  In this study, variability in eight pod traits of 300 genotypes (mother-tree) of A. tortilis ssp. raddiana (Savi) Brenan collected from southern regions of Morocco was assessed. In the analysis of variance, we found that Acacia raddiana have significant differences in all traits due to genotype within provenances, but only in pod length, seed weight per pod, seed number per pod, infected seed number per pod and 100-seed weight due to provenances. In general phenotypic coefficient of variation was higher than the genotypic coefficient of variation, indicating the predominant role of environment. High heritability and genotypic gain were recorded for 100-seed weight (92.75 and 17.20%), empty pod weight (53.68 and 21.18%) and pod weight (46.45 and 16.13%), respectively, indicating the additive gene action. Seed weight had positive correlation with seed length, pod weight, seed weight per pod and empty pod weight. On the basis of the Principal Component Analysis (PCA) and the hierarchical cluster analysis, respectively, tow clusters were obtained with highest number of provenances falling under cluster I. The first cluster is composed of the provenances: Agdz, N’koub, Tazarine, Mceissi, Tata and Tissint, the second cluster presented by the provenances: Foum Zguid, Gluemim, Mseid and Assa. Among the clusters formed cluster 1 presents the best means for the majority of traits studied.

  Recently, a large plantation has been established in Morocco, to reduce water and wind erosion, rangeland degradation, sand movement and to enhance the restoration of the vegetation cover. However, this plant material has unknown genetic characterization. In addition, several local classifications and morphological descriptions were used. The objective of this study was to analyze the genetic diversity using RAPD markers in a collection of 13 provenances of Moroccan Opuntia ficus indica (L.). Based on 13 random primers, the result showed that the level of diversity (h) and polymorphism varied according to the provenance. A high genetic differentiation was found between the provenances (Gst = 0.29), thus some loci were characteristic of certain provenances. These results can be used to characterize genetic resources of Morocco cactus pear and to initiate a program of genetic improvement and selection.

  Back Ground and Objective: Medicinal plants are getting popular day by day because of their easy accessibility and reasonable costs. This study investigated the chemical composition and antifungal activity of Lavandula mairei, Lavandula dentata and Tetraclinis articulata plants essential oils against Penicillium digitatum, Penicillium italicum and Geotrichum citri-aurantii, the main post-harvest pathogens in citrus. Materials and Methods: Essential oils were obtained by hydrodistillation from areal parts of tested plants. Afterwards, they were analyzed by means of GC-MS and their antifungal efficacy was tested in vitro by using the agar plate’s method. Results: The main constituents were carvacrol for L. mairei, camphor, linalool and β-pinene for L. dentata and bornyl acetate, α-pinene, borneol and limonene for T. articulata. In the in vitro assay, the effect of essential oils on mycelial growth and spore germination varied significantly between tested plant species. Complete growth inhibition of the three pathogens was obtained by L. mairei essential oil. Also, L. mairei displayed the highest bioactivity, inhibiting completely the spore germination of the three pathogens. Moreover, this species showed fungistatic and fungicidal activity on the three fungal pathogens. Conclusion: In this study, L. mairei essential oil showed great antifungal activity which could represent a potential alternative to synthetic fungicides for the control of citrus fruit fungal pathogens.

  Background and Objective: Many soil rhizospheric bacteria can transform insoluble forms of phosphorus and potassium to an accessible soluble form, contributing to plant nutrition as Plant Growth-Promoting Rhizobacteria (PGPR). The main purpose of this study was to isolate and identify the native population of phosphate and potassium solubilizing bacteria in the rhizospheres of date palm (Phoenix dactylifera L.) grown in the Al-Qassim region, Saudi Arabia. Materials and Methods: The rhizobacterial strains were isolated and in vitro screened for their phosphate and potassium solubilizing potential and ammonia production by using routine plate assay methods. The selected strains were identified based on nucleotide sequence data from the 16S ribosomal rRNA encoding gene. Results: The strains PSA1 and AZA2 have exhibited the highest qualitative efficiency of phosphate solubilization, while the strains AZA2 and PSA2 showed the most pronounced ability to solubilize potassium. The strains S1-3, I2 and AZS2 were the most effective for the production of ammonia. Based on the rRNA sequencing, these strains were identified as Enterobacter ludwigii (PSA1, PSA2 and AZA2), Bacillus subtilis (AZS2), Bacillus cereus (I2) and Klebsiella oxytoca (S1-3). Conclusion: These results suggest that some indigenous rhizobacterial strains could be an efficient and eco-friendly alternative to chemical fertilizers in the process of bio-fertilization of date palm.
