How do cuttings grow?
In article , Peter Sutton
writes Its a huge subject, and I was really only questioning the speed at which roots form. I had always assumed that they grew at a linear rate, ie after 10 days the roots were twice as long as after 5 days. But my recent observation implies that for 10 days nothing appears to happen, then two inch roots can suddenly grow in only two or three days. I would suspect (please note I am a non-technical person!) that for the first few days the cutting can use the salts etc from the sap in the actual stem and then the cells at the base click over to root production. I thought this was what happened as sometimes you can keep a cuttings going for quite a while especially if long, however in the end the cutting never produces roots and then dies. So I assumed it was getting enough sustenance as it were, to exist for so long. Like trees and shrubs that get uprooted but flower or come into leaf before dying eventually. On the other hand this probably labels me as a right nitwit in the propagating department -- Janet Tweedy Dalmatian Telegraph http://www.lancedal.demon.co.uk |
