Table(5) shows significant effects of cutting
stage on the percentage of wilting flowers as the
highest value of the wilting flowers (76.63%)
was obtained when the flowers were taken at the
non opening sepals stage, followed by treatment
of picking flowers at the stage of full opening
petals (71.53 %), and then gradually decreased
to reach the lowest per cent (33.33%) when the
flowers picked in the semi opening sepals stage.
No significant differences were recorded for
the effect of how to pick the flowers. The
highest average percentage of wilting flowers
was recorded when flowers picked and then
06
placed in water after 10 minutes (51.66%), on
the other hand, the lowest average percentage of
wilting flowers was recorded when the flowers
picked under water directly (39.16%). The
results of interaction affect showed that the
highest average percentage of wilting flowers
(100%) was obtained when the flowers picked
and then placed in water after 10 minutes in full
opening petals stage, whereas the lowest average
percentage of wilting flowers was obtained when
the flowers picked and then placed in water
directly (6.25%) in non opening sepals stage.

Means followed by the same letters within each factor or interaction don't differ significantly
(p≥ 0.05) according to Duncan's multiple .
Table (6) shows no significant differences in
the average percentage of dry material. The
highest percentage of dry material was recorded
when flowers were picked at the stage of full
opening petals, as compared with picking semi
opening petals stage (21.91%). The largest
percentage of dry material (31.25%) was
recorded when the flowers were picked under
water directly then decreased to reach the lowest
values (21.87%, 22.07%) when the flowers
picked and then placed in water directly and in
water after 10 minutes respectively.
Flowers picking under water led to increase
the proportion of dry material in flowers, which
reached the highest percentages (35.40%,
31.57%) when they were picked under water
directly at the stages of full opening petals and
semi opening. This value was decreased to reach
the lowest (16.64%) when flowers were picked
and then placed in water after 10 minutes in semi
opening petals stage.
