Pulp weight: The pulp weight <strong>of</strong> fruit was significantly (P < 0.05%) affected
by pollination with <strong>different</strong> <strong>pollen</strong> sources in both years (Table 9). Maximum
pulp weight (17.01g) was recorded when spathes were pollinated with M 8 <strong>and</strong>
M 9 in 2007 <strong>and</strong> with M 9 in 2008 (13.88g). The cumulative <strong>effect</strong> <strong>of</strong> male x
<strong>whorl</strong>s was non-significant in 2007 <strong>and</strong> significant in 2008. However,
maximum pulp weight (18.31g) was found in W 2 M 8 interaction in 2007 <strong>and</strong>
W 2 M 3 in 2008 (15.01g). These results are similar to those <strong>of</strong> Al-Ghamdi et al.
(2), Hani et al. (7) <strong>and</strong> Iqbal et al. (13) who reported significant <strong>effect</strong> <strong>of</strong>
<strong>pollen</strong> sources on fruit pulp.

Stone weight: Maximum stone weight (1.37g) was obtained from trees
pollinated with M 6 in 2007 <strong>and</strong> with M 9 in 2008 (1.12g) (Table 10). The
cumulative <strong>effect</strong> <strong>of</strong> male x <strong>whorl</strong>s was non-significant in both years.
Maximum stone weight (1.45g) was recorded from W 2 M 2 interaction in the
year 2007 <strong>and</strong> W 2 M 9 in 2008 (1.18). These results do not agree to the
findings <strong>of</strong> Marzouk et al. (16), Hussain et al. (10) <strong>and</strong> Jalal et al. (8) who
reported significant <strong>effect</strong> <strong>of</strong> <strong>pollen</strong> sources on stone weight.
