【摘要】 通过测杂交柚、沙田柚的真叶、翼叶之长、宽及其叶面积, 然后建立回归方程, 再进行测算检验, 结果表明长、宽叶面积公式不如长×宽叶面积公式精确。并得出柚真叶面积的测算公式为y= 0-5326 + 0-7289x ( 式中y 指叶面积, x 指叶长×宽,r= 0-9924 , n = 184) , 翼叶面积公式为y = 0-0495 + 0-7031x ( 式中y 、x 的含义同真叶, r= 0-9912 , n = 184) 。更多还原

【Abstract】 According to the study of teak leaf area reyression equation and test, it shows that length×width leaf area formula is accurater than length, width Leaf area formula. The formula for measuring and calculating area of teak true leaf is y=0 5326+0 7289x (y is area and x is leng×width of leaf, r=0 9924, n=184), and that of flank leaf is y=0 0495+0 7031x (y and x same true leaf area formula, r=0 9912, n=184).更多还原
