1989

Trial was conducted in a dense planting (2,2/0 trees/hectare) of pear cv. Passe Crassane on quince MA rootstock, including pruning of differing intensity, leaving 50, 100, 150 and 200 fruit buds per tree and control (no pruning). The trial was carried out in 1985, 1986 and 1987 at the age of 7, 8 and 9 years, respectively. Data are presented on the number of fruits harvested, yields, vegetative growth increment and flower bud differentiation. There was found a positive correlation between the number of fruit buds and the number of fruits harvested (r = 0.69, d = 0,48, v = 0.323. Fruit mass was larger with more severe pruning, so that the yields in all the treatments were made uniform. A more severe pruning results in higher-quality fruits and better economic effect. Vegetative growth increment was larger with more severe pruning and the reverse. A moderate pruning, leaving 250,000-300,000 fruit buds per hectare, has been recommended.
