| Abstract | ||
| Gladiolus grandiflorus cv., “Advance Red” is an attractive flower to Egyptian and Arab tastes. It is a distinctive cut flower and is also grown in gardens and parks for the beauty of its flowers. Gladiolus may be exposed to alkaline soil stress in most Egyptian soils. To achieve environmentally friendly and safe feeding programs without resorting to chemical fertilization, which causes soil pollution with heavy metals with long-term residual effects. Therefore, the experiment aimed to use growth stimulants with both salicylic and ascorbic acids (Vitamin C) whether by spraying, soaking, adding to the soil through irrigation, or combining them, with the aim of improving vegetative growth and flower quality and achieving high corm production with high marketable qualities. Both ascorbic and salicylic acid are growth promoters that are naturally produced within plants in general. As their concentration increases as a result of adding them as growth stimulants, their biological effectiveness increases, as they act as antioxidants, stimulate the production of enzymes and proteins, aid in the absorption of nutrients from the soil, aid in cell division and elongation, and inhibit the production of free radicals. The treatment of soil drench with acetylsalicylic acid 96mg/l and ascorbic acid with 100 mg/l respectively, achieved the best results in all cases, followed by the treatment of 96 mg/L acetylsalicylic acid + 100 mg/L ascorbi acid as a foliar spray on the vegetative growth of the plant compared to the control or untreated plants, which gave the lowest values. | ||
