Abstract:
The experimental was carried out in (2021) in Barsheen research station (Hamah) to identify the influence of water and alcoholic extracts and essential oil of three species of thyme ( T.vulgaris, O,syriacum, T.syriacus) on apple fruits (golden delicious) that stored in a vegetable refrigerator on heat (+1,-1 Cْ) by use three concentrations of each extracts for the three species with three replication: 1- Water extract (125, 250, 500) ppm -2- alcoholic extract (75%) (125, 250, 500) ppm -3- Essential oil (0.5%, 1%, 1.5%). The experimental was putted in FRCBD design, and the statically analysis showed that there was significant differences between the studied treatments, and the treatment of T.v oil (1.5%) was the least of infection percentage (3.5%) and the highest percent control (73.3%) comparing with the control treatment (only water). Then alcohlic extract of T.v (500 ppm) with infection percentage (3.9%) and percent control (70.6%). While between the species T.v plant achieved the least infection percentage on average (3.9%) and percent control avg (70.6%), after it O.s (11.5%) with percent control avg (14.3%). also the treatment Oil (1.5%) was the best with infection percentage avg (4.9%) and percent control avg (62.9%), then the alcoholic extraction (500 ppm) with infection percentage avg (5.03%) and percent control avg (61.9%) without significant variant between them. That’s certificate the biotic activity of different thyme extracts and the ability to reduce the fungi infections in the fruits refrigerators.
Keywords: Infection Percentage, Water And Alcoholic Extracts, Essential Oil, Thyme.
