Abstract. The article presents results of the study of influence of biochemical composition of cloves and temperature on the growth of garlic plants. Correlation analysis showed a weak and average dependence of the length of the plant regrowth period on the biochemical composition of garlic cloves. It was determined that the main factor affecting the timing of plant emergence is temperature. By the duration of the period from planting to germination, varieties and promising samples of garlic of ARRRI breeding were divided into three groups.The emergence of seedlings in the first group is marked on the seventh day after planting. At the same time, the sum of air temperatures should be 66.5 ° C and the soil at a depth of 5 cm – 59.0 °C. Seedlings from the second group appeared on the fifteenth day. The sum of air temperatures is 132.8 °C and soil – 130.9 °C. The third group has the longest regrowth period – 25 days. For the emergence of garlic shoots, a sum of temperatures is necessary – 200 °C, the same amount of heat is necessary for the growth of mother plants of onions of winter varieties.When determining the timing of planting winter garlic in the field, you should consider the weather forecast and begin planting with varieties of the third group, ending with the first group of garlic varieties, so that by the onset of a steady cold snap, the root system of the garlic plants has developed without regrowth of leaves on the soil surface.When using planting material for the forcing of garlic on green varieties are also divided into two groups according to the length of the period from planting to germination. It was established that in the first group of varieties shoots appeared on the 17th day after planting. For them, the sum of air temperatures is 106.4 °C. The shoots of the second group appeared on the 25th day, after planting and the sum of air temperatures was 141.0 °C.
