“…On the other hand, there are no correlations among characteristics describing the pods and those describing the seeds except for pod weight. In agreement with our results, many authors have underlined that significant correlations, which were found among characteristics describing pod (El Kahkahi et al, 2014;Elfazazi et al, 2017;Srečec et al, 2016).…”

“…Forty seven Moroccan carob populations from different sites were studied to assess their genetic variation based on pods and kernels measures. Most of the pa-rameters measured showed a significant difference that indicates a high genetic diversity (El Kahkahi et al, 2014;Elfazazi, Jbilou, Assaidi, Benbati, & Harrak, 2017).…”

Carob tree Ceratonia siliqua L., is an evergreen endemic species found naturally in El-Jabal El-Akhdar region which is located immediately south of the coastal belt in the northeastern region of Libya. Morphological characteristics have been the main descriptive tool to characterize a given collection or germplasm, or to identify and differentiate wild type populations. Eighteen carob population were collected from six different sites in El-Jabal El-Akhdar area. Seven characters on discriminative pods were measured: the length, width, thickness, number of seeds, weight of pulp, and yield as well as one character to seeds: the weight seeds. The present study showed that the choice of pod characters to assess Libyan carob diversity is a useful and powerful tool. The means and standard deviations of morphometric characters measured in Libyan carob showed highly significant differences among the studied populations for all the examined characteristics. Differences in morphometric traits of carob pods and seeds among Libyan carob populations are primarily caused by genetic factors. The pod size of Libyan carob is considered to be the medium size (10.89 – 17.55cm).

“…These results are in agreement with those obtained by Makrem et al [12] in Tunisia and by Barracosa et al [2] in Portugal. The results concerning the seeds of the northern region of Morocco are similar to those reported in Fez (Morocco) by Elfazazi et al [13]. On the other hand, cultivation practices of carob seem to improve the mass of the pod, the stem length, the mass of the pulp, the length of the seed and the apical and basal width of the pod.…”

“…The study carried out by Boublenza et al, [38] In 2019 showed significant variability between the 10 varieties of Algerian carob, length, width, pod thickness, number of seeds and pod weight are respectively between 13.13 and 18.75cm, 1.81 and 3.10cm, 0.61 and 0.80cm and between 6.79 and 13.23 and between 7.04 and 30.57g. In Morocco, the studies completed on the agro-morphological characterization of the Moroccan carob tree show significant phenotypic diversity [35,36]. In Beni Mellal (middle atlas), the carob tree population is characterized by a length of 12 and 15cm, width 1.5 and 2.5cm, pod thickness 0.4 and 1.37cm, number of seeds 10.67 and 12.5 [36].…”

In order to improve the germination rate of carob seeds (Ceratonia siliqua L.), we studied the morphological characteristics of the fruits (pod and seeds, integumentary hardness and tolerance to abiotic stress of the seeds) of seven ecotypes of carob trees from four regions of Morocco. The fruits of its seven populations were studied according to seven discriminative characteristics relating to the pods (length, width, thickness, total number of seeds, total weight of the pulp, seeds per pod and yield of pods per tree) and four discriminative characteristics relating to the seeds namely length, width, thickness and total fresh weight of seeds. Integumentary hardness was evaluated by pretreating the seeds with boiling water and 95% sulfuric acid. Similarly, we also followed the evolution of water absorption by the seeds during 4 days and we evaluated on these seeds pre-treated, effects of different incubation temperatures (10°C, 25°C and 40°C), their tolerance to different concentrations of NaCl, PEG6000 (0MPa, -0.5MPa, -1MPa and -1.5MPa ) and their reversibility. The morphological characterization of the fruits allowed us to group the populations studied into three groups. Soaking the carob seeds in sulfuric acid for 20 minutes improved the germination rate and time. The evolution of water absorption makes it possible to distinguish two phases. The first phase is obtained during the first 24 hours and characterized by a rapid penetration of water, and second phase which lasts over the last 72 hours and which is characterized by a slow entry of water. The optimum temperature for germination of seeds from all provenances is 25°C. The germination behavior of carob under conditions of osmotic stress demonstrated a highly significant treatment effect (concentration of PEG6000) on the rate and mean time of germination and revealed that this species is very resistant to drought. This study also showed that, salt has a depressive effect on the average germination rate, time and length of radicles. The results of the reversibility test showed that the germination of seeds transferred from osmotic stress and salt stress (-0.5, -1 and -1.5MPa) and from the temperature of 40°C. is totally inhibited. On the other hand, seeds transferred from a temperature of 15°C resume germination under optimal conditions. This study allowed us to select a variety with high yield and tolerant to various biotic constraints.
