The fruit flesh of wild watermelons is watery, but typically hard-textured, pale-coloured and bland or bitter. The familiar sweet dessert watermelons, C. lanatus, featuring non-bitter, tender, well-coloured flesh, have a narrow genetic base, suggesting that they...
متن کاملFirst report on laxative activity of Citrullus lanatus

Rats were divided in 5 groups of 6 animals each, first group as control, second group served as standard (sodium picosulfate) while group 3, 4 and 5 were treated with fruit pulp aqueous fruit pulp extract of Citrullus lanatus at doses of 250, 500 and 1000 mg/kg...
متن کاملInheritance of Resistance to Powdery Mildew Race 2 in Citrullus lanatus var. lanatus
Information on the mode of inheritance of powdery mildew resistance in watermelon is important for designing a breeding strategy for the development of new cultivars. Resistance in the watermelon accession PI 270545 was investigated by generation means analysis by crossing it with susceptible PI 267677. The analyses showed involvement of two genes, a recessive resistance gene, pmr-1, and a domi...
متن کاملPhysico-chemical compositions of the red seedless watermelons (Citrullus Lanatus)
Changes of physico-chemical properties such as size, weight, moisture content, total soluble solid (TSS), colour, pH, total acidity and sugar content of red seedless watermelon during storage at room temperature (± 28oC; 70-80% RH) were investigated. The average weight, diameter and length of red seedless watermelon were 5.94 kg, 22.0 cm and 21.8 cm respectively. The length to diameter ratio wa...
متن کاملLycopene and Citrulline Contents in Watermelon (Citrullus lanatus)
Lycopene and citrulline contents of 9 diploids (2X) and their artificially induced autotetraploids (4X) and autotriploids (3X) were determined in mature fruit. Changes in lycopene and citrulline during fruit development was studied using fruit of variety XYXA with three different ploidy levels from 15 to 40 days after pollination (DAP). Polyploids, especially triploids, had higher levels of lyc...
