| Résumé: | The study was undertaken to determine the influence of pollen sources on fruit set, yield and fruit
quality of date palm (Phoenix dactylifera L.) cv. ‘Mejhoul’. Six different male trees (symbolized
from M1 to M6) and six ‘Mejhoul’ female trees were selected for experiment, on female tree, six
spathes were selected, each spathe were pollinated by one pollen grains source. The results indicated
that pollen source significantly affected all parameters measured, the maximum fruit set percentage
was obtained for spathes pollinated by M1 (67.90%), however, this percentage were minimal for
spathes pollinated by M4 (30.22%). As for the yield, the M1 pollinizer engendered a net yield
enhancing of 36.50% compared to the average yield (42.52 kg/palm). Pomological characteristic of
the fruit like fruit weight, flesh weight, fruit length, fruit width and flesh/ seed ratio were
significantly improved with pollination from M5 compared to other male trees. The obtained values
of dietary mineral matter ranged from 1.64 to 2.03% for dates from M2 and M5 pollinizers
respectively. Total individual sugars content of the dates varied from a minimum of 70.80 g/100 g
dry matter obtained for dates from M4 to a maximum of 84.81 g/100 g dry matter recorded for the
dates from M6. The results suggested that best pollen source (male palm) should be selected for
‘Mejhoul’ dates to get most desired characteristics |
