macroelement

In grain, the content of macroelement and microelement can be controlled by different genetic mode. The content of macroelement in grain can be controlled more by genetic effect. The content of microelement in grain can be controlled less by genetic effect.

大量元素和微量元素在种子中含量的遗传变异受控制的方式是不相同的，大量元素含量的变异受到较多遗传效应的控制，而控制微量元素含量变异的遗传效应相对较少。
