The article presents results of the study of influence of biochemicalcomposition of cloves and temperature on the growth of garlic plants. Correlationanalysis showed a weak and average dependence of the length of the plantregrowth period on the biochemical composition of garlic cloves. It was determinedthat the main factor affecting the timing of plant emergence is temperature. Bythe duration of the period from planting to germination, varieties andpromising samples of garlic of ARRRI breeding were divided into threegroups.The emergence of seedlings in the first group is marked on the seventhday after planting. At the same time, the sum of air temperatures should be66.5 ° C and the soil at a depth of 5 cm – 59.0 °C. Seedlings from the second group appeared on thefifteenth day. The sum of air temperatures is 132.8 °C and soil – 130.9 °C. Thethird group has the longest regrowth period – 25 days. For the emergence ofgarlic shoots, a sum of temperatures is necessary – 200 °C, the same amount ofheat is necessary for the growth of mother plants of onions of wintervarieties.When determining the timing of planting winter garlic in the field,you should consider the weather forecast and begin planting with varieties ofthe third group, ending with the first group of garlic varieties, so that bythe onset of a steady cold snap, the root system of the garlic plants hasdeveloped without regrowth of leaves on the soil surface.When using plantingmaterial for the forcing of garlic on green varieties are also divided into twogroups according to the length of the period from planting to germination. Itwas established that in the first group of varieties shoots appeared on the17th day after planting. For them, the sum of air temperatures is 106.4 °C. Theshoots of the second group appeared on the 25th day, after planting and the sumof air temperatures was 141.0 °C.
