MICROPROPAGATED CHERRY ROOTSTOCK ‘GISELA^® 5′ GROWTH CONTROL AFTER GREENHOUSE ACCLIMATION

Micropropagated cherry rootstock ‘Gisela^® 5’ plantlets of different age (from 5 to 50 days after acclimation), grown in 60 cells multipot were chosen and different nutrient foliar sprays were applied for a period of 4 months to increase diametrical growth and height of the shoot.
Results showed a rapid growth of the plants, particularly in the first month and mostly due to the growing medium and the environmental conditions.
The younger plants were able to recover the gap reaching a similar final height of the older ones but with the foliar application of PKMg the final collar calibre was slightly less than control.
On the average, the collar calibre did not evidence big differences among treatments or plant age but a clear increase was evident in comparison with not-on-trial plants normally cultivated with the nursery system.
