The objective of this investigation was to measure the growth and flower response of carnation plants to the application of various levels (0, 2, 4 g.l-1) of amino acid (Terra-Sorb and Triamin) and chemical fertilization (Turo-fort and Nami), three times during the growing period, as a possible program for the production of quality plants through fertilization. Carnations (Dianthus chinensis x barbatus) were pot-grown in an unheated green-net greenhouse. The results showed that plants sprayed with fertilizer solutions showed a significant increase in the growth parameters. The results also showed that the treatments stimulated the flowering parameters (number of inflorescences per plant, inflorescences diameter, flowering date, and inflorescences dry mass) and increased the number, diameter, and dry mass of inflorescences per plant, when compared to the untreated plants (control). The a, b, and total chlorophyll (a+b), carotenoid and anthocyanin content, gas exchange measurements and leaf mineral content (P, N, K, and Total carbohydrates) were significantly increased compared to the control, as a result of the application of different levels of the chemical foliar fertilizer spraying solutions (Turo-fort and Nami). Carnations plants with foliar fertilizer solution application had higher leaf gas exchange (stomatal conductance (gs), transpiration rate (E), photosynthetic rate (PN) and plant intercellular CO2 concentration (Ci)).
