从主枝或副主枝上生长出的小枝。又叫单位枝。由植物的芽原基发育而来。
n. offshoot
misc. lateral branch ; side shoot
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。
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.
秋天里修剪以控制树形；将侧枝剪去三分之二以保持生长旺盛。
Prune in the autumn to keep the plant under control; reduce side shoots by two-thirds to keep the growth strong.
我们的工作就是修剪这些树的侧枝。
