Grain Zn Concentration

Human zinc (Zn) deficiency is a worldwide problem, especially in developing countries due to the prevalence of cereals in the diet. Among different alleviation strategies, genetic Zn biofortification is considered a sustainable approach. However, it may depend on Zn availability from soils. We grew Zincol-16 (genetically-Zn-biofortified wheat) and Faisalabad-08 (widely grown standard wheat) in pots with (8 mg kg−1) or without Zn application. The cultivars were grown in a low-Zn calcareous soil. The grain yield of both cultivars was significantly (P≤0.05) increased with that without Zn application. As compared to Faisalabad-08, Zincol-16 had 23 and 41% more grain Zn concentration respectively at control and applied rate of Zn. Faisalabad-08 accumulated about 18% more grain Zn concentration with Zn than Zincol-16 without Zn application. A near target level of grain Zn concentration (36 mg kg−1) was achieved in Zincol-16 only with Zn fertilisation. Over all, the findings clearly signify the importance of agronomic Zn biofortification of genetically Zn-biofortified wheat grown on a low-Zn calcareous soil.

The article highlights the results of research carried out in 2019-2020 to study the reasons for the drying out of the stems of black currant (Ribes nigrum L.), red currant (Ribes rubrum L.) and golden currant (Ribes aureum L.). As a result of research, the fungus Sphaeropsis malorum Peck. in the first in Russia it was revealed from the drying stems of three types of black currants, red currants and golden currants. This  pathogen inhabited currant stems together with fungi from the genus Cytospora spp., causative agents of stem drying. On red currants, it was established that S. malorum was the main causative agent of branch drying, as indicated by the high frequency of occurrence (75.0-83.3 %) of this fungus on the affected stems, compared with species from the genus Cytospora spp. (16.7-33.3 %) and Phomopsis ribesia (25.0 %). Due to the fact that the cultivation of currants in the immediate vicinity of apple and pear trees leads to infection of plants with the fungus S. malorum, it is necessary to avoid planting currants in the vicinity of fruit-bearing seed gardens.
