The most important observation made from our experimental data is that the meristem is a highly plastic tissue, which undergoes substantial changes in domain organization and cell behavior in response to environmental and developmental cues.

Large differences exist, for example, in the rate at which tundra plants can respond to changes in weather and climate, due to differences in allocation to stems versus leaves or to secondary chemistry versus new growth , in the ability to add new meristems , and in the constraints on the amount of growth that can be achieved by a single meristem within a single year (i.e., determinate versus indeterminate growth).
"Yes, but the key to understanding and manipulating plant form lies in unraveling the communication machinery that enables shoot apical meristem cells to continuously coordinate the processes of stem-cell proliferation and organ primordia initiation."

If the pest can find no host 'it never develops a growing shoot (apical meristem), it never becomes photosynthetic, and it dies.
Wood is a tissue which is formed under the bark of the trunk by the meristem, the cambium.
The superiority of the technique is warranted by the fact that perfectly healthy clones could be produced by the technique of meristem culture.
Apart from slight leaf mottling, these viruses appear to be symptomless, but laboratory experiments using virus-free material prepared by meristem culture suggest that growth and yield are considerably retarded by their presence-which is the general state of the crop as at present cultivated.
