“…This would also explain the lack of effect in SA treated apples [67] and pears [66] inoculated with P. expansum 2 h after the treatment. In contrast, treatment with MeJA at 100-200 µmol l -1 significantly reduced lesion diameter even if pears were inoculated with P. expansum only 2 h after the treatment [46], which is consistent with the view that defence responses against necrotrophic pathogens are activated and regulated by JA and ethylene rather than by SA signalling pathways [68][69][70]. Wounding and subsequent treatment with jasmonates would induce the synthesis of JA and ethylene [71,72]; the involvement of the latter in reducing rots has been proved, e.g.…”

The fresh produce industry is constantly growing, due to increasing consumer demand. The shelf-life of some fruit, however, is relatively short, limited by microbial contamination or visual, textural and nutritional quality loss. Thus, techniques for reducing undesired microbial contamination, spoilage and decay, as well as maintaining product's visual, textural and nutritional quality are in high demand at all steps within the supply chain. The postharvest use of signalling molecules, i.e. jasmonates and salicylates seems to have unexplored potential. The focus of this review is on the effects of treatment with jasmonates and salicylates on the fresh produce quality, defined by decay incidence and severity, chilling injury, maintenance of texture, visual quality, taste and aroma, and nutritional content. Postharvest treatments with jasmonates and salicylates have the ability to reduce decay by increasing fruit resistance to diseases and reducing chilling injury in numerous products.These treatments also possess the ability to improve other quality characteristics, i.e. appearance, texture maintenance and nutritional content. Furthermore, they can easily be combined with other treatments, e.g. heat treatment, ultrasound treatment. A good understanding of all the benefits and limitations related to the postharvest use of jasmonates and salicylates is needed, and relevant information has been reviewed in this paper.

“…1 or 10 µmol l -1 and higher, i.e. 500 µmol l -1 concentrations [46]. In grapefruit treated with JA at 1-10 µmol l -1 and inoculated with P. digitatum decay was reduced, with no benefits of JA treatment at 0.1 and 1000 µmol l -1 , respectively [19].…”

Controle pós-colheita da antracnose do pimentão pela levedura Rhodotorula glutinis

RESUMO:Considerando as perdas causadas em pós-colheita pela antracnose no pimentão e à ineficácia das medidas de controle atualmente utilizadas, este trabalho teve por objetivo estudar a potencialidade antagônica in vitro e in vivo de quinze isolados de leveduras à Colletotrichum sp., agente causal da antracnose em pimentão. Foi calculada a porcentagem de inibição do crescimento do fungo dos tratamentos em relação à testemunha nos testes in vitro e determinado o tamanho da área lesionada em frutos através da mensuração do comprimento da lesão em dois sentidos diametricamente opostos nos testes in vivo. As leveduras que obtiveram o melhor resultado no controle da antracnose foram identificadas através de características macroscópicas, microscópicas, fisiológicas, bioquímicas e por taxonomia molecular, sendo os isolados de levedura 13E e 13A1, os que obtiveram as melhores respostas no controle do fitopatógeno tanto in vitro quanto in vivo, identificados como pertencentes à espécie Rhodotorula glutinis.

“…Exogenous application of MeJA showed no effect on spore germination or on mycelial growth of P. expansum. A combination of MeJA at 200 μM and the BCA R. glutinis significantly reduced blue mold disease incidence by 75% and lesion diameter in pears than the application of either MeJA or R. glutinis (Zhang et al, 2009). MeJA treatment significantly reduced the postharvest diseases including blue mold in peaches.…”
