“…Significant correlations between field emergence and laboratory tests of vigor have been published [18,19,20]. Higher precipitation shortly before the harvest decreased the seed vigor of spring barley significantly [21,22]. Higher air temperatures during this period and during the period April-July increased vigor significantly.…”

Abiotic and Biotic Stress in Plants - Recent Advances and Future Perspectives

Crop production, research of crop productivity, tolerance to abiotic and biotic stresses, plant disease, and pests all represent the problem of plant integrity. Plants represent an integrated system of units, which are responsible for its resistance to adverse environmental conditions on the basis of the evaluation of characteristics both aboveground and in the roots. This "complete unit" root and shoot has an influence on the formation of seeds, the quality of which may affect subsequent growth, development, and stress tolerance of the filial generation. Properties of the roots predominantly influence especially at drought stress conditions growth, development, and the metabolic processes in the aboveground part of the plant. The seed traits affect the filial generation root morphology at the beginning of the vegetation period especially length, surface, depth of root penetration, and also root weight . In the biology of the seeds, roots, yield formation, stress tolerance, etc., attention needs to be paid to plant integrity and adaptability during variable environmental conditions. Every plant, and its traits, is a result of all the plant's activities. This is important for plant breeding. For example, it is possible to provide selection for cultivar traits at seed germination. Quality of the embryonic traits is important for subsequent growth and development. In the juvenile phase, and in later stages, the same genotype is still active. This is is among the main reasons for studying plant integrity.

“…e rate of quality deterioration also depends on the differences in the genetic backgrounds of the varieties. e relative contributions of the variety to the total variation have been reported to be higher for vigour than for germination [19,20]. Cereal grains with poor dormancy at harvest are susceptible to preharvest sprouting damage, while long-lasting dormancy can impede activities that depend on rapid germination, such as malting or the emergence of a uniform crop [21].…”

To ensure production of quality malt that conforms to brewing requirements, the barley used should have minimal postharvest dormancy and be able to germinate rapidly and uniformly. The objective of the study was to compare the changes in seed germination, vigour trends, and storage stability of two-row Zimbabwean commercially grown malting barley varieties (Hope and Sierra), as the postharvest storage time increased. The two varieties were stored for 12 months, and at monthly intervals, germination index, capacity, and energy were determined. In addition, other quality parameters (protein content, screening, moisture content, water sensitivity, and insect damage index) were also assessed. Hope’s germination index improved with an increase in storage time from 8.67 at the beginning of the study to 9.18 at the end of the study, while that for Sierra diminished with storage from 9.35 to 6.71. Generally, water sensitivity improved with postharvest storage for both varieties. However, the germination energy for Hope diminished with increased postharvest storage compared to Sierra. Hope variety is the more suitable variety for extended postharvest storage than Sierra. However, Sierra variety is more suitable for early malting postharvest storage.

“…A number of research scientists claim that the growth rate of cereal crops can be judged from coleoptile length, first leaf and germinal roots. These traits are affected by genotype, climatic characteristics of the year, applied agrotechnics, as well as the growing conditions and duration of seed storage (Pieta Filho, C., Ellis, R. H.,1991;Box, A. J., Jefferies, S. P., Barr, A. R., 1999;Maleki Farahani et al, 2010;Vulchev et al, 2010;Bodner et al, 2013;Tabatabaei, S. A., 2015).…”

In the period 2018-2020 in the Institute of Agriculture -Karnobat, Bulgaria the influence of growing conditions on the growth activity of winter barley genotypes was studied. The experiments were performed in field and laboratory experiments. In a field multifactorial experiment with 4 fertilization variants (N0: N8: N12: N16) and three sowing rates (250, 350 and 450 germinating seeds) the barley varieties Kuber, Sayra, Zemela and Bozhin were grown. The obtained seeds from the different variants were studied in a laboratory experiment by the method of rolls. From each variant 20 seeds are laid in 3 repetitions on filter paper. The rolls are immersed in water and after 10 days the length of the first leaf, the length of the coleoptile, the number of roots and their length are taken into account. It was found that there are proven differences in the indicators in the studied genotypes. On average for the years of study, the length of the first leaf and the length of the roots is the largest for the seeds obtained in the variant at a sowing rate of 450 germinating seeds and N8. With the largest length of coleoptile and the largest number of roots are the seeds of the variant with a sowing rate of 250 germinating seeds and N8. Analysis of the variant shows that the length of the first leaf, the coleoptile and the number of roots depend on the genotype. The strongest influence on the length of the roots have the conditions of the year. The interaction between the two factors strongly influences all the studied indicators. The interaction between the year, genotype, sowing rate and fertilization also has a great influence on the indicators of the length of the first leaf, coleoptile and roots.
