Abstract
An experiment was carried out to determine planting densities for Y-shaped peach trees in greenhouses.
In February 1989, ‘Flordaprince’ micropropagated trees, no more than 30 cm high and 3 mm in stem diameter were planted in a polythene greenhouse.
To establish a planting density of 3000, 4000 and 5000 trees/ha, the trees were placed 4.9 m between the rows and 70, 52 and 42 cm, respectively, along the row.
In 1991, soon after harvesting, tree density in two rows was reduced by cutting back and uprooting one out of two trees, so that three more densities (1500, 2000 and 2500 trees/ha) were attained.
Data collected in 1991 and 1992 were the following: trunk diameter, flower density, fruit set, yield, fruit size, LAI, dry matter partition.
Results showed that planting densities higher than 4000 trees/ha did not increase yield per ha while average fruit weight was adversely affected starting from 1500 trees/ha.
