“…Furthermore, the differences between Garnem and GF 677 were observed. Rootstock influences the scion and increases the plant tolerance against environmental stresses (Bolat et al, 2016;Polat, 2021). In the present study, two peach rootstocks were compared and VXW of GF 677 was found further compared to Garnem.…”

Water movement in xylem vessel presents hydraulic system. The hydraulic system may encounter embolism (cavitation) caused by environmental stresses. Tracer dyes are distributed within the xylem and can be monitored by sectioning the tissue called dye infusion technique. The current experiment determined the optimal conditions for acid fuchsin dye infusion technique to monitor the water-conducting pathways in shoots of sweet cherry and peach trees. Shoots from 18-year-old sweet cherry cultivar 0900 Ziraat grafted onto Gisela 5 and 2-year-old peach cultivar Rich May grafted onto Garnem and GF 677 were used in the experiment. Xylem functionality and xylem water flow velocity (VXW) were evaluated by dye infusion technique. The intensity of acid fuchsin staining in the shoots increased with dye concentration. In sweet cherry trees, VXW decreased with the time course and 120 mn had the lowest VXW value. In peach, VXW of GF 677 was found further compared to Garnem. The experiment showed that the dye infusion technique is reliable for the visualization of waterconduction pathways and xylem functionality. Furthermore, the technique can be used in the studies of bud dormancy break of trees and stresses.

“…The scenario of deficit irrigation is still under research for a few olive cultivars, such as 'Kalamata', which is classified as a drought-sensitive cultivar. Generally, drought mainly impacts plant morphology, physiology, and biochemistry [25]. Under such conditions, xylem vessels become susceptible to embolism or dysfunction, leading to lower hydraulic conductance and carbon intake, which in turn affect plant growth characteristics and productivity [26].…”

In Egypt’s arid and semi-arid lands where the main olive production zone is located, evapotranspiration is higher than rainfall during winter. Limited research has used nanomaterials, especially nano-silicon (nSi) to improve the growth, development, and productivity of drought-stressed fruit trees, amid the global water scarcity problem. To assess the role of nSi on drought-sensitive ‘Kalamata’ olive tree growth, and biochemical and physiological changes under drought conditions, a split-plot experiment was conducted in a randomized complete block design. The trees were foliar sprayed with nSi in the field using nine treatments (three replicates each) of 0, 150, and 200 mg.L−1 under different irrigation regimes (100, 90, and 80% irrigation water requirements ‘IWR’) during the 2020 and 2021 seasons. Drought negatively affected the trees, but both concentrations of nSi alleviated drought effects at reduced irrigation levels, compared to the non-stressed trees. Foliar spray of both concentrations of nSi at a moderate level (90% IWR) of drought resulted in improved yield and fruit weight and reduced fruit drop percentage, compared to 80% IWR. In addition, there were reduced levels of osmoprotectants such as proline, soluble sugars, and abscisic acid (ABA) with less membrane damage expressed as reduced levels of malondialdehyde (MDA), H2O2 and electrolyte leakage at 90% compared to 80% IWR. These results suggest that ‘Kalamata’ olive trees were severely stressed at 80% compared to 90% IWR, which was not surprising as it is classified as drought sensitive. Overall, the application of 200 mg.L−1 nSi was beneficial for the improvement of the mechanical resistance, growth, and productivity of moderately-stressed (90% IWR) ‘Kalamata’ olive trees under the Egyptian semi-arid conditions.

Winter Potato Water Footprint Response to Climate Change in Egypt

et al. 2022

The limited amount of freshwater is the most important challenge facing Egypt due to increasing population and climate change. The objective of this study was to investigate how climatic change affects the winter potato water footprint at the Nile Delta covering 10 governorates from 1990 to 2016. Winter potato evapotranspiration (ETC) was calculated based on daily climate variables of minimum temperature, maximum temperature, wind speed and relative humidity during the growing season (October–February). The Mann–Kendall test was applied to determine the trend of climatic variables, crop evapotranspiration and water footprint. The results showed that the highest precipitation values were registered in the northwest governorates (Alexandria followed by Kafr El-Sheikh). The potato water footprint decreased from 170 m3 ton−1 in 1990 to 120 m3 ton−1 in 2016. The blue-water footprint contributed more than 75% of the total; the remainder came from the green-water footprint. The findings from this research can help government and policy makers better understand the impact of climate change on potato crop yield and to enhance sustainable water management in Egypt’s major crop-producing regions to alleviate water scarcity.
