DESTRUCTIVE PROCESSES IN TISSUES OF CUT L ISIANTHUS FLOWER IN WATER AND PROTECTIVE SOLUTION

Destructive processes in the crown cells of the cut lisianthus flower in water develop within five days. Appearance of visual signs of senes cence intimately correlates with changes in the membrane permeability, water saturation of the flower tissues, and content of abscisic acid and phenolcarbonic acids in the petal cells. The use of a protective s olution containing a bactericide and antioxidant, as well as respirati on substrate permits to stabilize metabolic processes for three - four days and delay degradation of cell structures in the tissues of the l isianthus crown.
