| Abstract | ||||
| Gamma radiation and polyethylene glycol (PEG) are widely used in various fields of research to induce stress and study their effects on plants. In this investigation the morphological characterization, cellular, and extracellular structure were studied of wheat cv. Sids 13. Gamma radiation doses 50 and 100 Gy were affected on shoot and root length negatively. Where caused decreasing in both shoot and root length with 3 cm, 8 cm; and 2 cm, 5 cm; respectively. While polyethylene glycol concentrations 10, 15, and 20% induced decreasing in shoot and root length with (8, 11 and 13cm) and (5, 7 and 8.5 cm) respectively. The combined effect of gamma ray doses and PEG also caused severe decreasing in both shoot and root length with (10, 12 and 15cm) and (5, 7 and 8.5 cm) respectively. Gamma radiation and PEG also affect the cellular and ultracellular structure of wheat. These effects investigated using various microscopy techniques, such as light microscopy, transmission electron microscopy, and scanning electron microscopy. These techniques reveal changes in cell size, cell wall thickness, organelle morphology, and other cellular structures. This study aims to investigate the effect of some radiation doses, different PEG concentrations and the combined effect on morphological and cellular changes in wheat variety Sids 13. | ||||
