Abstract

Hyperhydricity is considered as a physiological disorder that can be induced by different stressing conditions. Sucrose metabolism is modified in hyperhydric leaves with a high increase in the activity of both synthesis and catabolic enzymes. The various remedies for preventing hyperhydricity have been proposed are known to bear environmental factors as well as on medium composition. The hyperhydricity of the shoot cultures could be decreased by progressively ventilating the vessels. Many polysaccharide producing Pseudomonas species are also capable of preventing this detrimental condition. The approaches reviewed indicated that it is possible to reduce or control hyperhydricity of in vitro grown plants and thereby facilitating them for successful transfer to soil.
