“…The marker bpb-3382 (66.24 cM, 1H), bpb-9005 (67.88cM, 1H) and bpb-5334 (67.88cM, 1H) were located at less than 3 cM away from the MQTL D16 (69.4cM, 1H) on 1H. The candidate gene ELIP2 (Early Light-Inducible protein2) in barley is related to the regulation of chlorophyll concentration in thylakoids and the redox homeostasis under photooxidative stress and water deficit conditions [57,58]. The marker bpb-8779 (77.41 cM, 2H) was close to the MQTL D4, which was localized at 76.77 cM on 2H.…”

Tibetan wild barley has been identified to show large genetic variation and stress tolerance. A genome-wide association (GWA) analysis was performed to detect quantitative trait loci (QTLs) for drought tolerance using 777 Diversity Array Technology (DArT) markers and morphological and physiological traits of 166 Tibetan wild barley accessions in both hydroponic and pot experiments. Large genotypic variation for these traits was found; and population structure and kinship analysis identified three subpopulations among these barley genotypes. The average LD (linkage disequilibrium) decay distance was 5.16 cM, with the minimum on 6H (0.03 cM) and the maximum on 4H (23.48 cM). A total of 91 DArT markers were identified to be associated with drought tolerance-related traits, with 33, 26, 16, 1, 3, and 12 associations for morphological traits, H+K+-ATPase activity, antioxidant enzyme activities, malondialdehyde (MDA) content, soluble protein content, and potassium concentration, respectively. Furthermore, 7 and 24 putative candidate genes were identified based on the reference Meta-QTL map and by searching the Barleymap. The present study implicated that Tibetan annual wild barley from Qinghai–Tibet Plateau is rich in genetic variation for drought stress. The QTLs detected by genome-wide association analysis could be used in marker-assisting breeding for drought-tolerant barley genotypes and provide useful information for discovery and functional analysis of key genes in the future.

“…Addition of Melafen to medium also had positive effect on root formation but only one of five concentrations used, 10 −5 %. With barley (Hordeum vulgare L.), Osipenkova et al [16] showed that the height of seedlings treated with Melafen at concentrations of 0.5 × 10 −10 and 0.5 × 10 −8 M increased by approximately 10% and 20%, respectively, but at high concentrations (10 −5 and 10 −3 M), Melafen had no effect on the growth of seedlings. No significant differences in rooting percentage, root length and root number per shoot were observed on media supplemented with 10 −4 %, 10 −3 %, 10 −2 % Fumar compared with control.…”

Application of growth stimulators can be especially effective on plantlets in vitro of tree species which are usually worse rooted and adapted in comparison with annual plants. In our work we evaluate effects of natural (dihydroquercetin, Zircon) and synthetic growth stimulators (Melafen, Fumar, Epin-Extra) on rooting and acclimatization of common ash (Fraxinus excelsior L.) microplants. The 0.05%-0.2% Zircon and 10 −5 % Melafen enhanced in vitro rooting by 29%-37% and 31%, respectively. Melafen also stimulated root formation faster compared to control plants. The dihydroquercetin concentration of 0.01% increased rooting by 24% and root number per shoot by 1.8 times. In vitro plants rooted on media supplemented with Melafen, Fumar and Zircon demonstrated enhanced ability to adapt to non-sterile conditions and accelerated growth. Two months after planting to the greenhouse, plants rooted on 0.01% dihydroquercetin were 45% taller than the control. Weekly spraying of plantlets with 0.02% Epin-Extra containing 24-epibrassinolid stimulated growth of uniform plants with large leaves. The obtained results support the use of growth stimulators for application in clonal micropropagation of common ash both for large-scale production of planting stock and for conservation of rare and valuable genotypes.
