Hajtáscsúcsról

Hajtáscsúcsról is a Hungarian term that translates to "shoot tip" or "apical bud" in English. It refers to the actively growing point at the very end of a plant's stem or branch. This region is characterized by a high concentration of meristematic cells, which are undifferentiated cells capable of rapid division and growth.

The hajtáscsúcsról is crucial for plant development. It is responsible for primary growth, meaning the elongation of stems and roots. Within the shoot apical meristem, new leaves, flowers, and stem tissues are produced. Hormones, particularly auxins, play a significant role in regulating the growth and development originating from the hajtáscsúcsról. The presence of an intact hajtáscsúcsról also typically exerts apical dominance, a phenomenon where the main stem grows more vigorously than lateral branches. Removing the hajtáscsúcsról can often stimulate the outgrowth of lateral buds, leading to a bushier plant structure. This principle is utilized in horticultural practices like pruning and pinching to manage plant shape and encourage flowering or fruiting. Understanding the function of the hajtáscsúcsról is fundamental to plant biology and agriculture.
