Abstract

This experiment was conducted to evaluate the effects of hydro-priming durations on some physiological traits and yield of safflower (Carthamus tinctorius L.) under different irrigation treatments. The results indicated that leaf water content (LWC), membrane stability index (MSI), chlorophyll content index (CCI), maximum quantum yield of the PSII (Fv/Fm), grain yield, oil percentage and yield decreased, but leaf temperature (LT) increased with increasing water stress. LT declined, but LWC, CCI, grain yield, oil percentage and yield enhanced as a result of hydro-priming treatments. Hydro-priming had no significant effect on MSI and Fv/Fm.
