计算机所产生的随机数是通过一串很长的序列数模拟随机数,故称为伪随机数,在实际应用这些随机数时,这些随机数一般都能具有真实随机数的所有概率性质和统计性质,因此可以产生许许多多的序列伪随机数,一个序列的第一个随机数对应一个数,这个数称为种子数(seed)。
指定一个随机种子数 Seed
种子数这是一种随机数 Seeds
平均单果种子数 average seeds per fruit

The results showed that pollen germination rate,self-breeding rate and fruit seed number of T4 were the highest with 28 ℃/18 ℃(day/night)treatment. There was no significant difference compared with the control First.
结果表明:28℃/18℃(昼/夜)处理的T4花粉发芽率、自交结实率最高,果实种子数最多,与对照First差异不显著,表明此时T4恢复部分育性;28℃/24℃和28℃/12℃处理的T4花粉发芽率、自交结实率和果实种子数与对照差异均达到极显著水平,表现为不育。

同一阶段各土层种子数差异不大。
In different stratification of same stage, the number of seeds is nearly the same.
两个居群连香树果实长度和宽度显著相关,而种子数与果实长度和宽度均不存在显著相关。
The length of fruit in two populations was markedly correlation to its breadth, and the amount of seed was not markedly correlation to its breadth or length.
在单种样方中,我们发现不同基因型间可能存在平均单粒重和种子数之间的不同结实策略的选择。
We found high number of seed output of genotype D, but its single seed weight is much lower than other genotypes.
