunus avium L.) was investigated using 4-year-old branch units. The cherry rootstock Edabriz (Prunus cerasus L.) affected the f lowering and fruiting response of 'Burlat' sweet cherry compared to Ma xma 14 and F12/1. Branches of trees on Edabriz had more flowers, more flowers per spur, more spurs, more fruit, higher yields, smaller fruit , and a reduced fruit set compared to the standard rootstock, F12/1. O ne-year-old branch sections had more flowers and fruit, higher fruit w eight, and heavier fruit size compared to older branch portions.
