seeds with low doses (0, 5, 10, 15, 20 and 25 Gy) of radioactive cobalt
(60Co) γ-rays, on the germination characteristics as well
as on the root and shoot growth, are investigated. The effects of such
irradiation doses on the relative water content and cell membrane stability
following a water deficit, are also studied. The irradiated seeds kept
their germination speed and capacity in Petri dishes. On Murashige and
Skoog (MS) liquid medium, the dose of 15 Gy induced a significant improvement
(nearly 20%) in root length as compared with the 0 Gy dose. Under glass
house conditions, the root and shoot lengths and dry weights of plants
grown from seeds irradiated with a dose of 15 Gy, are found to be improved
at rates of 19 and 89%, respectively when compared with plants issued
from non-irradiated seeds. The same irradiation dose allowed the plants
subjected to a water deficit to maintain a better water level and a more
stable cell membrane as compared to the control plants.]]>Alarkon, K., L. Bozova and N. Stoeva,1987244043Cengiz, T., U. Bulent, C. Huseyin and C.F. Oncu,200573365367Charbaji, T. and I.
