Abstract

Two field experiments were carried out during two successive seasons of 2008/09 and 2009/10 for evaluating the response of gladiolus plant (Gladiolus gandavensis cv.Rosesupreme) to four concentrations ofamino acid "tryptophan" at 0.00, 50, 100 and 200 ppm as pre-soaking of corms for 24 hr and four rates of mineral fertilization NPK (19:19:19) at 0.00, 0.25, 0.50 and1.0%  at three times as foliar spray. The obtained data showed that pre-soaking of gladiolus corms with tryptophan alone and/or in combination with different rates of mineral NPK, stimulated the vegetative growth characteristics, flowering parameters and production of corms and cormels. The best results of  studied parameters were obtained by using 200 ppm of tryptophan treatment with 0.50 and/or l.0% foliar fertilization NPK (19:19:19). Moreover, the results indicated that amino acid "tryptophan" at 200 ppm with mineral fertilization at 1.0% gave the highest values of chemical composition parameters( the total chlorophyll (a+b), mineral contents of leaves and total carbohydrates in the new corms).
