Niğde ekolojik koşullarında farklı sulama düzeylerinin lavanta (Lavandula officinalis) bitkisi gelişimine ve yağ kalitesi üzerine etkilerinin araştırılması
This research was conducted in 2022 and 2023 in the application and research area in the open field of Niğde Ömer Halisdemir University Faculty of Agricultural Sciences and Technologies. A drought trial established on Lavandula officinalis plant, which includes 4 different irrigation levels (100% Irrigation, 66.6% Irrigation, 33.3% Irrigation, 0% Irrigation), 1 The experiment was created in a randomized block design with 3 replications and 45 plants in each replication. The research was conducted on lavandula plants planted in May 2018. Cow manure was given once after planting in 2018 and twice in 2019-2022. Cow manure applied once after weeding control, 1500gr/plant same for all plants. In terms of irrigation levels, since IRR 1 (100%), IRR 2 (66,6%) and IRR 3 (33,3%) and IRR 4 (0%) are statistically in the same group in many parameters, IRR-3 (33.3% ) irrigation level has been suggested considering the irrigation water saving. The aim of this study, which is planned and applied to measure the response of Lavandula plant to determine plant development and oil quality in field conditions and to determine the effectiveness of drought applications on plant growth and some physiological stress parameters with the application of different irrigation levels. When the data obtained in the research were examined, it was found that growing environments and irrigation levels had an effect on the physiological development of lavender. As a result of the research, it was determined that Lavandula could be grown successfully with less irrigation and fertilization in the Niğde region.
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.
