Abstract
Method for inhibiting vitrification of plants of the Pinus species and Eucalyptus species. In the method, anti-vitrification agents containing one or more sulfated polysaccharides are used. The sulfated polysaccharides are preferably free of toxic components. Tissue culture media is also disclosed.
Claims24
A method for inhibiting vitrification comprising growing a species of Pinus or a species of Eucalyptus using a tissue culture media to which an anti-vitrification agent has been added, said anti-vitrification agent comprising a purified sulfated polysaccharide, substantially free of toxic components, or a mixture of purified sulfated polysaccharides substantially free of toxic components.
A tissue culture medium comprising growth medium for a species of Pinus and a purified sulfated polysaccharide or a mixture of purified sulfated polysaccharides, wherein the sulfated polysaccharide or mixtures thereof are substantially free of toxic components and wherein the sulfated polysaccharide has a degree of sulfation greater than 10%.
A tissue culture medium comprising growth medium for a species of Eucalyptus and a purified sulfated polysaccharide or a mixture of purified sulfated polysaccharides, wherein the sulfated polysaccharide or mixtures thereof are substantially free of toxic components and wherein the sulfated polysaccharide has a degree of sulfation greater than 10%.
In the propagation of trees of the Pinus species or Eucalyptus species by tissue culture methods, the improvement comprising adding a purified sulfated polysaccharide or a mixture of purified sulfated polysaccharides to a tissue culture medium wherein the sulfated polysaccharide or the mixtures of sulfated polysaccharides are substantially free of toxic components and wherein the sulfated polysaccharide has a degree of sulfation greater than 10%.
A method for inhibiting vitrification which comprises growing a species of Pinus or a species of Eucalyptus using a tissue culture media to which an anti-vitrification agent dextran sulfate has been added.
A tissue culture medium comprising growth medium for a species of Pinus and dextran sulfate.
A tissue culture medium comprising growth medium for a species of Eucalyptus and dextran sulfate.
