The Effect Lead Stress on the Early-Stage Development of Solanum melongena L. Seedling

The effects of plant growth promoting bacteria (PGPB) application on shoot and root lengths, root thickness and root lateral numbers of aubergine (Solanum melongena) seedlings in a lead stress environment were investigated. Also a control group was formed in addition to lead and bacteria conditions. In this study Stenotrophomonas maltophilia (TV14B) was used. Pb [Pb(NO3)2] (control, 50 and 100 ppm) was used for created abiotic stress for this experiment. Random bloks were designed for this research with 3 repetitions. 10 Solanum melongena seeds were used in each replication. While no value was obtained in root lateral measurements, no difference was detected at the level of statistical significance between shoot length values. Statistically significant differences were detected between root length values at the 1% significance level and between root thickness values at the 5% significance level. It was noted that root thickness increased under lead stress conditions, root lengths increased with the first dose of lead application, giving the expected results under stress conditions, but elongation increased less than the control group plants with the second dose of lead application.
