Mykhailyk S. The yield of tomatoes hybrids in the greenhouses in depending on seed growing conditions

The results of three-year investigations that confirmed influence of growing conditions of seed oncrop capacity of tomatoes hybrids in winter hydroponic greenhouses are shown. The rules of positive effect of these conditions on tomatoes yield and on elevation of bunch placing of tomatoes were determined. The influence of these conditions on method of hybridization and on quality of hybrid seeds of these tomatoes was researched too. There are determined that hybrid seeds of tomato plants for greenhouses have to be grown better in greenhouses heated with outline warm of soil and air. These growing conditions provided the highest yield of hybrid seeds Konsuelo F1 (19,3 g/m2) and Nezabudka F1 (16,6 g/m2) and its better quality and better sufficient economic benefit from its production. The crosses from the first to eighth bouquet and to mass collections of seeds get better results in hybrid seed grooving of tomatoes in a greenhouse heated soil and air. Better quality and higher yield of (in 1,6–1,7 times) hybrid tomato seeds were obtained by pollination of flowers on the next day after castration. The growing conditions and elongation of bunch placing of tomatoes and method of hybridization of tomatoes seeds do not influence on morphological special feature of seeds if they was be grown in hydroponic greenhouses. These special features depend from growing technology. The use of seeds from the mass gathering that grown in greenhouses if were used pollination of flowers on the next day after castration can get the higher yield of the tomatoes hybrids F1.
