Alstroemeria is considered one of the most important and popular ornamental cut flowers in the global flower and plant markets due to its beautiful flowers and wide variety of colors The purpose of this study was to investigate the effects of fulvic acid application on the morphological characteristics of Alstroemeria and to determine its appropriate concentration to improve growth and flowering characteristics as well as absorption of leaf elements. Alstroemeria (Alstroemeria aurea 'Orange Queen') was used for this research. The experiment was conducted based on a completely randomized design using fulvic acid at concentrations of 0, 50, 100, and 200 mg/L at intervals of two weeks for four months with three replications and each replication including two pots. The growth medium of the plants in the greenhouse was a mixture of perlite and cocopeat in a ratio of 1:3. During the period of growth and flowering of plants, a nutrient solution was used in the culture medium. It should be mentioned that in different stages of growth, the temperature of the greenhouse was 10-13/16-18ºC (day/night). At the end of the research, morphological indicators such as leaf number, leaf area, length of flowering stem, number of florets, length, and diameter of florets, and the amount of some elements such as nitrogen, phosphorus, potassium, iron, and zinc were measured. The results showed that the concentration of 100 mg/L of fulvic acid was able to create a significant difference in increasing the number and surface of leaves compared to the control and other concentrations of fulvic acid. Application of all concentrations of fulvic acid caused a significant increase in the number of florets compared to the control. In this study, the concentration of 100 mg/L of fulvic acid increased the flower diameter of Alstroemeria by 1.4 times compared to the control. The maximum floret length was observed in the concentration of 100 mg/L of fulvic acid and the lowest floret length was observed in the control. The concentration of 100 mg/L of fulvic acid could increase the length of the flowering stem by 1.6 times compared to the control. The lowest amount of phosphorus in Alstroemeria leaves was observed in the control and the highest amount of phosphorus was observed in the concentration of 100 mg/L of fulvic acid. In general, using fulvic acid had a positive effect on the measured characteristics. In this research, concentration of 100 mg/L of fulvic acid was more effective than the other concentrations. |
