“…Image analysis was performed using ImageJ software (https://imagej.nih.gov/ij/). Stomata size (area) ([stomata width × stomata length × π] / 4), stomata density (number of stomata per area), and stomata index (ratio of stomata to total epidermal cells, including stomata and pavement cells) were then calculated (Cortan et al ., 2017).…”

Understanding the physiological mechanisms that control drought tolerance in crop plants is vital for effective breeding. In this study, we characterized drought stress responses in four sorghum cultivars exhibiting differential levels of drought tolerance at pre-and post-anthesis. Greenhouse-grown plants were subjected to two types of drought treatment, water stress (WS) and desiccant-induced water stress (DA), timed to occur at pre-and post-anthesis. Multiple physiological measurements were then made revealing varying responses among the experimental cultivars. The pre-and postflowering drought-tolerant cultivar P898012 showed a significantly higher net photosynthetic rate, higher transpiration rate, and greater stomatal conductance compared to the drought-susceptible cultivars at both pre-and post-anthesis. A significantly greater stomatal size was also detected in P898012, while the highest stomatal density was found in the drought-susceptible cultivar P721Q. Meanwhile, the two post-flowering drought-tolerant cultivars P898082 and B35 had a higher starch content and exhibited greater osmotic potential under post-anthesis water stress. Compared to WS and wellwatered control plants, a greater increase in root biomass was observed in P898012 under DA at pre-anthesis. This finding suggests that plants invested more assimilates into the roots under severe DA at pre-anthesis. Overall, our results show good conformity between drought tolerance in sorghum and key physiological mechanisms of stomatal conductance, root growth patterns, and starch accumulation, all of which act as coping mechanisms during critical drought-sensitive growth stages. | INTRODUCTIONDrought is one of the key abiotic stresses limiting crop productivity worldwide (Cha-um et al., 2012), affecting plant productivity by inducing stomatal closure, and thereby reducing photosynthesis (Németh et al., 2002) and growth (Bibi et al., 2012). With growing effects of climate change, the development of drought-tolerant and climateresilient crops is essential for survival under unfavorable environmental conditions and maintenance of high yield. Plants respond to water stress via a series of cellular events involving physiological, morphological and biochemical processes. Under water stress, photosynthesis decreases, osmotic potential is reduced, and consequently, the availability of photosynthetic assimilates and energy becomes limited. During pre-anthesis assimilation, the necessary resources for grain filling temporarily accumulate within the stem as non-structural carbohydrates such as starch, sucrose, monosaccharides, isoprenoids, and fructans (Schnyder, 1993;Jensen and Wilkerson, 2017). It has been suggested that genotypes that can synthesize and store large amounts of starch could potentially exhibit improved grain yield by mobilizing these reserves to the grains when photosynthesis is inhibited

Leaf stomatal traits variation within and among fourteen European beech (Fagus sylvatica L.) provenances

In the present study, variations of leaf stomatal traits for fourteen European beech provenances (Fagus sylvatica L.), originating from six countries (Bosnia and Herzegovina, Croatia, Germany, Hungary, Romania and Serbia), were evaluated at the inter-and intra-provenances levels. Ten stomatal traits (stomatal density (SD), guard cell length (LA) and width (WB), stomatal aperture length (La) and width (Wb), pore surface of guard cell (SPSLAWB), pore surface of a widely opened pore (SPSLaWb), coefficient (SSC), potential conductance index (PCI) and relative stomatal pore surface (RSPS)) were examined using methods of univariate (ANOVA and Tukey's HSD test) and multivariate statistical analyses (principal component analysis (PCA), discriminant analysis and cluster analysis). The results obtained provide significant insight into the genetic diversity and differentiation of European beech provenances and confirmed high genetic variability within and between examined European beech provenances, according to all examined parameters. Differences at the intra-provenance level had a bigger impact on most of the 938

“…Likewise, all species had abundant cuticular wax which would reduce transpiration in poplars growing in dry riparian regions [88]. In native populations of P. n i g r a of the Serbian alluvial zone, no differences were found in stomatal characteristics which could indicate that each of them has a similar combination of genotypes [89].…”

Riparian vegetation comprises plant communities that grow laterally to rivers and streams. They have multiple adaptations, which allows them to persist in these variable and dynamic habitats. This chapter focuses on the morphological and anatomical adaptations of vegetative organs, due to the fact that they are more vulnerable to environmental changes that occur in riparian ecosystems. We also discuss some dispersal mechanisms in riparian species exposed to flooding conditions. Most morphoanatomical adaptations in riparian plants reflect constraints imposed by long periods of waterlogging or complete submergence, as well as the high diversity of strategies that species have developed in order to cope with flooding. Furthermore, riparian ecosystems are being impacted by an increasing artificialization of rivers and banks with losses, or profound changes, in the natural riparian vegetation a problem that will increase with the ongoing climate change, and which must be contained. In order to reduce the vulnerability of these ecosystems, a deeper knowledge of the morphoanatomical attributes that make possible the successful adaptation of riparian flora is necessary so as to implement appropriate measures for the rehabilitation and sustainability of riparian ecosystems.
