Historical evidence suggests that vytynanky began to be made in Ukraine at the end of the fifteenth to early sixteenth century, but it took quite some time before they became an integral part of the decorative arts practiced at the grass roots level. During the nineteenth century decorative paper cutouts spread all across the Ukrainian countryside.
The Stairstep container was a design that trapped root tips to force branching and yet could be stacked. However, production costs made this container difficult to manufacture. One container designer tried “root suffocation pruning.” When a root grows into a reservoir of water at the bottom, it is suffocated. The death of the root tip ...

In botany, the trunk (or bole) is the stem and main wooden axis of a tree, [1] which is an important feature in tree identification, and which often differs markedly from the bottom of the trunk to the top, depending on the species. The trunk is the most important part of the tree for timber production.
Adventitious roots arise out-of-sequence from the more usual root formation of branches of a primary root, and instead originate from the stem, branches, leaves, or old woody roots. They commonly occur in monocots and pteridophytes, but also in many dicots , such as clover ( Trifolium ), ivy ( Hedera ), strawberry ( Fragaria ) and willow ( Salix ).
In botany, a root sprout or sucker is a severable plant that grows not from a seed but from the meristem of a root at the base of or a certain distance from the original tree or shrub. Root sprouts may emerge a substantial distance from the base of the originating plant, are a form of vegetative dispersal , and may form a patch that constitutes ...
The roots may grow downward from the stem or upward from typical roots. Some botanists classify them as aerating roots rather than aerial roots if they emerge from the soil. The surface of these roots is covered with porous lenticels, which lead to air-filled spongy tissue called aerenchyma.
