The investigations were conducted on the fields of the Kazakh Research Institute of Potato and Vegetable Growing located on the northern slope of the Zailiysky Alatau, 40 km to the west of Almaty city, under irrigation conditions. The soil of the experimental site is dark chestnut with medium-loamy structure. 37 carrot accessions with different geographic origins were the object of the study in the nursery of the initial breeding forms to evaluate their productivity and field resistance to foliar diseases such as Alternaria, Powdery Mildew. When symptoms expressed maximally 1.5 months before the harvest of carrot, visual assessment of leaf surface damaged by foliar infections was carried out according to the scale of infection, where 0 meant no damaged leaves; 1 meant very light damage (1-10% of leaves); 2 meant light damage (11-25% of leaves); 3 meant medium damage (26-50% of leaves); 4 meant severe damage (over 51% of leaves). The visual observation showed that two breeding accessions CR00655 and CR01253 had immunity to powdery mildew that maximally spread out over other carrot accessions approaching of 100% of damage of leaf surface with the score from 1.8 to 3.8 points, when disease developing from 45.0 to 93.8%. Alternaria spread on carrot plants not very intensively, only 17% of plants in the nursery were hardly attacked at 0.1-0.4 points as scored. The correlation analysis showed the absence of any link between characteristics of productivity and damage parameters caused by foliar diseases at r=0,005-0,225.

Experiments were carried out at FGBNU VNIIO in 20112016. The aim of the study was to analyze the influence of different types of organic dormancy caused by various factors on seed quality of some representatives of umbellifer crops. The objects of the study were seeds: parsnip ‘Kulinar’ (Pastinaca sativa L.); carrot ‘Rogneda’ (Daucus carrota L.); root parsley ‘Ljubasha’ (Petroselinum crispum (Mill.) Nyman ex A.W. Hill.); root celery ‘Kupidon’ (Apium graveolens L.); coriander ‘Yantar’ (Coriandrum sativum L.) and dill ‘Kentavr’ (Anethum graveolens L.). In all seeds studied, the speed of embryo growth was decreased by 30% or0.03 mma day. Under influence of the induced dormancy caused by incubation in extract from dill seeds, the speed of embryo growth in all species was decreased by 94-97% on average. The process of germination of just picked seeds in all crops studied showed itself in reduction of germinated seed number by 54% as compared with control variant. Under the effect of incubation at high temperature the seeds of parsnip and root celery didn’t germinate, whereas the germination in the seeds of coriander, root parsley and carrot was decreased by 51%, 47% and 46%, respectively as compared with control. There is no germination observed in parsnip, carrot, root celery and coriander under influence of induced dormancy caused by incubation in extract from dill seeds. In this case, the germination of seeds of root parsley and dill was 8.1% and 15%, respectively. The Pearson correlation between the speed of embryo growth and percent of seed germination showed the significant and positive relationship in the range 0.706-0.952. Analysis of variance (ANOVA) showed that induced by temperature or allelopathic dormancy had impact on the speed of embryo’s growth in the crops studied, where factor effect was 89-86% depending on type of dormancy. Analysis of variance between the factors of dormancy and germination revealed that all types of dormancy analyzed had much influence on germination in these crops. The factor effects for primary, temperature induced, and induced allelopathic dormancy were 98% (F=1590.3; P=< 2x10-16), respectively.

The modern technologies for production of high yield in vegetable crops in agroindustrial complexes provide the development of optimal conditions for plant nutrition including the application of microelements and biologically active substances (BAS). The study of productivity in tomato with application of microelements and biologically active substances were carried out in unstable moisturization in Stavropol region at the facilities of Educational and Experimental Station FSBEI HE Stavropol SAU in 2015-2016. The aim was to study productivity in tomato with application of microelements and biologically active substances on the basis of calculated norms of fertilizers. The objects of the study were tomato hybrid ‘Premium F1’, Agromix, and different BAS. Calculated dose of fertilizers on predicted tomato yield of 80 t/ha according to experimental protocol was N130Р150К170, where this norm was regarded as a control. Mineral fertilizers were added to basic fertilizer and included as extra feeding supplied through drip irrigation system. Agromix was applied as part of foliar dressing through drip irrigation, while BAS was used only as foliar dressing. The data on development of vegetative and generative plant organs, biochemical composition and yield characteristics of tomato fruit were analyzed. As a result of the study, it was shown that experimental tomato plants significantly differed from control ones not only by yield capacity and quality, but also the morphological characteristics. With application Agromix and BAS the area of leaf surface, stem diameter, degree of fruit formation, average fruit weight increased by 0.004-0.04 m2, 0.2-0.3 cm., 39%, and 8-16 g., per plant respectively. With application of N130Р150К170, Agromix, amino acids and epibrassinolide in different combinations, the dry matter content in fruit, sugar content, sugar and acid index and vitamin C content were increased as compared with control by 0.07-0.15%, 0.12-0.26%, 1.21.7 and 0.6-1.3 mg %, respectively, while nitrate content was decreased by 14.0-17.5 mg/kg. Application of microelements and BAS in the system of tomato plant nutrition increased tomato yield by 0.6-4.3 t/ha as compared with control variant. The highest yield was obtained in the experiment with combined application of N130Р150К170, Agromix, amino acids and epibrassinolide in plant feeding system. As a result of study, it was shown that highest productivity in tomato was obtained with combined feeding with microelements and BAS on the basis calculated norms of fertilizers.

The study was carried out at All-Russian Research Institute of Vegetable Growing (GNU VNIIO) in 2013-2016. The objects of the study were seeds of carrot taken from variety ‘Rogneda’ regarded as a standard, breeding lines 690V, 690P and 753. The aim of the work was to study the dry weight of carrot-embryos and calculate the main characteristics regarding their variability among different accessions that were obtained through both inbreeding and outbreeding methods. Mean values of the sample for seed embryo weight differed among different carrot accessions and breeding lines in the range from 36.8 μg to 17.0 μg in ‘Rogneda’ and line 753, respectively. Moreover, there is no strong derivation of mean value from median within each sample of the breeding line was observed. The derivation of mean value from median was 0.2 μg in ‘Rogneda’. The least embryo weight 14.0 μg was observed in breeding lines. The coefficient of variation for embryo weight varied in the range from 10.4 to 14.2 and reached 25.1 % in ‘Rogneda’. The method of maximum likelihood was used to reveal correspondences of experimental function of distribution in embryo weight in seed population of accessions studied and normal distribution. Statistical high-order moments (asymmetry and excess) of sample in carrot had insignificant shift. The highest values of asymmetry and excess were observed for selected measurements of embryo weight in breeding line 690V. The experimental data observed may lead to previous conclusions about significant difference among four carrot accessions in embryo weight and its character of variability. Thus, such a main morphological element-the embryo-in the seed is also very probably subjected to the strong inbreeding depression. Morphometrical parameter of embryo weight may be interesting not only for seed production and seed study, but also for breeding program, and regarded as an inherited trait that can be improved.

M. I. Mamedov | M. R. Engalychev | A. E. Joss
Physalis (Physalis L.) is grown worldwide. P. pubescens L. is most widespread in Russia. The analysis of development of biochemical properties in fruits of P. pubescens L. in temperate climate was presented in the article. The berries of physalis have acid reaction and high nutrient value due to polyphenols, carotenoids that give orange color, also contain moderate quantity of vitamin C. Moreover in the berry juice there are significant quantities of potassium, phosphorus, calcium, magnesium, zinc, copper, iron, manganese and boron. P. pubescens L. is a promising exotic crop that can be used for production of functional foodstuffs. Physalis berries are usually used as fresh vegetables for salad recipes, providing the sweet and sour balanced taste. The whole fruit berries are also processed into syrups or dried, so that they are regarded as ‘elegant raisins’. Our study showed that the dry matter content was 15.5% in cultivar ‘Zolotaya Rossiyp’ in temperate climate, while the ascorbic acid content was 9.9 mg per 100 g. of wet weight. In temperate climate 318 mg GAE/100 g. polyphenols were accumulated in the berry of P. pubescens L. The titrated acidity of ‘Zolotaya Rossiyp’ berries was 0.90%, at pH 4.72. The level higher than 4 confirms the low acidity. This can be explained by the fact of presence of organic acids as a free forms in the berry juice.

One of the main directions of the food industry development is the production of functional food products. Changes in the human’s diet structure cause that none of population group does receive necessary amount of vitamins, macro and microelements in healthy routine diet. To solve this problem, food stuffs enhanced by different ingredients enable to improve the biological and food value. The pumpkin is a valuable source of such important substances as carotene and pectin. Addition of garlic and hot pepper ingredients to process of pumpkin pickling enables to enrich the products with carbohydrates, proteins, microelements, which have low or no content in the pumpkin fruit. Therefore, the study of the influence of the different quantities of garlic and hot pepper additions on chemical composition of finished product is very important. The influence of plant additions used on chemical composition of finished product had been well determined. It was shown that through increased doses of garlic and hot pepper ingredients as compared with control, the carotene and dry matter content then decreased by 1.16%-3.43% in pickled pumpkin, while the pectin content depended on added component. The highest pectin content, 0.71% was observed at addition of 10 g. garlic ingredient per 1 kg. of raw matter, that was 4.1 times higher than control. With increased addition of hot pepper ingredient the pectin accumulation was decreasing from 0.58% in control to 0.36% in variant 10g. per 1kg. of raw matter.

O. N. Krylov | O. Y. Abisheva
Economical efficiency of agricultural industry is a major characteristic of the level of development of an enterprise. A profit from product sale depends on volume and structure of product sales, self-cost as well as the level of sales price. Thus, the gross revenue from cultivated crops and vegetable cultivars can be observed at the time of fruit harvesting. The total sum of the gross earnings from the harvest, determining the efficiency of enterprise can be calculated as a product of values of daily price and mass of total harvest. There are no challenging points in the condition of permanent price and vegetable harvest. Even the registration of average-sales prices for vegetable doesn’t make the production difficult. But real market situation essentially differs from accepted practice to register average-sales prices with relatively permanent vegetable harvest. The price indexes of sales for tomato and cucumber produced in greenhouse in Udmurt Republic with showing the dynamic of retail price for vegetables were presented in the article. It was shown that prices of tomatoes and cucumbers had the seasonal factor that meant weekly price wavering. The temporal row harvest of cucumber ‘Tseres F1’ and tomato ‘Admiro F1’ produced at Zaviyalovskiy greenhouse enterprise was described. The average derivation between nearest and last harvest was in the gap 23% to 29% in cucumber and reached up to 70% in tomato. The values of such derivations were occasionally provoked and determined by some inter-enterprise factors. The construction of trend lines for such series and further line evaluation with the aid of determination coefficient R2 showed extremely low quality of model of the kind y=a•x+b. The value of R2 cubic polynominals was in the limits R2=0.32-0.46. Essentially, plans for vegetable production, constructed on the basis of this linear model should be regarded as unsatisfied. According to the analysis presented above, it is worth concluding that the principles to plan the production process in greenhouse enterprises have to be changed. As an example, the use of tk value as a shift of harvest time for kcrop related to price maximum for the crop used can be very effective.
