This research was conducated on Ceratonia siliqua L. in vitro to study the effect of
some growth regulators in both multiplication and rooting stage. And determine the best
concentrations wich lead the highest rate of multiplication (interms of number of shoots
and length), and the best rooting (interms of percentage of rooting, number of roots and
length).
The study showed that We can Processing of a new pleasant nourishing drink from
carob seeds, by roasting the fresh seeds of Carob at 200C° for 2 min .
The results of sensory tests and test taste according to international quality
standards ISO8588
7: 2005 at samples drink prepared from seeds roasted at different
temperatures and times showed that the sample prepared at 200C° for 2min is the best, also
the results of chemical analysis for powder of roasting carob seeds at 200C° for 2 min that
used in prepare the drink showed that it has a high nutritional value because of its high
content of protein 19.8% and fiber 12.9%, low content of fat to 1.6% and sugar to 1.5%,
and completely free of caffeine, therefore, it suitable as a healthy and nourishing drink for
patients with heart and diabetes disease. The manufacture of this drink is economically
This study aimed to obtain seedlings balanced and superior in growth, by searching
the effect of seed size on the growth and development of seedlings of carob tree
( Ceratonia siliqua L.) developing in containers Minirhizotron in the growth room in
Research Center in Bouka-Lattakia. Seeds were divided into three categories (large-size
LS, control CS, small-sized SS) and studied several quantities indicators of growth and
development of the total shoot and root of the seedlings for a period of three months.
For a radical system, results indicated a high significant superiority in the large
seeds values for the main root of the overall growth rate such as length (cm) and the speed
of growth (cm/3days) and secondary roots (total number, total length/cm) height to control
and small seeds. And the significant superiority of the seeds of the control on the small
seeds.
It has also given large seeds higher values regarding all indicators related to the shoot
system such as average diameter and average height and average number of phalanges
stem and leaves, and ending with the dry weight of shoots.
Results for the study of periodic growth curves for the main root and main stem of
the three treatments indicated the presence of a great similarity in the overall appearance of
these curves, which refers that the appearance is not affected by this change in the amount
of seed size. On the other hand, the phenomenon was observed in contrast growth
Antagonism clearly between the totals shoot and root with any end to the growth of main
root accompanied by a junior at the end of the main stem growth and vice versa.
This research was carried out during 2014 - 2015 in Scientific Centre for Agricultural
Researches. This research aims to determine the effect of some biological and genetic
indicators on the success of Carob seedlings in nurseries by studying three
kinds of
grafting: Auto-grafting, Homo-grafting and Hetero-grafting. Rootstock aged one year and
resulted by two chosen genetic types, namely, SnobarJablah and Alhafa were used. Scions,
they were taken either from seedlings with age of one year resulted by these two types or
from branches aged one year from the selected two types as well. Grafting was conducted
by using Whip Graft way in spring.
Auto-grafting has indicated the importance and the role of biological and genetic
factors for grafts and their impact on rates of grafting success. Concerning rates of success,
the results have shown that Auto-grafting surpassed Hetero-grafting with a significant
reference for both of two genetic types, regardless if the used scion was young or old.
In addition, Auto-grafting has shown surpass on other kinds of grafting, in terms of
subsequent growth of scions. On the other hand, a variety in biological indicators values
has been noticed between the two genetic studied types. In favour of SnobarJablahtype
againstAlhafaʼs type. However, the differences of values were not significant for the most
of conducted measures.
As for the age of scions, the results have pointed out that values of Hetero-grafting
with young scions surpassed values of Hetero-grafting with old scions in terms of the rate
of grafting success and values of biological studied indicators.
