This account presents information on all aspects of the biology of Ceratonia siliqua L. (Carob) that are relevant to understanding its ecological characteristics and behaviour. The main topics are presented within the standard framework of the International Biological Flora: distribution, habitat, communities, responses to biotic factors, responses to environment, structure and physiology, phenology, floral and seed characters, herbivores and disease, history and conservation. Ceratonia siliqua is a lowland evergreen shrub or tree, native around the Mediterranean basin and widely cultivated in areas with a warm temperate and subtropical climate, with more than 100 named cultivars. Carob grows on a wide range of soils including nutrient‐poor and strongly calcareous, dry soils. Carob is dioecious or rarely hermaphrodite although females dominate in cultivation due to their fruit. Pollination is primarily by insects and the relatively large seeds are spread mainly by ingestion of fruits by mammals. Seed dormancy is imposed by a hard seed coat and seeds germinate readily after natural or artificial scarification. Drought tolerance is very high, acting as a drought avoiding water spender. Carob is also very tolerant of saline conditions and tolerant of fire and can act to restrict wildfire spread by generating fuel discontinuity. It shows high post‐fire regrowth. Old individuals house a diversity of associated fauna and are comparatively unaffected by serious pests and diseases. Carob has a long cultural history around the Mediterranean as a food source for humans and domesticated animals, in herbal and modern medicine and, more recently, for the carob bean gum used in a variety of domestic products and foods. Commercial production of fruits has declined over past decades but the low cultural care needed in growing orchards, potential new markets for fruit and seeds, and growing use of the tree to prevent soil erosion and sequester carbon gives carob a brighter future.

“…Many previous works correlate the morphological features of plants with their evolutionary steps. Several studies (e.g., Beerling & Kelly, 1996;Willson et al, 2008;Brodribb & Field, 2010;El Kholy et al, 2023;Ibrahim et al, 2023). Alcea have correlated the development of the epidermis, cuticle, stomatal type, and density with the type of venation and the number of lateral veins as ways of succession in the adaptation…”

Leaf Variations within Representative Genera of Tribe Malveae and their Significance in the Taxa Phylogeny

2023

L EAF macro-and micro-characters of seven genera represented by twenty species belonging to tribe Malveae, family Malvaceae were examined, measured and investigated in this study. The obtained results indicated that the petiole length, leaf blade shape, base and apex varied between the studied taxa. Meanwhile the leaf margin, number and depth of teeth/ cm in the leaf margin, type of venation and number of lateral veins can be of diagnostic value within the species. Epidermal cell characters are mostly invariable, while the type and density of hairs and presence of cavitated hairs beside the type of stomata and shape of guard cells gave valuable characters within the taxa. The results have been subjected to clustering analyses using PAST program and the resulted dendrogram shows great similarity between the taxa with the separation of both Malva aegyptia and Althaea ludwigii each in a separate clade. Diagnostic key has been instructed and the phylogenetic thinking has been postulated.

“…The higher interest of farmers in using local varieties needed an initial effort in the development of local maize varieties by identifying the characteristics and relationships between accessions through the seed morphology approach of several regions. Several researchers have reported the approach of seed morphology characteristics to obtain their relationships (Mobarak et al, 2017;El-Kholy et al, 2023;Alridiwirsah et al, 2023). Likewise, the morphological diversity of local maize plants has been reported in Ivory Coast (N'da et al 2014), Nigeria (Salami et al, 2007), Benin (Salami et al, 2015), and molecularly in Kupang, Indonesia (Uslan & Jannah, 2020).…”

The Cluster of Local Maize Accessions Based on Seed Characteristics from North Sumatra

et al. 2023

T HE use of local maize is still in high demand by farmers in Indonesia. The development of local maize needs to be discovered through a morphological approach. This study was to obtain seed characteristics and similarities of local maize from North Sumatra. Local maize accession seeds were taken by four districts/cities (Binjai, Serdang Bedagai, Deli Serdang, and Mandailing Natal) from North Sumatra, Indonesia from July to September 2022. A hybrid variety of maize was selected for comparison. Seed characteristics were measured in each accession with four replications. A descriptive-analytic method was selected in this study and data were analyzed using one-way ANOVA and followed by Tukey at P<0.05. Correlation analysis, similarity matrix, hierarchical cluster, and constellation plot were constructed in this study. The results showed that SB-1; DS-3; SB-4; and SB-2 accessions had higher seed characteristics than other accessions. The SB-5 accession had the nearest neighbors (0.743) and two accessions (BI-1; DS-2) were classified into one cluster with a hybrid variety. This finding indicates that several local maize accessions are nearest to the hybrid characteristics. A novelty of this study informed that local maize had an opportunity to be used in the fields.
