| description | Dormancy of barley belongs today to the parameters of malting barley quality evaluation. Intensity of barley dormancy was checked by determination of germination energy on Petri dishes with 4 ml of water after 72 hours in a thermostat at 20 °C. Germination rate was determined by the calculation from the data of germination energy pursuant to the previously published formula. Determination of germination energy of malting barley was done in 2001 to 2003 always 6 weeks after harvest. The following malting barley varieties were assessed - Jersey, Kompakt, Prestige, Scarlett, and Tolar, they are the principal malting varieties. Samples were selected based on the following quality parameters: protein content in barley is from 10 to 12 % in dry matter and germination capacity of barley is higher than 96 %. It was demonstrated that the number of forecrops after which barley is grown, was significantly increased. It was confirmed that dormancy of barley was mostly influenced by year, differences among varieties were small. Tuber crops were the best forecrop (forecrop with the best germination energy), there is not a statistically significant difference between oil crops and cereals. It was demonstrated that use of calculation of germination rate from the data of germination energy would enable to distinguish the effect of individual factors more explicitly. The presented results were acquired in the framework of the solution of the research project NAZV, reg. no. QC 1096 "Research on Factors of Optimation of Cereal Production Quality in the CR" which was solved in 2001-2004.Dormancy of barley belongs today to the parameters of malting barley quality evaluation.
