Thesis 2009
I. Establishment stage:
Sterilization treatments had a non significant effect on survival% of
Paulownia explants. However
- the combined treatment with mercuric
chloride + clorox gave the highest survival%
- while clorox achieved the
lowest value.
A spontaneous rooting occurred in the establishment stage on
Paulownia explants. The effect of explant type was significant on shoot
length
- fresh weight of shoots - number of roots and root length of
Paulownia. Values of these characters were significantly higher when
explants were excised with a piece of callus
- compared to those without
callus. The effect was insignificant concerning the total number of shoots
and total number of leaves.
A significant effect was exerted by MS strength on shoot length
- total
number of leaves
- number of roots and root length. The highest values of
these parameters were achieved on the normal strength of MS medium.
Values of total number of leaves produced on ½MS and 1½MS besides
number of roots on 1½MS are significantly among the highest ones.
Values of the above-mentioned four characters declined significantly to
the lowest category when explants were inoculated on MS medium at
double strength (2MS). The effect of MS strength on Paulownia explants
was insignificant concerning the total number of shoots and fresh weight
of shoots.
The interaction between explant type and MS strength had a significant
effect. When explants with a piece of callus were inoculated on MS
medium
- root length was the highest - or on 1½MS medium - both number
of roots and root length were significantly the highest
- . Insignificant
effects were exerted by this interaction on total number of shoots
- total
number of leaves
- shoot length and fresh weight of shoots
