Abstract :
ABSTRACT: A field experiment was conducted for two consecutive years to study foliar spray of Feso4 and Znso4 on the growth and floral characteristics Gladiolus variety “Oscar”. The experiment was laid out in a randomized complete block design with three replicates in the field, Varamin Research Center. The evaluated was response and to find out the optimum dose of the same for production of gladiolus variety "Oscar".
an efficient concentration of Feso4 and Znso4 on quality and productivity of gladiolus.
the optimum dose of Feso4 and Znso4 Plants were grown and treated with three levels of 0, 0.5%, and 1% of two micronutrients Feso4 and Znso4 and their various combinations at two- leaf and six-leaf stages. The results disclosed that solutions of Feso4 and Znso4 significantly affected plant growth and floral characteristics of gladiolus. Higher conttents of both Feso4 and Znso4 speed the plant growth and increased flowering characteristics. Application of 1 % Feso4 accelerated flowering earlier than Znso4, as well as elongated days to spike emergence (21.49 days) and first florets opening (38.28). The results showed that 2% of both Feso4 and Znso4 solutions and their mixture delayed the days from basal floret opening and number of floret at a time. The flowering properties like plant height (83.47 cm), length of spike (66.03cm), number of leaves (9.52 /plant) floret number (11.55/spike), diameter of floret (8.53cm) wrere significantly different other treatments when a mixed solution of 2% Feso4 and Znso4 was applied. It is concluded that no application of micronutrients on gladiolus ornamental at the commercial scale will produce poor quality of vegetative growth and low number of florets. However, It is suggested that micronutrients play a vital role on the growth and development of gladiolus plants, because of its stimulatory and catalytic effects on flower yield and metabolic processes.
