Abstract
This study evaluated the effects of sodium nitrophenolate (SNP) and N-Acetyl-Thiazolidine-4-carboxylic acid (AATC) treatments on leaf morphology and chlorophyll content in date palm (Phoenix dactylifera L., Barhi cv.) over an 18-month period. Seven treatments, including varying concentrations of SNP (0.1, 1, and 10 ppm) and AATC (0.1, 1, and 10 ppm), were assessed alongside a control. Results demonstrated significant improvements in leaf length, width, and chlorophyll content, with distinct dose-response relationships. SNP 10 ppm exhibited the highest mean leaf length, representing a 371% increase over control, while SNP 0.1 ppm and AATC 0.1 ppm produced the greatest enhancements in leaf width, respectively and chlorophyll content. AATC treatments showed an inverse dose-response for width and chlorophyll accumulation, indicating potential over-inhibition of ethylene at higher concentrations. Overall, both compounds elicited rapid and sustained morphological improvements, underscoring their value in enhancing vegetative growth and photosynthetic capacity. These findings support the strategic use of SNP and AATC in sustainable date palm cultivation to promote early vigor and long-term productivity
