The effect of γ ray and early blight fungitoxin on the growth of tomato calli

Calli derived from tomato leaves were treated with different γ ray doses and cul-tured in medium with and without early blight fungitoxin.The experiment indicated that γ rayhad obvious influence on the growth of tomato calli,with a stronger inhibition at 3000 rad dose.The fungitoxin could be used as selection pressure in the screening of disease resistant mutant.

Calli derived from tomato leaves were treated with different 7 ray doses and cultured in medium with and without early blight fungitoxin. The experiment indicated that 7 ray had obvious influence on the growth of tomato calli, with a stronger inhibition at 3000 rad dose. The fungitoxin could be used as selection pressure in the screening of disease resistant mutant.
