Shabanov R. Biological substantiation of the most important elements of growing technology of coriander seeds of Nectar variety in the Crimea

Object: technologies of production of raw material and seminal goods of essential oils' plants. Aim: establishment of optimum criteria of major elements of technology of growing of high-quality sowing material of coriander. Methods: field, laboratory, statistical. Novelty: the chart of ontogenesis' periods of coriander has been developed. Peculiarities of plants' development under autumnal and spring terms of sowing have been established, the factors of plants' resistance to cold have been determined. The optimum modes of the use of Emistim growth factor while growing the coriander have been developed. The limits of humidity of fruits at which the accumulation of matter in seeds is completed are set. The new parameter of estimation of quality of sowing material - "Index of germination of seeds" has been developed. Results: the optimum autumn (on September 1st-20th) and early spring terms of sowing have been set, and also rational modes of harvesting of seeds have been determined (mowing at humidity of fruits 40-30% with the subsequent threshing at speed of drum rotation of 350-400 rotations/min.). Optimum doses and terms of the use of Emistim growth factor have been found (10 ml/ha in the phase of budding). Duration of afterripening of seeds (2-3 months) is set and for autumn sowing is recommended to use the seeds of past years of harvest. Application stage: the developed elements of growing technology of coriander seeds have been introduced at the farms in AR of Crimea and Khmel'nitskiy region at the area of 369,7 ha. Recommendations "Use of regulators of growth at growing of seeds of essential oils' plants" (Kyiv, 2004, 2008) have been published and passed for introduction in Ukraine. The results of researches are being used in educational process at preparation of Masters and Specialists of directions "Agronomy" and "Landscape architecture". Application area: seed growing farms.
