Pruning could affect DNA

Endoreduplication is the process of chromosome duplication without cell division and a new study has shown that a plant's ability to do this after damage may contribute to its chances of survival. The extra DNA may speed up the rate at which proteins can be manufactured, as well as make individual cells bigger. In the study, which compared two cultivars of Arabidopsis, the one which exhibited endoreduplication was able to to this actually able to quickly regrow and increase its seed production after clipping. (source: Some plants duplicate their DNA to overcome adversity (August 2011). This may have evolved as a response to grazing pressure. If found in other plants, however, the implications for modern-day horticulture, will be obvious.

To develop and maintain a tree with a single, clean trunk, keep an eye out for basal shots and remove promptly
