The effect of gamma irradiation on the lysine content of plants

  • 1. Agrartudomanyi Egyetem, Goedoelloe (Hungary)

Description

It has been proved by studies on the physiological effect of ionizing irradiation that in plant metabolism important changes take place. From the endosperm of seven-day-old seedlings 14C-L-Lysine is transported faster to organs, especially to shoots and its incorporation into protein is also more intensive. The animation of the growth of roots and shoots can be observed on 14-day-old plants grown in water culture. In sand culture a surplus in dry weight can be experienced after 56 days for maize, under the influence of 100 rad. Two soybean varieties (Merit, Clay) responded different to irradiation. The dry weight of the Merit variety was increased significantly by 500 and 1000 rad, whereas that of the Clay variety decreased or did not change significantly. The lysine content of plants changes in the function of growth. In the case of the two maize varieties (Szegedi sarga, KSC 360) treatments with 1000 and 5000 rad resulted in an essential surplus of the total lysine content (46.25 and 31.21%, respectively). The total lysine content of the Merit variety has been increased by about 23.9% and 20.92%, respectively. 5000 rad treatment resulted in a negative correlation (-0.77) in the shoots. The total lysine content of the Clay plants was lower than that of the control. Under the influence of 500 and 1000 rad treatments the total lysine content of the shoots of the Merit variety grown in fields increased to a lesser extent (16.82 and 3.19 respectively) than that of plants grown in a climate room.
