Abstract:
In this study, the effect of two sodium chloride concentrations of 4 and 8 g/L on two marigold sparse petal and compact petal genotypes evaluated at germination and adult stages using factorial experiment based on randomized complete block design. There were differences between genotypes in some germination indices, vegetative and reproductive morphological and physiological traits. Some traits were reduced by increasing sodium chloride concentration to 8 g/L in both growing stages. Interactional effects of salt × genotype were significant on germination percentage and leaf water saturation deficient at seedling and adult stages, respectively. Sparse petal and compact petal genotypes were more tolerant to salinity in seedling and adult stages, respectively. Therefore, cultivation of compact petal marigold genotype in areas with water salinity problem up to 4 g/L NaCl is suitable and advisable.
