Effect of Microwave on Seed Germination and Growth Rate in Some Genera Fabaceae Trees in Antoniades Garden (B) Delonix regia and Albizzia julibrissin

Abstract

Microwaves used in this study were generated from a microwave oven Model-Mo6T, single phase, 220 V., 50 Hs., 1.3 kW output at a frequency of 2450 MHz. Dry seeds were exposed to short waves from microwave on the first of February, 2019 and 2020 in both seasons, respectively. 315 seeds per genus were divided into 7 groups per specie (7groups* 45 seeds per treatment) and each treatment was put in a bag. The seeds have been exposed to microwave radiation for 0s (control), 5s, 10s, 15s, the 20s, 25s and 30s in the Delonix regia and Albizzia julibrissin in the first and second seasons respectively. Groups of 45 seeds were subjected to each microwave treatment, for chosen exposure times and analogous groups were used as control. The seeds were cultured in trays (50eye/ tray), with 45 seeds in each tray, on a mixture of peat moss and sand at a ratio of 1:1 (v/v). The trays were watered daily. a mixture and chemical constituents th
