Abstract In order to study the dynamic change of nutrient contents in the development of chieh-qua
（Benincasa hispida Cogn．var．chieh-qua How.）fruit，the contents of VC，organic acid，soluble sugar and soluble protein were analyzed taking 5 chieh-qua cultivars‘Nanningmaojiegua’，‘Meihua No.5’，‘ 7-2-1-4-2-1-2-2’，‘GF-7-1-1’ and‘ CK-3-4-3-2-1-3’ as experimental material during 10，20，30，40 days after pollination．The results showed that the changes in nutrient components of VC，organic acid，soluble sugar and soluble protein were basically similar during the fruit development of these 5 chieh-qua cultivars． Among them the VC contents reached the highest level in the early stage，then decreased rapidly，and tended to be stable at the mutured stage．While the organic acid contents showed a trend of decreasing first，then increasing． The soluble sugar content showed a gradually increasing trend．The soluble protein content showed a trend of decreasing first，then increasing slightly．However，there were differences between different cultivars．
