Salinity has severely affected agricultural productivity and the damaging effects of salt accumulation have influenced both ancient and modern civilizations. Morning glory spinach (Ipomoea aquatica L.) is the semi-aquatic plant that grows in water or damp soil but it rarely cultivates in salt stress, in this study, morning glory treated in salinity and salicylic acid also combined. Salicylic acid is a signaling molecule known to participate in defense responses against variety of environmental stress including salinity. The objective of this study was to evaluated the performance of morning glory seed treated with different concentrations of saicylic acid (0, 0.05, 0.1 and 0.3%) under 50, 100 and 150 mM NaCl. Morning glory showed reduced germination percentage, shoot and root length. In addition, α-amylase and phytic acid contents were decreased when increasing SA concentrations under 50 and 150 mM of NaCl. We found that SA could be improve low phytate contents but not stimulate germination and growth rate on spinach.
