Two high-performance liquid chromatography (HPLC) methods for ascorbic acid (AA) quantification were compared in three cultivars of melon (Cucumis melo L.) fruits. Both procedures were analogous except for the extraction medium used: 6 % meta-phosphoric acid and 3 % citric acid. The general conclusion is that 3 % citric acid is a better extraction medium compared to 6 % meta-phosphoric acid and...

fusarium wilt of melon is a destructive fungal disease throughout the world. in this study, the evolutionary relationships among isolates of different formae speciales of fusarium oxysporum was examined, with a special emphasis on the forma specialis melonis. bootstrapped maximum likelihood analysis of the elongation factor-1α (ef-1α) sequence was conducted on 16 iranian and 11 foreign isolates...

In August 1946, marked viruslike symptoms were observed on watermelon {Citrullus vulgaris Schrad.) and muskmelon (Cucumis melo L.) plants in a field at Merrimac, Wis. Inoculations from infected plants to tobacco (Nicotiana tabacum L.), cucumber (Cucumis sativus i.)> ö.nd watermelon demonstrated that the disease was of virus origin. Isolates from watermelon and muskmelon were identical, and one ...

Triton X-100 solubilized chloroplast DNA but not nuclear DNA from a mixture of chloroplasts and nuclei. The buoyant density of chloroplast DNA was different from that of the satellite DNA in all of the species examined (Phaseolus coccineus, Cucumis sativus, Cucumis melo, Antirrhinum majus, Vicia faba, Oenothera fruiticosa youngii). Chloroplast DNA constituted between 4.3% and 0.25% of the total...
