Abstract :
Tulip is one of the most important flowers to precocity. Treatment of
tulip bulbs with gibberellic acid reduces the forcing period in the greenhouse
resulting energy saving and reduces the tulip’s physiological disorders. This
study carried out about three tulip cultivars includes ‘Lacourtine’, ‘Yokohama’
and ‘Red Favourite’. The results showed that gibberellic acid reduced
significantly stem length, first internode length and duration of precocity
period. Based on the results gibberellic acid at 250 and 500 ppm can be
effective agent in tulip’s precocity.
