Studies were carried out to observe the effect of sodium nitroprusside (SNP) treatment (source of nitric oxide) on chilling injury, electrolyte leakage, malondialdehyde (MDA) content, phenylalanine ammonia lyase (PAL) and pectin methyl esterase (PME) activities during low temperature storage of Japanese plums cv. ‘Santa Rosa’. All SNP treatments significantly alleviated CI symptoms during entire period of cold storage. Among different treatments, fruits treated with SNP (0.5 mM) showed 71% lower incidence of CI than control. Minimum electrolyte leakage (49%), PAL (53.6 μmoles of cinnamic acid produced min−1 g−1FW) and PME activity (0.36 μmol min−1 g−1FW) were observed in 0.5 mM SNP treated plums and the maximum in control. The maximum retention of ascorbic acid (25.6 mg/100 g pulp) and antioxidant capacity (14.7 μmol Trolox gâ^’1) was also exhibited by 0.5 mM SNP treated plums. Lowest MDA content (8.17 nmol gâ^’1 FW) and anthocyanin content (592.7 mg/kg FW) were also found in the fruits treated with 0.5 mM SNP. Thus, it can be concluded that SNP is an easy method for application of nitric oxide to maintain fruit quality and extending shelf life by inhibiting fruit softening through interfering with PAL and PME activities during cold storage of â€~Santa Rosa’ plums.

Santa Rosa plum (Prunus salicina Lindell) grows profitably under sub-temperate conditions of India but has a very limited postharvest life due to decay, mechanical injury and other ripening related changes. This necessitates searching for novel methods to make it available for longer period in the market. The plums were treated with salicylic acid (SA) (0.5, 1.0, 1.5 and 2.0 mM) aqueous dip treatments for 10 min at 20oC, air-dried and packed in plastic punnets followed by storage at 2ºC and 90 ± 5 % RH. Among different treatments, SA (2.0 mM) was found to be the best for maintaining the fruit quality and overall acceptability. Likewise, SA treatments significantly influenced fruit quality. The colour of SA treated fruits was maintained for a significant period over control. This study reflects that salicylic acid dip treatment can be integrated as an effective postharvest practice in the supply chain management of Santa Rosa plums to extend their storage life while maintaining fruit quality during storage for 36 days.

Studies were conducted to observe the effect of nitric oxide (NO) on â€~Santa Rosa’ plum, a Japanese plum grown extensively in India. â€~Santa Rosa’ plums were dipped in solution of sodium nitroprusside (SNP @ 0.25, 0.5, 1.0 and 1.5 mM) and distilled water (control) for 5 min. After treatment, fruits were air dried under fan and stored at 2°C temperature and 90 ± 5% RH for 36 days. Results revealed that SNP treatments significantly delayed the weight loss, fruit softening, and fruit decay in plums. However, minimum weight loss (8.3%), maximum firmness (3.463 N) and lowest fruit decay (0.0%) were recorded in SNP (0.5 mM) treated plums, whereas untreated fruits showed maximum weight loss (13.8%), lowest fruit firmness (1.595 N) and highest decay loss (18%). All SNP treatments significantly suppressed and delayed the rates of respiration and ethylene production by the fruits. Maximum phenolics content (106 mg/100 g pulp) and titratable acidity (1.1%) was observed in SNP @ 0.5 mM treated fruits, while it was lowest (65.3 mg/100 g pulp, 0.8% respectively) in untreated plums. Untreated fruits reached the highest SSC content on 16 day of storage (16.7°Brix) followed by a decline, while SNP (0.5 mM) treated fruits showed slower increase in SSC content. Hence, SNP 0.5 mM treatment can be effectively used for maintenance of desired postharvest quality and extending the market life of ‘Santa Rosa’ plums up to 36 days when stored at 2°C.
