[Method] The optimal harvest periods of the two cucumber culti- vars, Zhongnong No.19 and Zhongnong No.29, were investigated through analyzing the changes of fruit appearance （vertical diameter, transverse diameter） and quality （contents of soluble protein, soluble saccharide, and vitamin C） in the entire course of fruit growth. [Result] Zhongnong No.19 and Zhongnong No.29 grew at the fastest rate during the 5-10 d of life. The longitudinal and transverse diameter increased with time. The protein and vitamin C content of cucumber was： Zhongnong No.19 reached the highest in 8d, then decreased and became stable, while Zhongnong No.29 reached the highest in 8d, then decreased and increased again. Soluble sac- charide content of Zhongnong No.19 first rose then fell and rose again; Zhongnong No.29 had two peaks. [Conclusion] Based on the physiological and morphological index, the eighth day after blooming was the optimal harvest day for Zhongnong No.19 and Zhongnong No.29 fresh fruits.展开更多
