Regulation of callus status and cell-suspending culture in naked seed oat (Avena nuda).
The original calli were obtained by inducing culture of mature embryos of naked seed oat on N6 medium. The original calli were white-colored tumor forms, soft outside and hard inside. These kinds of calli are easy to differentiate into plantlets, and they are not the friable type. Friable embryogenic calli could be obtained by cycled regulated culture on IM1-IM4 medium for 7-8 months from the original calli. They became vigorous, lightish yellow in color, with small grainy forms. Well-separated and fast-growing suspending cell lines have been obtained from the above-mentioned embryogenic calli in the liquid medium. Regenerated plants have been obtained for this kind of suspension line by culturing on the medium for differentiation. The surviving percentage for such plantlets was over 95% after planting in the soil.
