Elongationgrowth and basal growth are decreased gradually, and first elongationgrowth is restrained under drought stress in laboratory.
室内干旱胁迫条件下，臭柏的伸长生长和地径生长逐渐减少，而且伸长生长优先受到抑制。

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。

Certain concentration of sucrose solution is helpful to growth of pollen tube; both 10% and 20% sucrose solutions can significantly increase elongation velocity of pollen tube.
