'Grafting can be used to transmit plant pathogens which are difficult to spread in other ways'

摘要

enough of the vascular system remained functioning for the natural supply of water to the top to continue. The process depends on the fact that, generally, mature plant cells in vegetative tissue have a much wider ability to grow and differentiate than do animal cells. So once the grafter has put the two halves in place, new tissues form that bind the parts together.
