The tomatoes have highest share in Romanian crops from protected spaces (greenhouses, solariums). The grafting is an agronomical technique that induces or improves some qualities of the tomato cultivars (resistance to soil diseases and pests, resistance to abiotic factors, quantity and quality of fruit production). The research was aimed the establishing of the technological stages for producing of scion and rootstock seedlings from L. esculentum species, to obtain compatible phenotype when is grafted. The observations of this research were conducted on Department of Horticultural Cultures in Protected Spaces from Horting Institute Bucharest. The experience was carry out on a cultivar collection consisting from L. esculentum plants: scions (‘Siriana’–F1 hybrid and ‘Buzău 1600’– variety), creations from the germplasm bank of Research and Development Station for Vegetable Growing Buzău Romania (VDRS Buzău) and rootstock (‘Groundforce’–F1 hybrid). The plant diameters were correlated for a grafting by the annexation method, cutting at 45 degrees. The grafting was performed successfully. The technological steps have achieved phenotypic compatibility of the symbiotes when was the grafting by annexation. The technology for producing of scion and rootstock seedlings at these Romanian tomatoes (‘Siriana’ and ‘Buzău’ 1600) was established for the crops in protected spaces in south area of Romania.

Vegetative Multiplication

The tomatoes are valuable vegetables, with highest share in Romanian crops from protected spaces. The grafting is a vegetative multiplication method that induces or improves some qualities of the plants (vigor, resistance to soil diseases and pests, resistance to abiotic factors, quantity and quality of fruit production). The research aim has been to establish the technological stages for producing of Dutch scion and Romanian rootstock seedlings from Solanum lycopersicum L. species, to obtain some compatible phenotypes for grafting. This research has been conducted in a greenhouse of the Horting Institute Bucharest. The experience was carried out on a tomato cultivar collection consisting from a Dutch scion (‘Abellus’ F1 hybrid) and three Romanian rootstocks (‘L542’, ‘L543’, ‘L544’). The scion and rootstock diameters have been correlated for manual grafting, cutting at 45 degrees and using the method of splice in silicone tube. The technological stages for obtaining grafted tomatoes have been established for the researched genotypes. These tomato combinations have been compatible for vegetable crops in protected spaces in the south area of Romania.

AbstractThe study was performed at the Experimental Station of Agriculture - Khan Krum in the period 2018-2019. The experimental plantation was established in 2001, the early Bigareau Burlat, middle early Bing and the late Germersdorfer and Van were tested. The planting material was produced on a mahaleb rootstock. The distance of planting was 6 meters interrow spacing and 5 meters intrarow spacing. The experiment was based on three replications each of them reported on a separate tree. When analyzing the frost percentage of flowers, 400 blossoms were taken from three levels of the crown of each tree, the same number of fruits were taken to determine the cracking percentage. Percentage of damaged blossoms, yield kg/ha and percentage of fruit cracking as a result of fallen rains during harvest were established. The purpose of the study is to investigate the influence of abiotic factors on the yield and quality of four sweet cherry cultivars. In this regard, the frost percentage in the range of values was 67,3 - 100%. Bigareau Burlat yield was not obtained, and it was relatively low from Germersdorf and Bing (20,1 - 24,6 kg/ha) at Van 84,6 kg/ha. The number of cracked fruits due to fallen rains during harvest was relatively high in Van and Bing (39,8 - 47,4%), while in the Germersdorf cultivar it was lower - 21,2%.

Propagation Material

Viral diseases in viticulture lead to annual losses in the quantity and quality of grape production. Since no direct control measures are available in practice, preventive measures are taken to keep the vines healthy. These include, for example, the testing of propagation material for viruses such as Arabis mosaic virus (ArMV), Grapevine fanleaf virus (GFLV) or Grapevine leafroll-associated virus 1 (GLRaV-1) and 3 (GLRaV-3). As long-term investigations have shown, GLRaV-1 (2.1%) occurs most frequently in southwestern German wine-growing regions, whereas GLRaV-3 (<0.1%) is almost never found. However, tests conducted over 12 years indicate that there is no general decline in virus-infected planting material. Thus, it can be assumed that a spread of the viruses via corresponding vectors still takes place unhindered. Beyond the examinations regulated within the German Wine Growing Ordinance, one-time tests were carried out on Grapevine Pinot gris virus (GPGV). This analysis showed that GPGV was found in 17.2% of the samples.

Main Determinants

Fruit quality is certainly influenced by biotic and abiotic factors, and a main quality attribute is the external appearance of the fruit. Various possible agronomical approaches are able to regulate the fruit microenvironment and, consequently, improve fruit quality and market value. Among these, fruit bagging has recently become an integral part of fruits’ domestic and export markets in countries such as Japan, China, Korea Australia and the USA because it is a safe and eco-friendly technique to protect fruits from multiple stresses, preserving or improving the overall quality. Despite increasing global importance, the development of suitable bagging materials and, above all, their use in the field is quite laborious, so that serious efforts are required to enhance and standardize bagging material according to the need of the crops/fruits. This review provides information about the effects of bagging technique on the fruit aspect and texture, which are the main determinants of consumer choice.

Analysis of the main trends in the development of the market for higher education services, affecting the transformation of university financing models, shows that improving the quality of educational services in Russian universities directly depends on an increase in the share of revenues received from research and development, as well as the ability of universities to present the results of their research and development in the form of a complete product from a marketing point of view and build a competent strategy for promoting innovations in the market. In the context of creating a long-term strategy for increasing the competitive advantages of leading universities, the author pays special attention to Project 5–100 of the Ministry of Education and Science of the Russian Federation, the purpose of which is to maximize the competitive position of a group of leading Russian universities in the global market of educational services and research programs. It is noted that university funding comes from various sources, while budgetary revenues dominate the structure of income, and the reduction in budgetary provision significantly affects the financial condition of Russian universities. The author comes to the conclusion that the forms and mechanisms of financial management of universities and research organizations are not strictly regulated, they independently choose the sources of funding.

Pollen Quantity

Squash seeds yield and quality can be improved by proper population plant spacing and the pollen quantity, which influences the pollination quality and fertilization. Nine experiments were conducted as a factorial combination of three spacing between plants (0.8 x 0.3, 0.8 x 0.6 and 0.8 x 0.9 m), two quantities of pollen (50% of an anther and another entire one) and natural insect pollination. Seed and fruit production parameters, and seed quality were evaluated. A randomized complete block design, five replications, with ten plants per plot was adopted. Larger plant spacing increased the average number of mature fruits and seed yield per plant. Seed yield was directly proportional to the amount of pollen used during pollination. Higher amounts of pollen resulted in higher seed yield per area, but the plant spacing did not affect this characteristic. Manual pollination, using a whole anther, did not differ from natural pollination in relation to seed yield and quality.
