Solution uptake: According to the results shown in Table 2, using SA and PUT as a preservative
significantly increased the vase life (P≤5%). the most water uptake (2.52 g stem-1 day-1) was observed in
100 mg l-1 SA sevennth and Ninth day of the experiment. The effectiveness of this compound can be due
to water relations enhancement, prevent vascular occlusion due to antimicrobial effect, anti-ethylene
effect which reduces respiration rate of cut flowers and increased dry matter percent (Edrisi, 2009; Gast
Karen, 1997). Zamani et al., (2011) reported that 1.5 mM salicylic acid (SA) increased water uptake about
13 ml compared to the control in cut chrysanthemum (Chrysanthemum morifolium L.).
