The Effect of 24–Epibrassinolide on vegetative growth of Sweet Ann strawberry seedling under lime stress conditions

The research was conducted in 2022-2023 in Yozgat. The study was set up to determine the responses of the Sweet Ann strawberry variety to different lime levels and the effects of 24-Epibrassinolide (24-eBL) applications on vegetative growth. It was observed that plant growth and development were negatively affected by the increase in lime doses. It was found that 24-eBL applications (BR) increased leaf and root fresh weight, iron and zinc uptake in calcareous conditions. In terms of leaf fresh weight, it was found to be higher in 0% Lime x 0 mg l-1 BR, 0% Lime x 1 mg l-1 BR, 0% Lime x 2 mg l-1 BR and 5% Lime x 0 mg l-1 BR applications compared to other applications, and it was determined that they were statistically in the same group. Regarding leaf area, the highest leaf area in the Lime x BR interaction was determined as 32.13 cm2 in the 0% lime x 0 mg l-1 BR combination and 33.60 cm2 in the 0% lime x 1 mg l-1 BR combination. Leaf chlorophyll content (SPAD) was statistically highest in 0% lime x 1 mg l-1 BR, 5% lime x 0 mg l-1 BR and 10% lime x 0 mg l-1 BR combinations. The highest stoma conductivity values were observed from 0% lime x 0 mg l-1 BR and 0% lime x 1 mg l-1 BR applications. Considering the lipid peroxidation (MDA) gave statistically significant the highest values 10% lime x 2 mg l-1 BR, 5% lime x 1 mg l-1 BR and 5% lime x 0 mg l-1 BR applications. While the highest N (%) and P (%) contents in the leaves were measured in the 0% lime x 0 mg l-1 BR application, the highest K (%) content was detected in the 5% lime x 1 mg l-1 BR application.
