Auxin also causes the plant to develop a vascular system, to form lateral roots, and to produce ethylene.
生长素还能使植物形成维管系统，形成侧根，并产生乙烯。

Auxin, for instance, stimulates the rate of cell elongation, causes shoots to grow up and roots to grow down, and inhibits the growth of lateral shoots.
例如，生长素刺激细胞延伸的速度，促使芽和根生长，而抑制侧枝的生长。

Coronatine, like auxin, can enhance the lateral root formation under whether low K or high K.
