“…According to the coefficient of correlation, LA is correlated with LW and PL. The different kinds of correlation among different leaf traits in beech (Bayramzadeh et al, 2008) and other species were also reported by other authors (Yousefzadeh et al, 2010, Rakonjac et al, 2014Allahnouri et al, 2018). The high heritability indicated that the effect of genotype is more important than the environmental pressures.…”

Mohebi Bijarpasi, M., Rostami Shahraji, T., Samizadeh Lahiji, H., 2019. Genetic variability and heritability of some morphological and physiological traits in Fagus orientalis Lipsky along an elevation gradient in Hyrcanian forests. Folia Oecologica, 46: 45-53.The purpose of the present study was to evaluate the genetic variability and heritability of some morphological and physiological traits in Fagus orientalis Lipsky along an elevation gradient in northern forests of Iran. Beech leaves were sampled from southern and northern crown parts of healthy mature trees along an elevation gradient comprising sites situated at 700 m, 1,200 m and 1,700 m above the sea level. Our statistical analysis showed that the investigated traits differed significantly between the populations. The results indicated the lowest and the highest coefficients of variation for the high (1,700 m) and middle elevation populations (1,200 m) for leaf length, petiole length, leaf area, specific leaf area, dry weight, specific dry weight, leaf index and petiole index traits. With increasing elevation, mean leaf width, distance from leaf base to the leaf maximum width, dry weight and petiole index increased. The plasticity of leaf length, specific leaf area, specific dry weight, petiole index and petiole length peaked at middle elevation, and with increasing elevation, the plasticity of these traits declined. The distance from leaf base to the leaf maximum width had the highest coefficient of genetic (75.5%) and phenotypic (75.5%) variation. The heritability results showed that there were differences in all traits, and that the highest heritability was recorded for the distance from the leaf base to the leaf maximum width (99.95 %). The results suggest that the studied beech populations responded to the environmental changes by changing their leaf traits in different ways at different altitudes.

The study of endangered relict woody plants is a key component of biodiversity conservation strategies. In this regard, the purpose of the study was to compare anatomical features of the vegetative organs of relict Sogdian ash (Fraxinus sogdiana Bunge) growing in river valleys of the Sharyn State National Park in the Almaty region. In 2020-2021 young individuals of Sogdian ash were sampled, in the valleys of the Sharyn and Temirlik rivers to study, their root, stem, and leaf anatomical features for the first time. The lower and upper epidermis of F. sogdiana leaves were thicker in individuals growing at the Sharyn site than at the Temirlik site. In contrast to that, the thickness of the mesophyll was thicker in leaves from the Temirlik site. The cross-sectional area of the conductive bundles of plants were larger in trees from the Sharyn site. The morphometric parameters of the stem also had different results. The diameter of the roots were twice as large in Sogdian ash trees growing at the Sharyn site, likely due to the growing conditions, since the soil of the Sharyn River valley is meadow, stony and pebbly, compared to the Temirlik River, which is a deposit of red clay mixed with crushed stone and rock remnants. Since Sogdian ash is drought tolerant dry air well, due to its resistance to heat and soil salinity, it can be recommended in order to preserve biodiversity, for landscaping, and for improving ecosystem conditions.

“…Furthermore, they point to the importance of considering changes at the whole plant level, since the energetic demands on individual tissues are likely different and therefore the tradeoff between development and defence (success) plays a significant role. Because of the natural variability in not only aperture (dynamics) but also cell features of leaf epidermis (stomata), the nature and efficiencies of responses to (metal) stress are probably highly complex and are relevant not only for metal uptake by roots but even more by stomata [6,57].…”

Heavy metals perturbate water balance in plants and hence impact stomatal aperture. After longer exposure, stomatal development also is affected, and stomatal density and size can change. Two soybean (Glycine max) varieties were experimentally selected for contrasting tolerance to arsenic and cadmium. For these cultivars, natural variability in leaf epidermal cell parameters was detected. Pot plants at first assimilating leaf stage were exposed for 10 days to 5 mg kg-1 soil As 3+ and 50 mg kg-1 soil Cd 2+ (respectively). Metals accumulated primarily in roots and exerted relatively low impact on biomass. Despite this, we observed diverse adjustments of stomata and pavement cells. In cv. Bólyi 44 the stomatal size decreased upon stress treatment, possibly to avoid further water loss. In contrast, the other cultivar Cordoba uses larger stomata that might be advantageous in gaining further resources. The observed responses varied depending on leaf type. In addition, dorsoventral stomatal responses in width, yet undescribed under metal stress, were observed. Our data show that leaf epidermal cell adjustments are flexible components of plant defense even at low metal doses, and possibly help to compromise the structural and functional needs of plant (tissue) under metal stress.
