Eureka! Institutional Repository

The present study was carried out in the educational greenhouse of ATEI Farm. The purpose of the research was to investigate the alleviation of the symptoms of boron toxicity with ascorbic acid. 64 strawberry plants were used divided into 8 control groups with 8 plants in each group. 8 operations were performed, 2 of which were the controls. Toxicity was induced in each group with different boron concentration in 3 doses. At the end of the 3 doses, a collection of fruits for analysis was performed, and then an ascorbic acid treatment was performed in 3 doses. Fruit and leaves were then harvested for further analysis and determination of the toxicity and efficacy of ascorbic acid. Analyzes were performed to determine minimum fluorescence (F0), maximum fluorescence (Fm), Performance Index (PI), Area Index, photosynthesis rate (A), leaves stomatal conductance (gs), intracellular CO2 concentration (Ci), rate of transpiration (E), lipid peroxidation (MDA), released hydrogen peroxide (H2O2), chlorophylls a+b, and flavonoids. The analyzes showed apparent strain of plants and their functions from B, but they also showed relief of this strain by the addition of ascorbic acid. The best-effect procedure was that with the addition of 10 mmol B and 0.02 g of ascorbic acid.
