摘要：The poplar is a model system for research on wood plant biology. An establishment of an efficient poplar regeneration system (PRS) plays a key role in the molecular breeding of wood plants. At present, most established PRSs are based on orthogonal experiments of previous research data. However, such an experiment is complex, time-consuming, and inefficient for various poplar subspecies. Therefore, an efficient solution to the establishment of PRSs is urgent. In this study, the triploid white poplar (Populus tomentosa 'YiXianCiZhu B385 ') was used as an experimental material to establish a leaf-based regeneration system. Firstly, different concentrations of hormones were added into the medium for the differentiation, stretching, and rooting of leaves, and the electrical conductivity of the medium was measured by a conductivity meter. Secondly, the optimal hormone concentrations for differentiation, stretching, and rooting were obtained by wavelet analysis. Finally, the Electrical Signal Conduction Characterization Model (ESCCM) of different hormone concentrations in the differentiation, stretching, and rooting of poplars was established. The result showed that the ESCCM improves the efficiency of PRSs, and this provides new insight and theory in molecular breeding. The ESCCM also provides the possibility of an automated establishment of a PRS.
