From the opening
A graft joins the top of one plant to the roots of another so they share water and sugars. The fruit, leaves, and flowers are grown by the top, called the scion, so the crop is the scion's variety and not the root's. The opening covers scion wood grows the fruit, cambium is what knits, and suckers are the rootstock.
The rest of the brief — the later sections and the reading notes — opens after Stripe confirms payment.
