Effect of Salicylic Acid, Benzoic Acid, and p-Coumaric Acid on Growth, Chlorophyll, Proline, and Vitamin C of Salinity-Stressed Tobacco (Nicotiana tabacum)

Photoelectron-photofragment coincidence spectroscopy was used to study the dissociation dynamics of the conjugate bases of benzoic acid and p-coumaric acid. Upon photodetachment at 266 nm (4:66 eV) both aromatic carboxylates...

Disk Method

Strawberries are an extremely perishable fruit mainly due to their soft texture and sensitivity to fungal infection. Postharvest application of conventional fungicides to fruits is prohibited. As an alternative to fungicides, salicylic acid has been found to enhance disease resistance of horticultural crops. In order to study the effect of salicylic acid as a phenolic compound on the postharvest durability and quality characteristics of strawberry fruit. ‘Gaviota’ strawberries were treated with SA at different concentrations (0, 25, 50 and 100 µlL-1), then stored for 12 days at 4 ˚C and 75 % RH in darkness. Two different methods were applied (spray SA on fruits and paper disk method). Quality attributes such as weight loss, pH, TA, TSS, vitamin C, anthocyanin, calcium, pectin, CAT, POD, PG activity, decay percentage and sensory analyses evaluated every 3 days during storage. Results showed that, treated fruits with SA had lower weight loss, pH, TSS, POD, PG, decay and higher TA, vitamin C, anthocyanin, calcium, pectin, CAT and fruit quality compared with controls. Between two methods of treatment, paper disk method had higher effect on fruit decay and quality compared to spray method and as a general result, caused longer storability.

Adductor Muscles

The action of the following compounds on homogenates of the adductor muscles of Saxostrea commercialis was studied: urethane, phenyl urethane, chloral hydrate, salicylic acid, morphine, caffeine, barbitone, benzoic acid, salicylamide and benzamide.It was found that, except for 0·05 M urethane, the endogenous oxygen consumption was reduced by all these compounds when present in concentrations ranging from o·001 to 0·05M. The oxidation of succinic acid was partially inhibited by these substances.These findings are discussed in relation to similar studies on other tissues.
