【摘要】 数据分析结果表明,紫花苜蓿(Baralfa32IQ)植株群体每花序的花朵数及其频数,荚内种子数及其频数分别构成数字连续的近似正态分布的图形。每花序的花朵平均数为18.5,均数标准误约为6.5,最小数是2,最大数是61,众数是17,中位数约为17.9,拟合的正态分布曲线函数为y=16.5)2。荚内种子平均数为7.3,均2(x-18.56.52πe-1数标准误约为3.3,最小数是1,最大数是19,众数是7,中位数约为7.2,拟合的正态分布曲线函数为y=13.3)2。2(x-7.33.32πe-1更多还原

【Abstract】 The quantity characteristics of the inflorescence flowers and pod seeds of Medicago sativa (Baralfa 32 IQ) were studied. The inflorescence flower numbers showed a formal distribution pattern which can be represented by the following model:y=16.52πe-12(x-18.56.5)2. The mean number of flowers per inflorescence was 18.5, std. error of mean 6.5, minimum 2, maximum 61, mode 17, and the median was 17.9. The seed numbers per pod also showed a formal distribution pattern which can be represented by the following model:y=13.32πe-12(x-7.33.3)2. The mean number of seeds per pod was 7.3,std. error of mean 3.3,minimum 1,maximum 19,mode 7, and the median was 7.2.更多还原
