Abstract

Effect of Salicylic acid (SA) at (0, 1 and 2 mM) and Putrescine (P) at the same concentration were surveyed on self-life and fruit quality of Fragaria × ananassa 'Selva'. Fruits had stored at 2± 0.5°C and 85–95% RH for 14 days. Some traits such as fruit rot; overall quality and marketability, pH, titratable acidity (TA), total soluble solids (TSS), ascorbic acid content, total anti-oxidant activity and total phenolics were evaluated after storage. Both SA and P application, separately or connectively, decreased fruit rot and significantly maintained fruit quality after end of storage period. Application of SA in 1, 2 (mM), P in 1(mM), and also SA in 1(mM) + P in 2(mM) had the most effect on it. Usage of SA and P significantly affected fruit quality and maintained pH and TSS, TA, vitamin-C and total anti-oxidant activity too. These results show that SA and P influences on fruit quality have been marked.
