Studying the Influence of Gamma Irradiation on Germination, Vegetative Growth, Photosynthetic pigments and Biochemical Characteristics of Dodonaea viscosa L. Plant

Abstract

Background: Dodonaea viscosa has a fibrous expansion root system and is effective in soil stabilization, which reduces erosion of sand dunes. It has green leaves and deep red capsules, which make it pleasing to see and can also be used as a hedge, specimen plant, or maybe a small patio tree. Gamma rays are considered a source of some desirable mutations in plants. Therefore, the goal was to study the effect of different concentrations of gamma rays to obtain the best concentration that produces the best and strongest specifications for the plant. Results: The results obtained through the study showed that the seeds exposed to the dose of 200 Gy had a positive effect on FGP, GRI, and CVG, while the GI and TSG were affected by the dose of 300 Gy. On the other hand, the seeds treated
with the dose of 400 Gy had a significant effect on most of the vegetative characteristics, photosynthetic pigments, and the activity of PPO and POD isoenzymes. Data analysis of (SDSPAGE) showed a change in protein metabolism, which is one of the functional aspects of the effects of radiation. Conclusions: The results showed that the doses of 200 and 300 Gy had a positive effect on germination characteristics, while the morphological and chemical differences appeared mostly in plants produced from seeds treated with 400 Gy.
