Micrographs from immature fruit showed incompletely formed chromoplasts. A combination of distinct pigment-bearing chromoplasts and incompletely formed chromoplasts was observed in mature watermelon micrographs. Electron micrographs showed chromoplasts changing from a less organized globular form in immature to a symmetrical form in mature to an asymmetrical form in overmature watermelons. This study furthers our understanding of watermelon physiology and the effect of maturity on compartmentalization of lycopene. MS 20070962 Submitted 12/21/2007, Accepted 3/18/2008 |
