Abstract Morpho-physiological evaluation of a crop’s genetic resources is necessary to find possible genotypes to include in breeding initiatives. The objective of this study was to identify heat-tolerant wheat genotypes among36 mutant lines using morpho-physiological indices. Seedlings of mutant lines and check varieties were grown under both normal (control) and heat-stress conditions in growth chambers. Data were recorded on root-shoot parameters (length, fresh weight, dry weight, and ratio), relative water content (RWC), stability of cell membrane, pigment content, and chlorophyll fluorescence. Two-way analysis of variance showed significant (p < 0.01, p < 0.001) variation among15 morpho-physiological features… More >

Abstract In this study, we analyzed the agronomic and physiological indicators of the leaves and roots of 60 hulless barley varieties under low-temperature treatment, identified the crucial indicators that can reflect the ability of hulless barley to tolerate low-temperature, and evaluated the ability of different hulless barley varieties to tolerate low-temperature. The results indicated significant differences in the agronomic and physiological indicators of 60 hulless barley varieties subjected to low-temperature treatment. Most of the agronomic indicators significantly decreased, whereas most of the physiological indicators significantly increased. However, the magnitude of changes in each agronomic and physiological… More >

Abstract Dōng líng căo, the dried aboveground parts of Isodon rubescens (Hemls.) Hara., is commonly consumed as a medicinal decoction or tea beverage. Natural beverages can be an important source of human dietary selenium (Se). However, how I. rubescens plants respond to exogenous Se remains unknown. In this study, a pot cultivation experiment was employed to investigate the phenotypic and physiological responses of I. rubescens plants exposed to Se. Fifteen days after applying different concentrations of sodium selenate to the soil, the Se enrichment capacity, growth indices, antioxidant capacities, and the content of flavonoids and diterpenoids were measured in… More >
