Abstract：The leaf areas,chlorophyll contents,soluble solid contents and lycopene contents of 17 accessions of pure diploid mini-watermelons(Citrullus lanatus)cultivars and homologous tetraploid watermelons were determined.The results showed that four major agronomic characteristics were increased along with the increase of ploidy.Among which,the leaf areas of tetraploid watermelons were increased by 22.43 %-165.80 %.The chlorophyll a+b contents in the leaf blades of majority homologous tetraploid watermelons were increased 1.57 %-17.28 %,compared with the diploid.And the soluble solid contents in the center of watermelons were increased by 1.80 %-5.69 %.The lycopene contents were increased by 8.66 %-88.41 %,showing significant or extreme significant differences to the diploid.
