| Abstract:
Embryogenic calli were obtained from the eight-week-old abortive embryo of peach (Prunus persica (L.) Batsh) cultivar "Sunagowase" cultured in MT basal medium. Intact viable protoplasts were isolated from embryogenic calli after several subcultures. After protoplast purification, a high protoplast yield (2.47 x 106/g-1FW) was obtained. The purificatory protoplasts were incubated in PC-1 medium without growth hormone. The first cell division was observed 5–7 days after the culture and a high plating density (about 26.4%) was obtained. The colonies were transferred onto PC-2 medium 1 month later and calli were then observed. It was indicated that the low melting point agarose (LMP) embedding culture is more favourable for peach protoplast compared with the thin liquid layer culture. | |
