Description

Inorganic salts in Murashige Skoog(MS) tissue culture medium prolonged vase life of gladiolus, rose and carnation cut flowers when supplemented to holding solution with sugar. Effective major elelment was nitrogen and its optimum level and ratio of NO_3 to NH_4 ion were the same as those of MS medium. Nitrogen seems to take effect through enhancement of protein synthesis activity not through retardation of senescence nor through osmotic effect. Nitrogen effect was limited to species in which sugar took effect for longevity of their cut flowers.
