this research was aimed to investgate the effect of light quality on micropropagation of pear rootstock oh×f333. first, single nodes explants were cultured in modified ql medium containing ba at four levels (0, 0.5, 1, and 2 mg/l-1) and iaa at three levels (0, 0.1, and 1 mg/l-1) and were evaluated for shoot proliferation. then, plantlets subcultured in modified ql medium containing 1 mg/l-1 ba ...
