Abstract
3.4. SUM MAR Y
This experiment was conducted for each of the two
selected (Acacia saligna and Acacia farnesiana) for this
study after applying the boiling water as a pregermination
treatment. Seeds were germination in trays filled with
proper media (1:1 peat: sand) on February 1st, after 15-
days from seeding. Seedlings were ready to be transplanted
into a large pots of 25 cm diameter filled with peat : sand
(1:1) media.
Performance of acacia seedlings was monitored after
applying the following factors in a split plot design.
Irrigation with the previously mentioned saline water at 5,
10, and 15 days intervals (main plots). Irrigation was
applied at a rate of 350 ml/pot at each irrigation time.
Three replications were used in which the experimental unit
was 4 pots with one seedling in each pot.
Results could be summarized as follows:
1. Height of Seedlings:
Over all of the applied treataents, the highest of
acacia seedlings did not increased auch froa the first to
the second growing aonth (13.6 vrs 17.3 ca). However, the
height of seedlings was drastically increased froa the
second to the third month (17.3 vrs 44.1 ca).
Acacia farnesiana did not tolerate with the applied
salinity of the water for irrigation since all of the
treated seedlings died during the second grOWing .onth
except the control plants.
The survival could be affected by the salinity level of
the water for irrication and the specie as well. Neither the
salinity level nor the irriaation intervals showed any
- 112 -
significant effect on the height of Acacia farnesiana
seedlings during the first growing month.
2. Dry Hatter Content:
Irrigation with water of any of the applied salinity
levels caused a significant reduction in the dry matter
content of the grown seedlings at the end of the first
grOWing month compared with the control. Moreover, the
difference in salinity levels of the water did not exhibit
significant difference in the dry .atter content of Acacia
sali#na seedlings at the end of the second and the third
grOWing months.
The less frequent irrigation with saline water C15
days) was bad enough as the aore frequent irrigation (5
days) in its effect on the dry matter content of the grown
seedlings.
3. Root/Shoot Ratio:
The different
water did not show
