Investigation lysophosphatidylethanolamine and polyethylene glycol application on tomato plants

In this study, the effect of 4% PEG applications with 100 and 400 ppm doses of LPE on the physiological and morphological parameters of the Ikram tomato variety (Lycopersicum esculentum L) had been investigated.. The application had been made to the fruit in the form of spraying and irrigation to the soil. The content of proportional water content, growth parameter, chlorophyll and carotenoid, proline, soluble carbohydrate, total amino acid, SH groups, soluble protein, ascorbic acid, SOD, MDA and lycopene had been examined in the leaves samples. According to the results of the study, increase of fresh weight and proline content in LEP and PEG doses in fruit and soil applications, decrease of chlorophyll and MDA content had been seen. An increase in the amount of amino acids, an increase in all combinations of soil application, and a few increases in fruit application had been seen. There was an increase in SOD in fruit application and a decrease in LPE 100 in soil application. When we look at the amount of lycopene, the increase in the amount of lycopene in all combinations of LEP and the resulting fruiting in the fruits were observed while the increase in soil application was not observed. This difference between fruit and soil application shows the effect of LPE on fruit.
