Navel oranges are reportedly susceptible to postharvest peel disorders, including chilling injury and aging/stem end rind breakdown. These and other physiological disorders are sometimes given the common term “navel rind breakdown.” California citrus industry reports on recent incidences of navel rind breakdown suggested that some instances of this disorder were similar to “postharvest pitting,” a disorder that we have observed in a number of Florida citrus varieties. Thus, we decided to define the morphology and etiology of pitting of `Washington' navel orange (Citrus sinensis L.) peel. The disorder was characterized by the collapse of clusters of oil glands and was stimulated by wax application and high temperature (≥13 °C) storage. Internal ethanol levels of waxed fruit stored at high temperature (13 or 21 °C) were significantly higher among fruit that developed pitting than those that did not. The pitting observed in these studies is comparable to previously observed navel orange disorders that have occurred without known cause. Navel orange pitting is morphologically and etiologically distinct from chilling injury and aging/stem end rind breakdown, but is similar to postharvest pitting of Florida citrus fruit.

Water Uses

The water problems in Marina Baja district, located in the north of Alicante Province, southeast Spain, gives rise to very interesting practices in the management of this scarce resource. The key issue in water use both in the Júcar Catchment and in Marina Baja district is the growing demand for water in inland areas for intensive crop irrigation (principally fruit, medlars and citrus fruit) and the growth in demand for water for urban use, as well as for use in the tourist industry and its related services mainly in the towns in the coastal areas, due to strong growth in tourism. This trend of increasing demand has created a tense situation as well as conflict between existing water uses and the need for integrated water management in the area. This step implies that procedures for water exchange contracts have to be developed, that are significantly different from emerging water markets.

Citrus Reticulata Blanco

Considering the huge economic loss caused by postharvest diseases, the identification and prevention of citrus postharvest diseases is vital to the citrus industry. In 2018, 16 decayed citrus fruit from four citrus varieties—Satsuma mandarin (Citrus unshiu), Ponkan (Citrus reticulata Blanco cv. Ponkan), Nanfeng mandarin (Citrus reticulata cv. nanfengmiju), and Sugar orange (Citrus reticulata Blanco)—showing soft rot and sogginess on their surfaces and covered with white mycelia were collected from storage rooms in seven provinces. The pathogens were isolated and the pathogenicity of the isolates was tested. The fungal strains were identified as Lasiodiplodia pseudotheobromae based on their morphological characteristics and phylogenetic analyses using the internal transcribed spacer regions (ITS), translation elongation factor 1-α gene (TEF), and beta-tubulin (TUB) gene sequences. The strains could infect wounded citrus fruit and cause decay within two days post inoculation, but could not infect unwounded fruit. To our knowledge, this is the first report of citrus fruit decay caused by L. pseudotheobromae in China.

AbstractEfficient methods to achieve the safe decontamination of agricultural products are needed. Here, we investigated the decontamination of citrus fruits to test the antifungal potential of a novel non-thermal gas plasma apparatus, termed a roller conveyer plasma instrument. This instrument generates an atmospheric pressure dielectric barrier discharge (APDBP) plasma on a set of rollers. Penicillium venetum was spotted onto the surface of the fruit or pericarps, as well as an aluminium plate to act as a control, before performing the plasma treatment. The results showed that viable cell number of P. venetum decreased with a decimal reduction time (D value or estimated treatment time required to reduce viable cell number by 90%) of 0.967 min on the aluminium plate, 2.90 min and 1.88 min on the pericarps of ‘Kiyomi’ (Citrus unshiu × C. sinensis) and ‘Kawano-natsudaidai’ (C. natsudaidai) respectively, and 2.42 min on the surface of ‘Unshu-mikan’ (C. unshiu). These findings confirmed a fungicidal effect of the plasma not only on an abiotic surface (aluminium plate) but also on a biotic surface (citrus fruit). Further development of the instrument by combining sorting systems with the plasma device promises an efficient means of disinfecting citrus fruits during food processing.

Morphology Characterization

The Nanfengmiju (Citrus reticulata cv. Nanfengmiju), a high-quality local variety of mandarin, is one of the major fruit crops in Jiangxi Province, China. Citrus melanose and stem-end rot, two common fungal diseases of Nanfengmiju, are both caused by Diaporthe spp. (syn. Phomopsis spp.). Identification of the Diaporthe species is essential for epidemiological studies, quarantine measures, and management of diseases caused by these fungi. Melanose disease was observed on Nanfengmiju fruit in Jiangxi Province of China in 2016. Based on morphological characterization and multi-locus phylogenetic analyses, three out of 39 isolates from diseased samples were identified as D. passifloricola. Since these three isolates did not cause melanose on citrus fruit in the pathogenicity tests, they were presumed to be endophytic fungi present in the diseased tissues. However, our results indicate that D. passifloricola may persist as a symptom-less endophyte in the peel of citrus fruit, yet it may cause stem-end if it invades the stem end during fruit storage. To the best of our knowledge, this is the first report of D. passifloricola as the causal agent of the stem-end rot disease in Citrusreticulata cv. Nanfengmiju.
