0 a stem to which part of another plant is joined so that both parts can grow together and get an advantage from a good feature of the stem --
The next section describes propagation and rootstock development, and the plant material used in extensively well-documented worldwide breeding programmes and their goals and successes.
Photosynthesis and stomatal conductances were affected by drought but in very different ways in each rootstock.
Resistant rootstocks are used to control grape phylloxera damage, but the phylloxera/grape interaction is poorly understood.
High-yielding genotypes are usually salt-sensitive, so grafting them onto resistant rootstocks can be a feasible strategy to improve salt tolerance.
The most vigorous rootstock had a trunk circumference 14 % greater than the weakest.
Seeds for rootstocks were produced by manual pollination with flower buds capped before anthesis and after manual pollination to prevent accidental cross-pollination.
Mn levels were satisfactory on all rootstocks except for the low levels on the two citranges.
The yields showed no evidence of a major effect of rootstock or interaction with scion in this trial.
