The research was done in the Antoniadis Research Branch of the Agriculture Research Center (ARC), Alexandria, Egypt, over the course of the two succeeding growing seasons of 2019 and 2020. In this study, Delonix regia and Albizzia julibrissin seeds were exposed to microwaves for varying lengths of time in order to increase seed germination, vegetative development, and chemical components. The seeds of each treatment were exposed to microwave radiation for varying lengths of time: 0 seconds (control), 5 seconds, 10 seconds, 15 seconds, 20 seconds, 25 seconds, and 30 seconds in each of the two seasons. Individual seedlings were planted in 20 cm diameter plastic pots that were (1:1) by volume filled with a clay and sand mixture. From the obtained results, it could be concluded that the highest mean in Delonix regia and Albizzia julibrissin plants was scored as a result of exposure time at 5 seconds in both seasons, respectively.
