储存玉米生理指标的研究

对同一区域不同储存年限玉米样品的生活力、发芽率、呼吸强度3个生理指标及脂肪酸值进行了测定,并使用SPSS统计软件对数据作了差异显著性分析、相关性分析。结果表明:储存0～3年的玉米发芽率、呼吸强度、脂肪酸值各自间都呈显著性差异,除储存2、3年玉米的生活力无显著差异外,其它储存年限的生活力间呈显著性差异。储存时间和生活力、发芽率、呼吸强度、脂肪酸值分别呈极显著相关性;发芽率分别与生活力、呼吸强度、脂肪酸值呈极显著相关性;生活力、呼吸强度、脂肪酸值两两间呈显著相关性。

Studies on the Physiological Indexes of Stored-maize

The three physiological indexes-viability, germination rate, respiratory intensity and the fatty acid value of the maize stored for different years in the same zone were measured. Data were analyzed with significant difference, correlation by SPSS. The results showed that the germination rate, respiratory intensity, fatty acid value of maize stored for 0 - 3 years has significant difference respectively, vigor of maize stored for 2 years has not significant difference with it stored for 3 years, while that stored for other times has significant difference with each other. Storing time has greatly significant correlation with viability, germination rate, respiratory intensity, fatty acid value respectively; germination rate has greatly significant correlation with viability, respiratory intensity, fatty acid value respectively, each other of the viability, respiratory intensity, and fatty acid value has significant correlation.
