One of the small, oval, rounded spots upon the stem or branch of a plant, from which the underlying tissues may protrude or roots may issue, either in the air, or more commonly when the stem or branch is covered with water or earth.
A pore on the surface of the stems of some plants, allowing gas exchange between the stem and the atmosphere. Lifting- The process of digging or pulling tree seedlings from the nursery seedbeds or planting beds prior to bareroot planting in the field or in a transplant bed.
A small opening (either a pore or a slit) in the bark of the tree, through which the tree "breathes" air into the cambium and other living tissues of the outer trunk. While all trees have lenticels, some are more easily observed on twigs and young branches (such as those of Black Cherry and River Birch) than others.
A lenticel is a spongy area present in the cork surfaces of the stems, roots, and other parts of vascular plants. These structures allow for the exchange of gases between the internal tissues and atmosphere to occur across the periderm, which would otherwise prevent this exchange of gases.
