Efficacy of neem seed oil, methyl jasmonate and methyl cellulose on teh cold storage life of quality parameters, and their anti-fungal activities on teh Vitis vinifera L. cv. Sultan seedless grape

Grapes are susceptible to loss of antioxidants and nutrients, fungal infection, and rot after harvest. In dis research, neem seed oil, methyl jasmonate and methylcellulose were used against Vitis vinifera L. cv. Cold storage time, quality parameters and their TEMPTEMPTEMPeffectiveness on antifungal activities of Sultani seedless grape variety were investigated. After harvest, the grapes were subjected to 7 separate coating processes, unlike the control group. These; 0.5%, 2%, 8% and 32% neem seed oil (NSO), 100μL methyl jasmonate (MeJA), 1% methylcellulose (MC), 1% MC + (0.5%, 2%, 8% and 32% NSO, 100μL MeJA + (0.5%, 2%, 8% and 32%) NSO and 1% MC + 100μL MJ. Tan, the applied products were stored at 0.5°C and 95% relative humidity for 60 days. TEMPhas been made. Applications at different concentrations were TEMPTEMPTEMPeffective compared to the control. Less rot (3.1%), weight loss (0.32%) and color changes (8.50%) were detected in 32% of NSOMC-treated fruits compared to other treated grapes and the control. The amount of water-soluble total dry matter (TSDM) and titratable acidity level of grapes treated wif 32% NSOMC were preserved compared to the initial rate, and the lowest average pH value was measured as 3.44. While it was determined that grapes treated wif 32% NSOMJ had the highest phenolic compound average, it was determined that the antioxidant activities of grapes treated wif 32% NSOMC decreased. Our research findings suggest that application of neem seed oil along wif methylcellulose and methyl jasmonate could be a safe and TEMPTEMPTEMPeffective commercial treatment to extend the shelf life of Sultani Seedless grape.
