“…As surface waxes regulate water loss and act as the first barrier to pathogen attack, we investigated whether ethylene is able to induce epicuticular wax changes in 'Navelate' oranges. We showed that ethylene increases surface wax when applied for prolonged periods, which is in agreement with previous findings in apple fruit (Ju and Bramlage, 2001) and with the fact that gibberellic acid delaying peel senescence and wax accumulation in oranges (El-Otmani and Coggins, 1985a). The effect of ethylene on wax ultrastructure of citrus fruit has not been investigated to date.…”

“…In these reports, it was also suggested that new wax may push the initial wax away, especially the most aged or prone to crack. Interestingly, new waxes in citrus fruit are richer in fatty acids (Freeman et al, 1979), while ethylene has an important impact increasing fatty acids in apples (Ju and Bramlage, 2001). …”

“…The effect of ethylene on the epicuticular wax of horticultural crops has been little studied (Ju and Bramlage, 2001). To our knowledge, there has been no report on its effect on natural production of wax or its structure in citrus fruit in spite of its effect in reducing peel damage caused by abiotic (Lafuente et al, 2001;Lafuente and Sala, 2002) and biotic (Marcos et al, 2005) stresses in this crop.…”

Elsevier Cajuste, JF.; Gonzalez-Candelas, L.; Veyrat, A.; García-Breijo, F.; Reig Armiñana, J.; Lafuente, MT. (2010) The effect of ethylene (2 L L −1 ) on total and soft epicuticular wax content and wax morphology has been investigated in mature 'Navelate' (Citrus sinensis, L. Osbeck) oranges held under non-stressful environmental conditions (22• C and constant high relative humidity (90-95% RH)). In addition, the objective of the study was to understand whether the ethylene-induced changes in epicuticular wax might participate in the beneficial effect of ethylene reducing non-chilling peel pitting, by modifying peel water, osmotic or turgor potential, or disease incidence caused by Penicillium digitatum (Pers.:Fr.) Sacc. Ethylene increased total and soft epicuticular wax content in 'Navelate' fruit and induced structural changes in surface wax that might be related to the formation of new waxes. Changes in epicuticular wax morphology, but not in its content, might be involved in the protective role of ethylene reducing non-chilling peel pitting, although the beneficial effect of the hormone is not related to water stress. Cell water and turgor potentials in freshly harvested fruit and fruit stored in air under non-stressful conditions suggest that water stress is not a limiting factor leading to the development of this physiological disorder. In addition, the results indicated that formation of new waxes in fruit treated with ethylene may partially cover stomata, cracks or areas lacking wax occurring in stored fruit and is likely to improve physical barriers to P. digitatum penetration.

“…Todavia, a causa provável do distúrbio é a biossíntese de -farneseno no tecido da casca, e sua subsequente oxidação a trienos conjugados, ocasionando a degradação de células e o escurecimento do tecido (Emongor et al, 1994;Ju & Curry, 2000). O etileno promove a biossíntese de -farneseno e, portanto, aumenta a incidência de escaldadura (Emongor et al, 1994;Ju & Bramlage, 2001). Portanto, a inibição da produção de etileno pela aplicação pré-colheita de AVG reduz a ocorrência de escaldadura em maçãs (Ju & Curry, 2000;Ju & Bramlage, 2001), conforme observado no presente trabalho.…”

O objetivo deste trabalho foi avaliar os efeitos da pulverização pré-colheita de macieiras 'Gala' e 'Fuji' com aminoetoxivinilglicina (AVG) sobre a qualidade dos frutos e a ocorrência de distúrbios fisiológicos e doenças. O experimento foi conduzido nos anos de 2005 e 2006, com pulverização de AVG (30 dias antes do início da colheita comercial dos frutos) nas doses de 0; 125 e 250 mg L-1, sendo que, na segunda safra, também foi utilizada a dose de 62,5 mg L-1. Em maçãs 'Gala', o aumento na dose de AVG reduziu o desenvolvimento de coloração vermelha e a permeância à perda de água na casca. Nesta mesma cultivar, em frutos avaliados após armazenamento refrigerado (três meses a 0±0,5ºC/90-95% UR), seguido de uma semana de vida de prateleira (20±4ºC/60-70% UR), o tratamento pré-colheita com AVG aumentou a incidência de "bitter pit", porém reduziu a incidência de escaldadura, rachadura peduncular e podridões. Em maçãs 'Fuji', o aumento na dose de AVG reduziu a incidência e a severidade de pingo-de-mel em frutos colhidos tardiamente. A pulverização com AVG aumentou a severidade de mancha foliar de 'Gala' (Glomerella cingulata).

In this study, two ursane‐type triterpenes, i. e., ursolic acid (UA) and 3‐O‐β‐acetoxyursolic acid (AUA), were isolated and quantified in Sorbus intermedia (EHRH.) PERS. fruits. UA and AUA levels differed slightly throughout fruit maturation, and both triterpenes showed similar dynamics of accumulation with the highest levels found in ripe fruits (up to 6.33±0.56 and 1.17±0.18 mg/g dw. of UA and AUA, respectively). The extracts derived from unripe fruits displayed significant cytotoxic effects against WM793, DU‐145, PC3, 8505C, Caco2 and A549 cells, but no correlation between UA and AUA levels and cytotoxicity was found. On the other hand, extracts from mature fruits were not active towards almost all of the tested cell lines. The chemometric approach showed that the extracts derived from fruits harvested earlier clustered to form a clearly distanced group from extracts prepared from more‐mature fruits. The extracts at higher concentrations formed separate groups, which indicated the concentration‐dependent effect of these extracts on the cells.
