Specific vegetable seeds germination of umbelliferae cultures at different temperatures

The effect of temperature during seeds germination of some species of Umbelliferae vegetable crops has been studied. There is a different reaction of vegetable crops on the temperature factor: depending on crops and temperature, the number of days until the maximum rate of growth can varied from 7,6 to 22,8 days, and percentage of germinated seeds can varied from 7% to 88%. The effect of temperature on growth of seeds embryo has been studied in different crops. The «degree of underdevelopment of embryo» (DUE) characterized the morphological and anatomical features of embryo varied from 13 to 52%. The temperature coefficient (Q 10) for the rate of germination of seeds of vegetable crops of Umbelliferae was 1,23 - 1,82.
