“…lettuce (54.1%) from the first harvest in the same conditions. In addition, it has been observed that the intensity of purple leaf colour is positively correlated in varieties rich in methyl chavicol [ 21 ]. However, in compliance with Liber et al (2011), our results show that the biosynthesis of phenylopropanoids e.g., methyl chavicol, is not characteristic exclusively for the purple morfotypes.…”

Five varieties of Ocimum basilicum L. namely lettuce, cinnamon, minimum, latifolia, and violetto were separately cultivated in field and greenhouse in the island Kefalonia (Greece). The effect of successive harvesting to the essential oil content was evaluated. In total 23 samples of essential oils (EOs) were analyzed by GC-FID and GC-MS. Ninety-six constituents, which accounted for almost 99% of the oils, were identified. Cluster analysis was performed for all of the varieties in greenhouse and field conditions, in order to investigate the possible differentiation on the chemical composition of the essential oils, obtained between harvests during growing period. Each basil variety showed a unique chemical profile, but also the essential oil composition within each variety seems to be differentiated, affected by the harvests and the cultivation site.

“…Genetic variation in plants can be estimated by such varied tools as morphological, chemical and molecular markers. While morphological variation can be highly affected by the local conditions of the collection site [11], chemical variation is a robust tool for medicinal plants caracterisation in relation to their morphological traits [12]. Furthermore, the importance of fennel as a medicinal and spice plant involved the need to improve some of its agronomical characteristics, such as early ripening, larger or smaller fruits, limited growth height, higher essential oil yield and resistance to fungal diseases [13] _ [14] _ [15].…”

Knowledge on phenotypic and chemical diversity among fennel (Foeniculum vulgare Mill.) cultivars is a milestone in the improvement of this specie which is considered as one of the most important medicinal plants. For this purpose, the present study was conducted in order to compare for the first time fennel cultivars regarding their agro-morphological traits as well as their essential oil yield and composition. Ten fennel cutivars were cultivated in a randomized completely block design whereas the seeds essential oil was analysed by GC-MS analysis. All phenotypic traits showed variation among the cultivars examined. Correlations between traits showed a significant positive relation between yield and height, number of leaves, number of branches, number of umbels , number of umbellate and peduncle length. Significant genotypic variations were also observed in essential oil content and composition in which trans-anethole, estragole, fenchone and limonene were the main constituents. Clustering method classified the ten fennel cultivars into 3 major groups. Moreover, PCA analysis showed great dispersion of these cultivars. The diversity identified in this study, especially from the three varietal types, showed that some cultivars are featured with several agro-morphological and chemical characteristics and could be further exploited as promising material for the creation of new varieties.

“…Ces propriétés sont dues essentiellement aux composés actifs dont la variation chimique présente un outil pour la caractérisation des plantes par rapport à leurs traits morphologiques. La variation de ces caractères morphologiques peut être fortement affectée par les conditions du site de collecte (Saran 2017). Dans ce contexte, le présent travail a pour objectif de comparer 16 populations de fenouil qui poussent à l'état spontané en Tunisie en se basant sur leurs critères morphologiques et de trouver les relations susceptibles d'exister entre ces traits, l'origine et la variation des huiles essentielles rapporté dans l'étude de Khammassi et al (2018) qui porte sur la variabilité des huiles essentielles des graines de Foeniculum vulgare et leurs activités antioxydante et antimicrobienne.…”

Fennel, Foeniculum vulgare Mill., is a very abundant aromatic and medicinal plant that grows spontaneously in several regions of Tunisia. The aim of this study is to describe the morphological variability of Foeniculum vulgare which seems to be essential to ensure a very appropriate sampling for a better exploitation of this species, especially since the morphological variability is often associated with a chemical variability of the active molecules. Therefore, our sampling concerned the different aerial parts of the species (stems, umbels and seeds) from sixteen provenances which are spread over different bioclimatic stages: humid, sub-humid, upper semi-arid and medium semi-arid. Several characters of morphological variability have been described for each plant part. For the stems : the length and the number of nodes and umbels per stem have been assessed, for the umbels: the diameter, the number of umbellules and the number of seeds per umbel have been described and for the seeds: the length and the seed width and the weight of 100 seeds were measured. The main results obtained were the subject of a principal component analysis. This study revealed a clear morphological variability linked to the different origins of tested plants.
