| Abstract:
The present work was effected with the aim to deeper the knowledge of some physiological aspects relative to seed germination in sour orange. Our objective was to increase polyembryony, rate of germination and seedling uniformity using polyethylene glycol (PEG) 6000. Seeds of different sour orange ecotypes were germinated in climatic cell using three solutions of PEG 6000 with different osmotic potential: - 0.49, -0.90 and -1.10 MPa. The results indicated a different action of PEG on the parameters considered. | |
