“…Germination rate, coleoptile length, shoot length, root length, shoot fresh and dry weight, root fresh and dry weight were measured on the 14th day of priming treatment with essential oils ( Zencirci et al, 2019 ). Relative water content (RWC) was determined by drying the leaf sample at 105 °C for 30 min and then at 70 °C until a constant weight was reached.…”

Drought is one of the major constraints to global crop production. A number of sustainable systems have focused on the development of environmentally friendly innovative biotechnological interventions to prevent yield losses. The use of essential oils as a seed priming agent can make an important contribution as a natural stimulant in increasing drought stress tolerance. This study focuses on the effects of seeds coated with different doses (D0 (0%), D1 (0.01%), D2 (0.05%), D3 (0.10%) and D4 (0.25%)) of sage, rosemary and lavender essential oils on wheat germination, seedling establishment and yield parameters. Turkey’s local wheat genotype Köse was used as plant material. The impact of the seed priming on germination rate, coleoptile length, shoot length, root length, shoot fresh and dry weight, root fresh and dry weight, relative water content (RWC), proline, and chlorophyll contents was assessed in laboratory experiments. In addition, the effect of essential oil types on yield parameters and agronomic components (plant height, spike height, number of grains per spike, grain yield per spike, grain yield per unit area, thousand-grain weight) was evaluated in a field experiment during the 2019–2020 crop seasons in a semi-arid climate. According to laboratory results, the highest germination rate among all treatment doses was determined in the D2 treatment (rosemary 93.30%, sage 94.00% and lavender 92.50%), while the lowest germination rates for all essential oil types were determined in the D4 treatment (rosemary 41.70%, sage 40.90% and lavender 40.90%). Increasing treatment doses showed a similar suppressive effect on the other parameters. In the field experiment, the highest grain yield (256.52 kg/da) and thousand-grain weight (43.30 g) were determined in the rosemary treatment. However, the priming treatment has an insignificant on the number of grains per spike and the spike length. The light of these results, the effects of essential oil types and doses on yield parameters were discussed. The findings highlight the importance of using essential oils in seed priming methods for sustainable agricultural practices.

“…Наименьшими коэффициентами влагоотдачи на единицу площади листа (К1) характеризовались образцы T. monococcum UA0300113 (Сирия) и UA0300282 (Венгрия), у которых они составляли для второго и флагового листьев соответственно, (мг/см 2 ) 10.9, 7.0 и 11. 4 В то же время наблюдается отрицательная средняя корреляция коэффициента влагоотдачи c площадью и длиной флагового листа (r= -0.490 и -0.657 соответственно) (p<0,05), слабая тенденция к отрицательной связи коэффициента влагоотдачи c площадью и длиной второго листа (r-0,127 и -0,160 соответственно) (p>0,05). Следовательно, с увеличением размеров листа наблюдается тенденция к уменьшению влагоотдачи на единицу площади листа.…”

“…Возрастание интереса к этой культуре у потребителей и агрономов обусловливает необходимость повышения ее урожайности, которая на территории Украины в большой степени определяется устойчивостью к засухе. Исследованиями показана значительная дифференциация однозернянок по засухоустойчивости [2,3], причем часть генотипов не уступают полиплоидным пшеницам, в том числе мягкой [4]. Наибольший интерес представляют сорта, засухоустойчивость которых обусловлена устойчивостью их тканей к обезвоживанию, более эффективному использованию влаги для образования надземной биомассы и хозяйственной ее части [5].…”

“…В связи с этим водоудерживающую способность (в сочетании с параметрами органов растения) целесообразно использовать для фенотипирования представителей четырех видов однозернянки, которое служит основой последующего генотипирования с выявлением генетических маркеров интересующих признаков. Показана эффективность использования многомерного анализа для этих целей [4].…”

Aim. On the basis of multivariate analysis, to differentiate einkorn wheat accessions by the water-holding capacity of leaves and ears and the parameters of these organs at the level of species and genotypes. Methods. The water-holding capacity was assessed by the moisture-yielding coefficient which was determined by the method of N.N. Kozhushko (Kozhushko, 1988). Differentiation of einkorn samples was carried out by the method of principal components in the interpretation of A.V. Korosov (Korosov, 1996). Results. Triticum monococcum UA0300113, Syria, and UA0300282, Hungary were characterized by the lowest specific moisture-yielding coefficients: for the second and flag leaves, respectively, (mg / cm2) 10.9, 7.0 and 11.4, 10.7; ears – the same samples as well as Triticum boeoticum UA0300401, Ukraine-Crimea: (mg / cm) 29.6, 28.2, 25.4. With an increase in the size of the lamina, there is a tendency to a decrease in its specific moisture yield. The samples of eincorn are differentiated into 4 clusters corresponding to the species. Conclusions. T. monococcum UA0300113, Syria, and UA0300282, Hungary are relatively drought tolerant. The complex of features characterizing leaf and spike size in combination with the moisture-yielding coefficients processed by the method of principal components makes it possible to differentiate einkorn oaccessions by species and genotype. Keywords: einkorns, moisture yield, drought resistance, leaf, ear.

“…A dendrogram was constructed according to the genetic distance values by using the unweighted pair group method with the arithmetic mean method. Triticum aestivum and Triticum monococcum populations are clustered into different clusters (Zencirci et al 2019). The number of sub-populations was identified as the optimal value for K = 7.…”

The aim of this study is to investigate genetic diversity in 48 einkorn (Triticum monococcum L. ssp. monococcum) landraces grown in agricultural areas of Bolu and Kastamonu. Therefore, variation in seven agro-morphological traits was investigated. Agro-morphological traits such as leaf weight (mg), coleoptile length (cm), root number (n), root length (cm), fresh root weight (mg), and dry root weight (mg) were examined by the coefficient of variation, ANOVA, and principal components analysis. The highest coefficient of variation (%) was observed in fresh root weight (FRW = 52.09%), while the lowest was in leaf weight (LW = 8.9%). Principal Component Analysis (PCA) was calculated as 76.93% variation in two main components. For molecular characterization, data obtained with iSSR primers were analyzed with the population genetics analysis program PopGene (ver. 1.32). According to PopGene results, the mean number of alleles, the mean number of effective alleles, and average genetic diversity values were calculated as na = 2, nea = 1.33, and h = 0.13, respectively. Among the agro-morphological traits, germination power, root number, and coleoptile length appeared to be reliable traits. The results show that the use of morphological characters alone for genetic diversity in populations is not sufficient to determine the difference between populations and their genetic structure.
