摘要Paris polyphylla var. yunnanensis is a rhizomatous geophyte in high demand for industrial and medicinal purposes. It grows very slowly, and thus, rhizome cutting is a promising propagation technique. However, whether and how polyapical shoots can be artificially produced with rhizomes is unclear. This study reported that a P. polyphylla rhizome mainly sprouts one shoot but could occasionally grow polyapical shoots. Application of phytohormones, including auxins, cytokinins, abscisic acids and gibberellins on P. polyphylla rhizomes showed that GA3 could break dormancy in two weeks and induced polyapical shoots at a rate of 100 %. The apical shoot number per GA3-treated rhizome reached 7.2. The GA3-induced occurrence of polyapical shoots derived from the repetitive de novo formation of apical buds. GA3 application changed endogenous auxin, cytokinin or ABA concentrations slightly or not at all but dramatically increased endogenous GA3 and GA1 levels in rhizomes. Transcriptional profiling showed there were few shared differentially expressed genes and significant differences in the expression patterns of hormone-related genes between rhizomes with mono- and polyapical shoots. These results suggest that P. polyphylla has the genetic potential to produce polyapical shoots. GA3 treatment can quickly break dormancy and strongly induce polyapical shoots in this species, providing an efficient rhizome cutting technique for P. polyphylla propagation.
