“…The cause for the decrease in the combinations with low plant survival ratio, which was found to reduce the growth and development of fruit trees from year to year, can be linked to the age of the trees. However, according to Mauro et al (2022), weak connection and formation of vascular system after some years led to abnormal and restricted growth of fruit trees, and graft incompatibility may be the reason for the decrease in plant survival ratio when the pear is grafted on quince. When closely related species or cultivars are grafted onto each other, the survival rate increases, while the survival ratio in distant relatives decreases.…”

“…Apart from the compatibility or incompatibility between rootstock and scion, the survival rate depends on the resistance to climatic conditions of the rootstock (Lepsis et al, 2013), pest and disease (Hudina et al, 2014;Shaltiel, 2018;Habibi et al, 2022), soil conditions and salinity (Okubo and Sakuratani, 2000). Grafted fruit trees with good graft compatibility and the ability to form a vascular system will survive for many years and continue their normal lives without any restrictions (Mauro et al, 2022). Quince rootstocks had a lower survival ratio than pear rootstocks with lower graft incompatibility, and different rootstock and cultivar combinations had significantly different survival ratios (Ozturk, 2021a).…”

“…Stone fruit rootstocks are important in increasing the productivity of grafted cultivars. They are broadly utilized because of their special capabilities to control tree size, orchard uniformity, resistance to stress factors that affect the scion cultivar, quantity, and quality of fruits [17]. The root system is quite winter-hardy and does not form root shoots in the garden [27].…”

Background: The cultivation of stone fruits is of primary importance in Armenia. Their fruits contain antioxidants, fiber, potassium, vitamin A, C, E, minerals, etc., which have a beneficial effect on human health and prevent many diseases. The concentration of those components varies depending on ecological factors, cultivar, rootstock, cultural practices, etc. Clonal rootstocks are important for increasing orchard density, tree uniformity, and high yields, and they can also affect fruit quality. In vitro culture is a valuable method for rapid propagation of high-quality, virus free plant material. Objective: The purpose of this study was to develop in vitro production technology for the stone-fruit rootstock cultivar Evrica 99, and to determine if rootstocks affect some fresh fruit traits of ´Yerevani´ and ´Sateni´ apricot cultivars. Methods: The shoot apical meristem and lateral bud served as explants for shoot regeneration. Different sterilizing agents at various periods of exposure were used for the explant surface sterilization. Various concentrations of phytohormones, both individually and in combinations, were employed for in vitro regeneration and rooting of plants. The titratable acidity (TA), dry matter (DM), vitamin C, mineral content, total carotenoids (TC), and sugar contents were evaluated in fresh fruit. Results: The most optimal option for explant surface sterilization was the gradual application of calcium hypochlorite [Ca (ClO)2] (2.0% solution, exposure time 10 min) and ethanol (70% solution, exposure time 20 s), as a result of which we had 75.5% survival rate of explants. The efficient medium for in vitro shoot regeneration was MS supplemented with 6-Benzylaminopurine (BAP) 0.8 mg/l, Kinetin (Kin) 0.2 mg/l, and Gibberellic acid (GA3) 1.0 mg/l. The half-strength Murashige and Skoog (MS) medium containing 0.8 mg/l indole-3-butyric acid (IBA) was optimal for in vitro rooting. Rooted plants were successfully adapted with a survival rate of 85.0%. The defined method can be successfully used for 'Evrica 99' cultivar micropropagation. The results obtained showed that fruit quality strongly depended on both the varieties and the rootstock tested. Conclusion: In the current study, an alternative in vitro propagation technology for rootstock cultivar ´ Evrica 99 was developed by direct organogenesis, enabling mass-scale production of virus-free plants that is suitable for commercial purposes as well. The apricot cultivars ´Yerevani´ and ´Sateni´ grafted on the virus-free rootstock cultivar Evrica 99 showed higher fruit quality traits, which are essential for human health and diet.

“…This often results in reduced germination rates, slower growth, decreased plant height, and leaf wilting ( Hao et al, 2021 ). High Na + concentrations in saline-alkali soils cause osmotic stress, obstructing the absorption of water and nutrients, leading to a nutrient-water imbalance ( Mauro et al, 2022 ). Potassium (K + ) is a key cation in plant cells, improving plant resilience to both abiotic stresses, such as salt, drought, and heavy metals, and biotic stresses like fungi ( Leigh and Jones, 1984 ; Amtmann et al, 2008 ).…”

Introduction: Soil salinization poses a significant challenge to plant growth and vitality. Plants like Tamarix ramosissima Ledeb (T. ramosissima), which are halophytes, are often integrated into planting schemes tailored for saline environments. Yet, the role of WRKY transcription factors in T. ramosissima, especially under sodium chloride (NaCl) stress mitigated by exogenous K+ application, is not well-understood. This research endeavors to bridge this knowledge gap.Methods: Using Pfam protein domain prediction and physicochemical property analysis, we delved into the WRKY genes in T. ramosissima roots that are implicated in counteracting NaCl stress when aided by exogenous K+ applications. By observing shifts in the expression levels of WRKY genes annotated to the KEGG pathway under NaCl stress at 0, 48, and 168 h, we aimed to identify potential key WRKY genes.Results: We found that the expression of 56 WRKY genes in T. ramosissima roots responded to exogenous K+ application during NaCl stress at the indicated time points. Particularly, the expression levels of these genes were primarily upregulated within 168 h. From these, 10 WRKY genes were found to be relevant in the KEGG pathways. Moreover, six genes, namely Unigene0024962, Unigene0024963, Unigene0010090, Unigene0007135, Unigene0070215, and Unigene0077293, were annotated to the Plant-pathogen interaction pathway or the MAPK signaling pathway in plants. These genes exhibited dynamic expression regulation at 48 h with the application of exogenous K+ under NaCl stress.Discussion: Our research highlights that WRKY transcription factors can modulate the activation or inhibition of related genes during NaCl stress with the application of exogenous K+. This regulation enhances the plant’s adaptability to saline environments and mitigates the damage induced by NaCl. These findings provide valuable gene resources for future salt-tolerant Tamarix breeding and expand our understanding of the molecular mechanisms of WRKY transcription factors in alleviating NaCl toxicity.
