Muskmelon ＂Yu mei ren＂ was taken as the experimental material and the mixture of calcium nitrate （0.5%） and IAA （20×10. ） was sprayed to melon plants in order to study the effect of calcium nitrate ＋ IAA treatment on the maturation of muskmelon fruit under low temperature stress at night. The results showed that calcium nitrate ＋ IAA treatment increased significantly soluble solids, vitamin C, fructose, glucose, sucrose and total sugar content in muskmelon fruit at the night temperatures of 12 ℃ and 9 ℃. Total sugar contents increased 12.63 mg・g. and 9.877mg・g. at the 9 ℃and 12 ℃, and the sucrose also raised 7.403 mg・g. and 5.768 mg・g. . The malic acid and tartaric acid contents reduced 16.7% at 12℃ and 18.4% at 9℃. So calcium nitrate ＋ IAA could reduce content of organic acid in muskmelon fruit and improve its nutritional quality.
