| Materials and methods of work: In the laboratory, the yield and growth capacity of the
planted seeds of experimental plants was carried out in 3 variants. Option 1. When lighting at a distance of 0.5 m from the South-Eastern window of the laboratory room, at a temperature of complete moisture saturation (200C) ; Option 2. Saturated with full moisture, in the dark (180C) in a room with temperature; Option 3. In a catalyst with a stable temperature of 250C, completely saturated with moisture, is placed in a light thermostat. 1-3 embodiments, the fully ripe seeds; According to the variant, in conditions of full light-saturated temperature humidity of 200C, seeds of 10 pieces from the plant are placed on each Petri dish. To determine the yield and dynamics of seed growth, phenological observations of the intensity of their growth and development were carried out [5]. According to the results of the control, 5 seeds were produced from 10 pieces of planted cucumber seeds, the number of sifted seeds was revealed in the first 6 days and the average percentage was calculated (Fig.2). According to Option 2, the results of phenological observation of yield and intensity of extraction of experimental seeds of plants in a dark room with sufficient humidity, temperature 180C are given in the table below. In a dark room at a temperature of 180C, the intensity of absorption of seeds is predominant in the cucumber vegetation (4-piece), the slow dynamics of the absorption was carried out in seeds of tomato (1 pieces) (2- figure). Figure 2. The germination of cucumber under laboratory conditions Variant 1 the results of the study depicted a microscope К10Х20. The second study identified brief characteristics of diseases and pests of vegetable crops found in the greenhouse, their distribution and harmfulness. The symptom of the disease on the upper surface of the leaves is a light yellow, common spot, and on its lower surface-light gray. Infected leaves yellowish-yellow, liquefied and vegetable tendons. In the leaves of seed plants, in the classroom, in the Mouth of the flower, in bean leaves develop black, various sizes of spots. On the surface of the printed spots in the legumes, a transparent, white mold is formed, and in the rocks formed on them get sick. When sowing such breeds, an increase in morbidity develops, the fungus has spread diffusely, the scar sign is manifested in the leaves of the seed contribution. When stored in a warehouse on the outer leaves of the infected melon, white molds, common gray spots are formed [6,7]. When planting infected seedlings on crops, the development of the disease slows down. With abundant moisture content, the piece reproduces again, the sign appears on the lower green leaves (3- figure) |
