Abstract

The effects of the synthetic cytokinin CPPU on the fruit size and yield of Spadona pears were examined in Israel during four consecutive years.
CPPU caused appreciable increases in fruit size, when applied at 10-20 ppm, two weeks after full bloom, whereas application four weeks after full bloom gave only small effects or none.
CPPU increased fruit size with no influence on fruit number, fruit shape and seed number, and it did not reduce the return bloom in the following spring.
A semi-commercial applications of 10 ppm CPPU increased fruit size by 40% in 1999 and 100% in 2000 with an increase of about 50% (1999) and 30% (2000) in the total yield.
Our findings demonstrate the effectiveness of CPPU application in Spadona pear and show that it has a significant potential to improve cropping, without any negative aspects.
