通过对2个普甜玉米、2个加强甜玉米、2个糯玉米灌浆期子粒含水率、含糖量、呼吸强度、风味食味的测定,探讨鲜食甜、糯玉米的适采期和采后保鲜技术。结果表明：普甜、加强甜玉米适采期为授粉后24～27天，糯玉米为授粉后23～25天。收获后贮存期间甜玉米可溶性糖含量与贮存温度极显著相关，相关系数r=0．9804**；与呼吸强度显著相关，相关系数r=0．942*。贮存温度与呼吸强度极显著相关，相关系数r=0．9963**。常温下呼吸强度最大，达到76.7CO2mg／kg（鲜重）·h，是-30℃冷冻贮存的12倍。生产上可以通过控制贮存温度和时间，达到降低呼吸强度和糖分分解速率，保证鲜玉米品质的目的。
Through the determination of grain water content, sugar content, respiration intensity and flavor and taste of two sweet corn, two sweet corn and two waxy corn at grain filling stage, the suitable harvest period and postharvest Preservation technology. The results showed that: sweet, sweet corn to strengthen the harvest period of 24 to 27 days after pollination, waxy corn 23 to 25 days after pollination. The soluble sugar content of sweet corn during storage was significantly correlated with storage temperature after harvest, the correlation coefficient r = 0.9804 **, and the respiratory intensity was significantly correlated with the correlation coefficient r = 0.942 *. Storage temperature and respiratory intensity were significantly correlated, the correlation coefficient r = 0.9963 **. Respiration at room temperature, the largest, reaching 76.7CO2mg / kg (fresh weight) · h, is frozen at -30 ℃ 12 times. Production can be controlled by the storage temperature and time to achieve lower respiratory intensity and sugar decomposition rate, to ensure the quality of fresh corn purposes.
