Abstract:

In this study, it was aimed to determine the effects of irrigation water containing different salt levels on the morphological characteristics of zinnia (Zinnia elegans). For this purpose, five different salt levels (control, 2 dS m-1, 4 dS m-1, 6 dS m-1 and 8 dS m-1) were established. As morphological characteristics, plant height, plant diameter, number of flowers, flower diameter, flower stalk length, flower stalk diameter, petal number, petal length, petal width, leaf thickness, leaf length and leaf width were measured. Irrigation was carried out at 7-day intervals. Soil moisture was monitored with pot weights. The research was carried out in Çanakkale Onsekiz Mart University, Faculty of Agriculture, in 2020. As a result of the study, while the number of flowers, flower diameter, number of petals, leaf thickness, leaf length and leaf width values of morphological features were found to be statistically different according to salt levels; plant height, plant diameter, peduncle length, peduncle diameter, petal length and petal width were found to be insignificant. When evaluated in terms of visuality, it can be said that there are significant differences between the treaments depending on the level of salt stress. According to the results of the research, it was revealed that the salt tolerance of the zinnia flower was partially low.
