Final answer:
In grafting and budding, the term for when the bark peels easily is 'slipping'. It refers to the optimal condition of the bark for these techniques, indicating active growth of the phloem and cambium layers, which is essential for the success of the grafting process.
Step-by-step explanation:
When some grafting and budding techniques require peeling the bark, this process is referred to as the bark slipping. The bark includes the phloem, the cork cambium, and the products of the activity of one-to-many cork cambia, along with small portions of the primary phloem, cortex, and epidermis. The appearance and texture of the bark can vary widely, which influences how the cork cambium behaves and how easily the bark may slip during the grafting or budding process. The correct answer is b) slipping. This term refers to when the bark easily peels away from the wood, facilitating grafting and budding techniques.
Grafting and budding are horticultural techniques that join parts of plants so they grow as one. In some cases, the bark needs to peel back, or slip, from the woody layers beneath. This slipping is often an indication that the bark is in the right condition for successful grafting, as it means the phloem is active and growing, which is essential for the new graft to establish and thrive. In horticultural practices such as grafting and budding, the condition of the bark is critical.
