“…Significant differences in lesion size were found among the inserted fungal isolates, but not between the two apple cultivars. Mycelial plugs have also been used for inoculation with Botrytis cinerea [ 26 ]. These methods are, however, considerably more time-demanding than the spore-based methods, and have not yet been used for screening large sets of cultivars/genotypes.…”

“…Both of these genes are associated with inter-cultivar variation in fruit firmness at harvest and after storage [ 77 , 78 ], which appears to be an important component in the resistance against storage rots. Application of n-propyl dihydrojasmonate similarly induced ethylene production and an increased activity of several ethylene-related genes, and also resulted in smaller lesions on apples inoculated with B. cinerea [ 26 ].…”

Fungal storage rots like blue mould, grey mould, bull’s eye rot, bitter rot and brown rot destroy large amounts of the harvested apple crop around the world. Application of fungicides is nowadays severely restricted in many countries and production systems, and these problems are therefore likely to increase. Considerable variation among apple cultivars in resistance/susceptibility has been reported, suggesting that efficient defence mechanisms can be selected for and used in plant breeding. These are, however, likely to vary between pathogens, since some fungi are mainly wound-mediated while others attack through lenticels or by infecting blossoms. Since mature fruits are considerably more susceptible than immature fruits, mechanisms involving fruit-ripening processes are likely to play an important role. Significant associations have been detected between the susceptibility to rots in harvested fruit and various fruit maturation-related traits like ripening time, fruit firmness at harvest and rate of fruit softening during storage, as well as fruit biochemical contents like acidity, sugars and polyphenols. Some sources of resistance to blue mould have been described, but more research is needed on the development of spore inoculation methods that produce reproducible data and can be used for large screenings, especially for lenticel-infecting fungi.

“…For inoculation, a wound of 5-mm diameter and 3-mm depth was made between the vertical and horizontal parts at the equator of the fruit using a sterilized scalpel (Suktawee et al, 2019). The 20 ml of spore suspension was inoculated into the center of the wound of each fruit using a micropipette and allowed to airdrain for pathogen settlement.…”

Green mold caused by Penicillium digitatum is an important factor limiting the shelf life of mandarin fruit. In this study, the effect of ultraviolet-C (UV-C) irradiation on cellular structure, endogenous jasmonic acid (JA), and development of P. digitatum in satsuma mandarin fruit was investigated. UV-C treatments included 0 (untreated control), 3, and 10 kJ m−2 or the exposure time of 0, 1.18, and 4.52 min, respectively. The UV-C dose of 10 kJ m−2 significantly reduced the development of P. digitatum both in vitro and in vivo, resulting in the maintenance of the cellular structure of the albedo tissue. The production of malondialdehyde (MDA) was decreased upon UV-C treatment of 10 kJ m−2. The concentration of JA increased in the treatment of 10 kJ m−2 compared to the treatment of 3 kJ m−2 and the control. UV-C irradiation increased total phenolic and total flavonoid concentrations and DPPH radical scavenging capacity. These results suggest that UV-C at 10 kJ m−2 has a potential to control green mold caused by P. digitatum, maintain cellular structure, stimulate the accumulation of JA, and induce biochemical compounds in satsuma mandarin.
