Effect of the Egyptian Propolis on the bioactive compounds content in tomato plants

الملخص EN

Propolis is an organic substance that considered a biostimulant agent and plays a vital role in increasing bioactive compounds content in plants.

The study investigated the properties of two different kinds of propolis i.

e.

, Egyptian and Chinese propolis.

The physical and chemical analyses results of the Egyptian propolis showed that it contain 253.703 mgGAE/g total phenolic compound, 76.766 mgQE/g total flavonoid compound and 5.417 g/100g total alkaloid.

Also, the effect of five concentrations of aqueous extract of the Egyptian propolis was studied as a foliar spray on tomato plants, which were (1, 2, 10, 20, 100 mg propolis ml^-1).

Tomato plants treated with propolis (100 mg/ml) showed a significant effect in antioxidant content and other bioactive compounds compared to control plants.
