"The presented work is based on laboratory testing of seed germination speed, emergence and seedling growth under different stress conditions simulated by subnormal water level, extreme high and low temperatures. It allows one to eliminate the plant materials (initial breeding materials and cultivars) which do not tolerate extreme temperatures and temperature changes during germination, have low water use efficiency and are intolerant to abiotic stresors all right at the seed level. It was confirmed that these genotypes also have poor field emergence and initial root growth implications for further vegetation periods, mainly for over wintering and spring regeneration which has significant influence on the yield. The method also represents the tool for screening genetic resources with the resistance to the abiotic stressors and this technology process is also acceptable for other crops. The results confirm the importance of the seed and root characteristics for crop production. The deteriorating quality of soil in recent years, increasing variability of weather and long periods of drought directly support the need to intensify activities in this research. Obtained results also show the influence of seed quality characteristics on roots and above ground parts of the plant. A relationship exists also vice versa."@en . . "P(QI91C123), P(QJ1310072)" . . .
