TY - JOUR TI - Response of Germination and Seedling Development of Cotton to Salinity under Optimal and Suboptimal Temperatures AB - The objective of the study was to investigate the effects of salinitystresses (50, 100, 150, 200 and 250 mM of NaCl) on germination andearly seedling growth of six cotton varieties (Lydia, Carisma, Flash,BA151, BA525 and ST468) under optimum (25°C) and lowtemperature (18°C) conditions. Germination percentage, meangermination time, germination index, germination stress toleranceindex, seedling length, vigor index, seedling fresh and dry weight ofcotton varieties were investigated. Results showed that lowtemperature led to decreasing in germination and seedling growth,and caused retardation of mean germination time. Under suboptimaltemperature, germination percentage reduced from 86.3% to 77.8%and seedling length decreased from 12.02 cm to 5.36 cm. Eachincrease in salinity levels higher than 50 mM resulted in decreasingin germination and seedling growth parameters of cotton varieties.No seedling growth was observed at 250 mM of NaCl at 18°C. Cottonvarieties showed different tolerance levels to salinity, while theycould tolerate it up to 100 mM. It was concluded that Flash andST468 varieties exhibited better performance under salinity stressesboth at optimal and suboptimal temperatures.
