This study was conducted in the spring of 1999 in Al-Souida Region of
Syria, to know the effect of flower pollination by honeybees on flower and fruitset
and on the crop productivity of three varieties of apple. The experiment was
repeated in the
spring of 2001 on the same varieties in addition to others like
Yellow sport, but the weather conditions (spring-frost) didn’t allow to obtain
results.
This study was conducted in the spring of 2001 in the apiary field at Faculty
of Agriculture, Damascus University - Syria, for the purpose of studying the
effect of flower pollination by honeybees on fruit-set and consequently on the
crop producti
vity of two varieties of squash, named : Berneel and Mabrukeh .
The rate of set fruits resulting from the visits of honeybees was calculated
and compared with the control, which was isolated to prevent bees reaching it.
The result in Berneel variety was 93.84% of setting flowers in the
experiment against 9.91% in the control. The results were in Mabrukeh variety
94.07% in the experiment, against 14.79% in the control.
The study has assured the importance of the density of bees in squash fields.
When the average of visits of honeybees to each flower was 7 visits per hour,
the flower-set rate was 100%. However, when the average of visits of honeybees
has declined to only 2 visits per flower per hour, the rate of set has also declined
to 60%.
The research trial was carried out at University of California, Davis,
Agriculture and Natural Resources, Cooperative Extension–Kearney
Agricultural Center (KAC).
Part of the scientific work in the laboratory started from November 1, 2001
through
out the end of February 2002. This trial was conducted using Pistacia
vera; the female variety ‘Kerman’ and its pollinator, variety ‘Peters’;… both
are grafted on the rootstock UCB1.
