This article determines the possibility of ejaculation of bare seeds from the working chamber of the genie using auxiliary ejaculatory devices. Based on theoretical and experimental studies, results were obtained to improve the quality of fiber, seeds and gin productivity in the allocation of bare seeds from the working chamber. Based on the results of a full-factor experiment, graphs were constructed of the time spent on exposed seeds on gin productivity, the number of revolutions of vas differencing devices and the number of exposed seeds.

The catalpa tree is a member of the family Bignoniaceae, a species of catalpa. Representatives of this family consist of trees, shrubs, lianas and grasses, and are distinguished from other members of the family by their ornamental flowers and unusual leaves. There are regions with different climatic conditions, and in the soil and climatic conditions of the experimental cities of Tashkent and Nukus in Uzbekistan, it is important to select the composition of tree species resistant to various environmental factors. In the soil and climatic conditions of different regions of Uzbekistan, along with ornamental native plants, the widespread use of tree species introduced to our country will certainly bear fruit. The results of the study show that the use of Catalpa species in landscaping should take into account their bioecological properties. In Tashkent, the Catalpa speciosa Walder ex Engelm can be widely recommended for semi-shaded areas and in the soil-climatic conditions of Nukus for seedling breeding of Catalpa bignonioides Walt.

The loss of the product during post-harvest practices in agriculture is one of the most common problems that threaten food security today. Identifying and eliminating the causes of post-harvest losses is the best strategy to increase the efficiency of the farms and farmers who grow the product and ensure food safety, rather than using additional resources to increase the volume of production of any type of product. World’s yearly table grape production is 16.5 million tons. Producing areas are China, Turkey, Europe, Brazil, Chili and United States. Some popular grape varieties are Thompson Seedless, Flame Seedless, Crimson Seedless, Red Globe, Ruby Seedless, Red Seedless, Muscat and Sugraone. Although in recent years different reviews have described technological advances in maintainingthe quality of table grapes during postharvest, the mechanisms through which they exert theirbeneficial effects require an in-depth review. Thus, the present work aims to review existing literatureon the different potential mechanisms, giving special attention to molecular mechanisms regulatedby the postharvest treatments applied in order to improve table grape quality. Although we havemade an effort to review the mechanisms behind different postharvest treatments, it is important tohighlight that most published studies up until now examining both the effectiveness of treatmentsand their mechanisms, have used the modification of storage atmosphere composition as the onlypostharvest treatment.
