rooting

The algorithm constructs matrixes by using covariation or covariation coefficient and estimates bearing and range of near-field sources by rooting method.

本方法利用协变异(或协变异系数)构造矩阵,并通过求根的方法估计近场源的方向角和距离参数。

The result showed that the successful rooting system was closely related to the concentration of macronutrient of MS medium, auxin concentration and developing state of the explant.

结果表明，培养中无机盐浓度、外源激素水平、种类以及外植体的发育状况等对试管嫩茎生根具有明显影响。
