Determination of xylem water flow velocity of some Prunus shoots by dye infusion technique

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