ABSTRACT.- Orange fruit are sensitive to develop chilling injury (CI) during postharvest storage. Symptoms are brown depressed areas in the flavedo that coalesce with time causing severe economic losses. Abscisic acid (ABA) is applied during preharvest in different crops to promote cold tolerance but its effect in citrus fruit remains unknown. The objective of this work was to study the effect of preharvest application of ABA in alleviating CI during cold storage (1.0 ± 0.5°C). ABA at 500 mg.L−1 was applied at three different maturity stages of ?W. Navel?, ?Valencia? and ?Salustiana? oranges. ABA reduced incidence and severity of CI in the three orange cultivars. This positive effect was cultivar-dependent, being more pronounced in ?W. Navel? and ?Valencia? compared to ?Salustiana?. ?Salustiana? presented the highest CI incidence (>80% of the fruit with symptoms after 9 weeks of storage) and ABA applications only delayed its appearance. CI incidence was reduced up to 61% in ?W. Navel? and 74% in ?Valencia? compared to untreated fruit, concomitantly to severity. Evaluation of fruit quality revealed that ABA application does not affect fruit colour firmness or maturity index. Preharvest applications of ABA in oranges alleviate CI during postharvest cold storage without affecting fruit quality.

ABSTRACT.
Two japonica rice genotypes, INIA Tacuarí and L2825CA, were analyzed for tolerance to low temperature during early vegetative growth. Effect on photosynthesis, energy dissipation, pigment content, xanthophyll-cycle pool conversion, hydrogen peroxide accumulation, oxidative damage and antioxidant enzyme activities were determined to better understand potential mechanisms for cold tolerance. Photoinhibition was measured using chlorophyll fluorescence and oxidative damage by lipid peroxidation and electrolyte leakage. Both genotypes were demonstrated to be cold tolerant which was consistent with their reduced levels of photoinhibition and oxidative damage compared with a cold-sensitive genotype during chilling stress. The strategy for cold tolerance differed between the two genotypes, and involved different mechanisms for disposal of excess energy. The presence of high lutein concentrations and the existence of active non-harmful energy dissipation processes through the xanthophyll cycle appeared to be responsible for chilling tolerance in INIA Tacuarí. On the other hand, increased cold tolerance of L2825CA relative to INIA Tacuarí was related to the higher constitutive superoxide dismutase (SOD, EC 1.15.1.1), ascorbate peroxidase (APX, EC 1.11.1.11) and catalase (CAT, EC 1.11.1.6). |
