Galia' melons were grown under controlled conditions and pruned to bear two fruits with 19 leaves per plant. Leaves and fruits were sampled and analysed at eight different stages. Pericarp cell division ,and enlargement occurred during the first week after anthesis but only cell enlargement was responsible for fruit growth thereafter. An increase in fruit-peel surface during the first 3 days after anthesis (DM) was due mainly to epidermal cell division. During the following 11 days fruit-peel area increased due to increases in epidermal cell size. At 14 DM no further epidermal cell enlargement occurred, probably due to an increase in cuticle thickness. After this stage fruit peel surface increased due to cracks in the epidermal layer which preceded and probably initiated lenticel development. In leaves adjacent to developing fruit, a reduction in starch occurred during the last week of fruit development, coinciding with sharp increases in glucose, fructose and sucrose levels and an increase in total fruit-flesh sucrose from 50.4 9 to 111.6 9 per fruit, illustrating the importance not to harvest prematurely.'Galia' tipe spanspek is onder beheerde klimaatstoestande verbou en gesnoei sodat daar twee vrugte en 19 blare per plant ontwikkel het. Blare en vrugte is op agt verskillende stadia gemonster en ontleed. Deling en vergroting van peri karp selle het in die eerste week na antese plaasgevind maar daarna was slegs selvergroting vir vruggroei verantwoordelik, 'n Vergroting in vrugskil oppervlak gedurende die eerste 3 dae na antese was hoofsaaklik die gevolg van selc;leling. Gedurende die volgende 11 dae het die vrugskil oppervlak vergroot weens vergrotings in die epidermissef/e. Twee weke na antese het epidermisse//e nie verder vergroot nie, waars~ynlik weens 'n verdikking van die kutikula. Na hierdie stadium het vrugskil oppervlakte vergroot weens barsies in the epidermale sellaag wat lentiselontwikkeling voorafgegaan en waarskynlik ge"inisieer het. In blare naasliggend aan die ontwikkelende vrugte het 'n afname in stysel-inhoud gedurende die laaste week van vrugontwikkeling plaasgevind. Dit het saamgeval met skerp toe names in glukose, fruktose en sukrose konsentrasies in blare en 'n toename in die totale sukrose inhoud van 50.4 9 tot 111.6 9 per vrug. Dit iIIustreer waarom vrugte slef.js op die volryp stadium gepluk behoort te word. . ,
