Re: seeds aren't germinating. HELP !
I have just found this online.
The reason why bananas cannot be grafted, as suggested by Anthony Whyte (15 February, p 24), can be found in the Royal Horticultural Society’s new book, Science in the Garden: the scientific basis of horticultural practice (Blackwell Publishing, £19.99).
For a graft to unite, the root stock and the piece of shoot to be attached to it must both possess cambial tissue, a thin layer of cells inside the vascular bundles that divide to create a successful union. Monocotyledonous plants (bananas, palm trees, lilies, grasses and so on) do not possess a cambium, however, and grafts are therefore very difficult to achieve.
If successful, the two cut surfaces must be held permanently together by tying or taping, which in all likelihood would further increase the chance of disease.
