Although intact fruits of unripe cantaloupe (Cucumis melo L.) produce very little ethylene, a massive increase in ethylene production occurred in response to excision. The evidence indicates that this wound ethylene is produced from methionine via 1-aminocyclopropanecarboxylic acid (ACC) as in ripening fruits. Excision induced an increase in both ACC synthase and the enzyme converting ACC to et...

Genetic assessment was carried out on three Italian melon accessions by sequence and structural analysis of the internal transcribed spacer 1 (ITS1) from three populations belonging to two Cucumis melo L. varieties (madras and tendral). Alignment of the 18S-5.8S-26S sequences from three melon accessions showed that there were three single-nucleotide polymorphisms (SNPs) and one short insertion-...

Surveys of yellowing viruses in plastic tunnels and in open field crops of melon (Cucumis melo cultivar catalupo), oriental melon (C. melo cultivar oriental melon), and cucumber (C. sativus) were carried out in two melon-growing areas in 2014, Korea. Severe yellowing symptoms on older leaves of melon and chlorotic spots on younger leaves of melon were observed in the plastic tunnels. The sympto...

Tendral type cultivar melons (Cucumis melo L., inodorus group, Winter melon variety) were stored for a 75-d postharvest period in a ventilated chamber at 10 oC ± 1 oC and 75% ± 5 % RH. Qualitative degradation of the fruit was observed mainly involving proteins and ascorbic acid. It was also found that the sugar/acid ratio increased while the glucose/fructose ratio decreased, thus making the fru...

Cucumis melo L. (C. melo) is a fruit with many medicinal properties and consumed in various countries. It utilised for chronic eczema to treat minor burns scrapes. The present study was conducted evaluate the antioxidant activity of methanolic extract Linn (MECM). A coarse powder prepared from seeds extracted methanol (absolute) by hot continuous percolation process accordance standard protocol...

Ripening-associated pectin disassembly in melon is characterized by a decrease in molecular mass and an increase in the solubilization of polyuronide, modifications that in other fruit have been attributed to the activity of polygalacturonase (PG). Although it has been reported that PG activity is absent during melon fruit ripening, a mechanism for PG-independent pectin disassembly has not been...
