| 中文摘要 | Adventitious buds were induced from organogenic callus derived from mature zygotic embryos of three lines (E-311, E-440, and E-822) of loblolly pine (Pinus taeda L.) within 27 weeks of culture. The influence of cytokinins, silver nitrate, and low-temperature treatment on the differentiation of adventitious buds was analyzed. Elongation of adventitious buds was achieved on TE medium supplemented with 0.5 mg/l indole-3-butyric acid (IBA) and 1 mg/l 6-benzyladenine (BA). After adventitious shoots had rooted on TE medium supplemented with 0.5 mg/l IBA, 2 mg/l BA, and 0.5 mg/l gibberellic acid, 498 regenerated plantlets were transferred to a perlite:peatmoss:vermiculite (1:1:1) soil mixture; 351 of these survived in the field. Total DNA was extracted from 21 regenerated plantlets randomly chosen from the 151 regenerated plantlets of line E-822. Random amplified polymorphic DNA (RAPD) analysis using 80 arbitrary oligonucleotide 10-mers showed that 21 primers gave 107 clear reproducible bands, with the amplification products being monomorphic for all of the plantlets of line E-822 tested. A total of 2,247 bands obtained from these studies exhibited no aberration in RAPD banding patterns among the tested plantlets. These results suggest that somatic organogenesis can be used for clonal micropropagation of some lines of loblolly pine without the fear of the appearance of unwanted somaclonal variants. |
