Influence of methods of treatment on barbaris vulgaris seeds germination in conditions of Omsk region

Determined the ability of barberry seeds, which were matured in Omsk region, to germinate. According to research the viability of seeds is 86%, laboratory germination - 6%. Impact of variable temperatures using “Gradient table” increases germination to 60%. According to our observations barberry seeds germinate in a wide temperature range with high amplitude (till 14,4°C) and have germination 20-60%. When we have the constant temperature in the range of 18,5-20,1°C (range 0°C) germination reaches 40%. Maximum germination of barberry seeds was noted in the range of varying temperatures 12,1-23,3°C. The most effective temperature regime was established: 12,1-21,7, 15,3-23,3 and 18,5-21,7°C. The best results were marked with the amplitude of 8-9,6°C, about 60% seeds germinate.
