Dear All:

I am surprised no one has mentioned, in regard to virus in Hippeastrum
and, for that matter, other plants, tissue culture. Vast numbers of
growers use this method to get rid of virus in plants. Hadeco, as an
example, use this method to clean a stock. Those of you who have visited
the labs on the farm just outside Johannesburg, will no doubt recall the
great number of plants being propagated this way. After the initial
treatment, the new plants are grown on in, more of less, sterile
conditions in a special greenhouse. Hadeco perform this work, under
contract, for many growers in Europe. To say that all stocks are
infected I feel is not only not true but unfair. Growers in the
Netherlands are very conscious of the need to sell only the best
possible stock. Cheers, John E. Bryan
