摘　　要：为了探索非离体、便捷、准确的芒果果实体积测定方法,笔者通过测定台农一号芒果果实实际体积(V实际)、纵径(a)和相互垂直方向上的最大横径(b,c),经过矫正法和线性回归法推导出果实体积(V)估算公式,并利用公式分析台农一号芒果果实体积与其主要营养、风味品质等指标间的线性回归关系。结果表明,矫正法和线性回归法推导的体积公式分别为:V=0.51 abc和V=0.494 5 abc+2.506(r2=0.989 8),都能够较准确地估算台农一号芒果果实体积。通过线性回归分析可知,果实体积与可食率和糖酸比呈线性正相关回归关系,其回归方程分别为:V=0.619 1+0.000 559 abc(r^2=0.2056)和y=13.328 1+0.034 7x(r2=0.179 5),与可溶性糖和总酸含量的线性回归关系都不显著。由此可见,台农一号芒果果实体积越大,则其可食率和糖酸比越高,风味品质越佳。Mango Tainong 1（ Mangifera indica Linn.） were measured in terms of actual volume（ Vactual）,longitudinal diameter（ a） and mutually orthogonal maximum transverse diameters（ b,c） to estimate the actual mango volume by using both the correction method and the linear regression method,and the edible percentage of the fruit and the ratio of sugar to acid in the flesh were also determined to correlate the fruit volume with the flavor quality of the fruit. The actual mango volume was estimated by using the formula V = 0. 51 abc and V = 0. 494 5 abc ＋ 2. 506（ r^2= 0. 989 8） derived from both the correction method and the linear regression method. The fruit volume was found significantly correlated with the edible percentage of the fruit and the ratio of sugar to acid in the fruit flesh,and its formula were V = 0. 619 1 ＋ 0. 000 559abc（ r^2= 0. 205 6） and y = 13. 328 1 ＋ 0. 034 7x（ r^2= 0. 179 5,but the fruit volume was not significantly correlated to the soluble sugar or the total acid content in the fruit flesh. This indicates that the mango fruit with larger volume had higher edible percentage and higher acid-sugar ratio and hence much better flavor quality.
