“…There are around 30 different species, with Capsicum annuum L. being the most widely spread and cultivated [ 2 ]. They are native to the tropical and subtropical Americas and thus susceptible to various abiotic stresses [ 3 , 4 , 5 ]. Chilies and peppers are usually grown in greenhouses whereby constant irrigation is required to ensure optimum water availability.…”

A total of four Capsicum annuum L. genotypes (‘Caro F1’, ‘Berenyi F1’, ‘Somborka’ and ‘Novosadka’) were exposed to two intensities of salt stress. We observed a significant decrease in the sugar content in all salt stressed treatments, except for the sucrose content of the pericarp of the ‘Caro F1’ cultivar. Salt stress had a largely negative effect on the total and individual organic acid content, although the effect differed among cultivars. Using high performance liquid chromatography coupled with a mass spectrometer, most phenolics were identified in the pericarp (18), followed by the placenta (7) and seeds (8). Treatment with 40 mM NaCl caused the highest increase in individual phenols, followed by treatment with 20 mM NaCl. The cultivar ‘Berenyi F1’ was less affected by salt stress treatment than the other three cultivars in terms of content of individual and total phenols. Salt stress increased the content of capsaicinoids in all the cultivars. The pericarp of the cultivar ‘Novosadka’ showed 17.5 and 50 times higher total capsaicinoid content than the control in the 20 mM and 40 mM NaCl, respectively. With the results of several metabolite groups, we confirmed that the reaction and metabolic content to salt stress within the genus Capsicum is genotype-, fruit part-, and salinity level-dependent.

“…Significant differences in shoot dry weight and root dry weight between stressed and control plants indicated that drought stress has inhibited plant growth and reduced assimilate production in the tested curly peppers. Evidence also shows that drought stress reduces dry matter in curly peppers (Okunlola et al 2017;Widuri et al 2020). Many researchers stated that drought tolerance genotypes have a small decline in dry weight under drought stress conditions (Ahmed et al 2020).…”

“…Some researchers reported that drought stressinduced stomatal closure, reduced transpiration, increased oxidative stress, interfered with photosynthesis, and changed chlorophyll contents (Ying et al 2015;Liu et al 2017;Nemeskéri and Helyes 2019;Almuwayhi 2021). The morphology changes of curly pepper also occurred during drought stress, such as reduced plant growth, flower abortion, declined biomass, and yield (Mardani et al 2017;Rosmaina et al 2018;Widuri et al 2020). The magnitude of drought stress impact on the crops' morpho-physiological depends on genotypes species, crop development stages, stress intensity, and stress duration (Saeidi and Abdoli 2015;Rosmaina et al 2018).…”

Abstract. Rosmaina, Ridho A, Zulfahmi. 2022. Response of morpho-physiological traits to drought stress and screening of curly pepper (Capsicum annuum) genotypes for drought tolerance. Biodiversitas 23: 5469-5480. Developing drought-tolerant genotypes are required to face drought condition that often occurs. The study aimed was to assess the growth, biomass, yield traits, and gas exchange of fifteen curly pepper (Capsicum annuum L.) genotypes under normal and drought-stress conditions and to determine the key traits as indicators for selecting and identifying the drought-tolerant curly pepper genotypes. Fifteen curly pepper genotypes were cultivated under normal and drought-stress conditions. Twenty-one morphological and physiological traits were recorded in the reproductive phase. The data obtained were subjected to analysis of variance, Principal Component Analysis (PCA), and UPGMA dendrogram cluster analysis. This study showed that drought stress conditions significantly reduced plant growth, biomass, yield characters, photosynthesis rate, stomatal conductance, transpiration rate, and mesophyll conductance compared to normal conditions. Based on PCA analysis, stomatal limitation, mesophyll and stomatal conductances, root length, photosynthesis rate, fruit weight per plant, chlorophyll b, number of fruit, and transpiration rate were established as indicators for screening drought tolerant genotypes. The UIN-70 and UIN-65 were highly drought-tolerant genotypes according to the MFVD index. UPGMA dendrogram displayed clustering of the curly pepper genotypes consistent with the genotype's cluster based on the MFVD index. This study's findings can be utilized to improve curly pepper's drought tolerance in the future.

“…Under water deficit, the main resistance mechanisms involve avoidance and stress tolerance strategies ( Polle et al, 2019 ). Stomatal closure induced by the abscisic acid is an avoidance response to drought and helps to reduce water vapor loss through leaf transpiration, but hinders the diffusion of other gases, restricting the photosynthetic process ( Devi & Reddy, 2020 ; Widuri et al, 2020 ). To adjust to the low CO 2 availability in this condition, the photochemical efficiency can be reduced.…”

Background Soybean is the main oilseed crop grown in the world; however, drought stress affects its growth and physiology, reducing its yield. The objective of this study was to characterize the physiological, metabolic, and genetic aspects that determine differential resistance to water deficit in soybean genotypes. Methods Three soybean genotypes were used in this study, two lineages (L11644 and L13241), and one cultivar (EMBRAPA 48-C48). Plants were grown in pots containing 8 kg of a mixture of soil and sand (2:1) in a greenhouse under sunlight. Soil moisture in the pots was maintained at field capacity until the plants reached the stage of development V4 (third fully expanded leaf). At this time, plants were subjected to three water treatments: Well-Watered (WW) (plants kept under daily irrigation); Water Deficit (WD) (withholding irrigation until plants reached the leaf water potential at predawn of −1.5 ± 0.2 MPa); Rewatered (RW) (plants rehydrated for three days after reached the water deficit). The WW and WD water treatments were evaluated on the eighth day for genotypes L11644 and C48, and on the tenth day for L13241, after interruption of irrigation. For the three genotypes, the treatment RW was evaluated after three days of resumption of irrigation. Physiological, metabolic and gene expression analyses were performed. Results Water deficit inhibited growth and gas exchange in all genotypes. The accumulation of osmolytes and the concentrations of chlorophylls and abscisic acid (ABA) were higher in L13241 under stress. The metabolic adjustment of lineages in response to WD occurred in order to accumulate amino acids, carbohydrates, and polyamines in leaves. The expression of genes involved in drought resistance responses was more strongly induced in L13241. In general, rehydration provided recovery of plants to similar conditions of control treatment. Although the C48 and L11644 genotypes have shown some tolerance and resilience responses to severe water deficit, greater efficiency was observed in the L13241 genotype through adjustments in morphological, physiological, genetic and metabolic characteristics that are combined in the same plant. This study contributes to the advancement in the knowledge about the resistance to drought in cultivated plants and provides bases for the genetic improvement of the soybean culture.
