周皮

The periderm replaces the outer layers of the stem as it grows, serving as a protective barrier.
随着植物茎部的生长，周皮取代其外层，作为保护屏障。
In response to injury, trees form a new layer of periderm to seal off the damaged area.
在受伤的反应中，树木会形成新的周皮层来封闭受损区域。
The periderm consists of cork cambium, cork, and phelloderm, collectively functioning in plant protection.
周皮由木栓形成层、木栓和栓内层组成，共同作用于植物的保护。
During secondary growth, the periderm is responsible for the production of bark.
在次生生长过程中，周皮负责生产树皮。
The periderm is a protective structure that develops in place of the epidermis in mature stems and roots.
周皮是一种保护结构，它在成熟茎和根中替代了表皮的位置。
Without a functional periderm, a plant would be vulnerable to desiccation and pathogen attack.
如果没有功能性的周皮，植物就会容易受到脱水和病原体攻击。
The formation of periderm helps to maintain the structural integrity of the plant as it grows larger.
周皮的形成有助于植物在生长变大时保持其结构完整性。
In deciduous trees, the periderm assists in the shedding of leaves by forming abscission layers.
在落叶树中，周皮通过形成离层帮助叶子脱落。
The cork cambium, a part of the periderm, generates the waterproof outer layer that protects against water loss.
木栓形成层，作为周皮的一部分，产生防水的外层以防止水分流失。
Periderm development is an essential process in the maturation of woody plants, contributing to their longevity.
周皮的发育是木本植物成熟过程中的重要步骤，对它们的长寿有所贡献。
