Description

Ionizing radiation technology and in particular gamma radiation is developing as a useful treatment in crop production. Gamma rays cause different physiological and morphological responses in cells and tissues that appear as an increase in germination speed, germination capacity and growth of the leaves (Amjad and Anjum 2007). Several reports on the stimulatory affects on plant growth when exposed to irradiation techniques with radioactive rays at low doses are available (Charbaji and Nabulsi 1999; Moussa 2006). Seed treatment with low doses of gamma rays resulted in a significant increase in germination traits, plant vigor and yield attributes of wheat (Melki and Marouani 2010). High doses of gamma radiation produced deleterious effects, such as poor growth (Amjad, and Anjum 2007). Seedling establishment is a critical stage in the plant life cycle that is the result of successful germination (Liu et al. 2008).
