Abstract

In this study, plant growth parameters of 16 landrace dwarf common bean genotypes collected from Western Mediterranean region of Turkey at different salinity levels were investigated. The salt concentrations were applied 0.5 (regular irrigation water), 2, 4 and 6 dSm-1. The study continued until the first flowering was observed in the plants. The results of analysis of the variance revealed significant variations among different salinity levels, genotypes and interaction effects of salinity levels × genotypes for morphological characters. According to statistical analysis results, there was no correlation between stem diameter and other morphological characters. It was determined that there was a statistically significant positive strong correlation between plant height and plant dry weight (r=0.703). There was a moderately statistically significant positive correlation between all other characters. The increased salinity level negatively affected the vegetative growth of the common bean genotypes. However, low doses of salt have promoted development in some genotypes (AGB10, AGUN25, BY4, BY24, IYOZ10). However, a slight increase in salt level caused a sudden drop in development. These genotypes are thought to be suitable for soils with low salinity. The genotypes gave different responses to salt stress and ISGA1 and ISGA10 genotypes gave the best results. Besides them, prominent genotypes were detected as AGUN6, BKARA2, AGB10 and IYOZ10.
