“…The highest coefficient of variation was observed for the surface (S) in the Azla watershed which consists of coppice and natural populations. This same observation was made for Croatian ecotypes [13]. In contrast, the least variable parameter was the shape ratio LL/LW, which is explained by the stability of the shape ratios [6].…”

For decades, local and traditional species have been neglected and replaced by industrial and improved species. Sweet chestnut 'Castanea sativa MILL.', found in a small area in northern Morocco, is no exception. Indeed, Moroccan ecotypes are neither classified nor characterized. This study aims to evaluate the local genetic resources of Castanea sativa MILL. via multivariate analysis of morphometric parameters of leaves. The study involved 6200 leaves from 31 villages in 3 regions; 10 trees/village and 20 leaves/tree were sampled. Then eight morphometric parameters were analyzed: lamina length (LL), lamina width (LW), petiole length (PL), distance from the base of the leaf to the widest point of the leaf (DBW), surface (S), perimeter (P), and ratios LL/LW and LL/DBW. Analysis of the descriptive statistics within and between ecotypes initially showed a large variation in the ten parameters studied. This finding was supported by analysis of variance (ANOVA) which revealed a very highly significant difference (p < 0.0001) for all parameters. Indeed, the analysis of agglomerative hierarchical clustering (AHC) made it possible to group the studied populations into 3 distinct groups based on the surface. Overall, the high level of variability in leaf morphometric parameters indicates that the region is an important center of genetic diversity which assessment is crucial for the implementation of conservation and enhancement strategies for this heritage.

“…Leaf variability is greatly influenced by various microclimate factors, their position on the shoot and tree, and the type of shoot on which they develop [50,[55][56][57]. In this study, those sources of variability were attempted to be reduced by collecting all leaves from the external sunlit part of the tree crown from short fertile shoots.…”

The paper studies the morphological variability of the service tree populations in the continental and Mediterranean regions of Croatia. The inter-and intra-population variability, as well as eco-geographic population differentiation, was established on the basis of eight measured morphological characteristics of two types of leaflets (lateral and terminal) and two derived ratios, using descriptive and multivariate statistical methods. The conducted research established a high variability of morphological characteristics. In comparison with lateral leaflets, terminal leaflets showed a higher degree of variability for the majority of the studied variables. The differences between the trees within populations, as well as the differences between populations, were confirmed for all studied characteristics. The study also confirmed a trend of population variations according to the eco-geographic principle. Populations from climatically different and geographically distant habitats, in other words from the Mediterranean and the continental region, differed in the majority of studied characteristics. In addition to the established pattern of ecotypical variability between the continental and the Mediterranean regions, the clinal variability with regard to altitude and mean annual temperature was also confirmed. Small, although statistically significant clinal variability with regard to the longitude was recorded for two measured characteristics. The conducted study provided insights into the variability of the service tree populations in Croatia, which is a basis for further research that should be implemented in order to produce guidelines for the breeding and conservation of genetic resources of this rare and endangered noble hardwood species.

“…These signs reflect the degree of plant resistance, because the leaves are the most important organs of photosynthesis and transpiration (Sahin and Soylu, 1991;Bruschi et al, 2003;Pinto et al, 2011;Mensah, 2012). These characteristics are important for genotypes identification base on the observation of morphological characteristics of which expressions are largely influenced by developmental, environmental and cultivation factors (Serdar and Kurt, 2011;Poljak et al, 2014). Many authors use morphological analyses to estimate the variability of Castanea sativa and which confirm that the leaf parameters can be appropriate variables for establishing the level of genotype variability (Aravanopoulos et al, 2001;Aravanopoulos, 2005;Bolvansky and Uzik, 2005;Álvarez-Álvarez et al, 2006;Ertan, 2007;Zarafshar et al, 2010;Serdar and Kurt, 2011;Mujagić-Pašić and Ballian, 2012;Poljak et al, 2014;Atefe et al, 2015).…”
