ABSTRACT

The aim of this work was to study the effect of postharvest light treatment as a potential degreening method on ‘Okitsu’ Satsuma mandarin (Citrus reticulata Blanco). Furthermore, a possible synergistic effect of light and ethephon treatment was also evaluated. For this, mature green fruit were harvested and treated. The treatments were: 1) exposing the fruit to increasing periods of time of photosynthetically active radiation (PAR); 2) the combination of a traditional ethephon degreening method with the most effective PAR treatment. The results show that 12 h and 24 h of PAR treatments were the most favourable to obtain the better effects of degreening, not affecting the rest of quality parameters. The combination of the 24 h of PAR and ethephon treatments was not effective to degreen the fruit. The present work is the first step in the approach to the study of PAR treatment as a degreening method on citrus and, according to the results, we consider it could be a promising degreening treatment on ‘Okitsu’ mandarin.

摘要

这项工作的目的是研究采后光处理作为潜在的降级方法对'Otsutsu'萨摩柑（Citrus reticulata）的影响。布兰科）。此外，还评估了光和乙烯利处理的可能的协同作用。为此，收获并处理了成熟的绿色水果。处理方法是：1）将果实暴露于光合作用活性辐射（PAR）延长的时间段；2）传统的乙烯利降级方法与最有效的PAR治疗相结合。结果表明，PAR处理12 h和24 h最有利于获得更好的定级效果，而不影响其余质量参数。PAR和乙烯利处理24小时的组合对水果结实效果不佳。目前的工作是研究PAR治疗柑橘的分级方法的第一步，根据研究结果，
