Effect of polyamines and polyamine precursors on hyperhydricity in micropropagated apple shoots


Hyperhydricity is a physiological disorder affecting tissue-culture-generated plants. It is associated with excessive hydration and poor lignification. The effects of exogenous polyamines (spermidine and putrescine) and polyamine precursors (arginine and ornithine) were studied on ‘Jonagold’ apple shoots subjected to hyperhydric conditions for one in vitro… (More)
