摘 要 ：菊芋（Helianthus tuberous L.）属菊科向日葵属多年生草本植物，是重要的作物种质资源。国内外对菊芋已开展了生态、经济、能源及育种栽培等研究，近年来胁迫条件对菊芋的影响研究成为新的热点。菊芋是无性繁殖作物，目前对菊芋种质资源的保存主要采取田间圃位的形式，国外已经开展了试管苗保存和超低温保存等研究，而我国尚存在空白。本文着重从菊芋的胁迫耐性响应研究，包括对干旱、盐碱及低温三个不同胁迫条件对田间性状、生理生化、蛋白、分子水平的研究，以及常规保存和离体保存等种质保存研究两个方面进行阐述，并指出目前存在的问题，为菊芋超低温保存和开发利用提供理论依据。

Abstract:Jerusalem artichoke (Helianthus tuberous L.) belonging to Asteraceae family, is a perennial herb. Jerusalem artichoke is an important crop germplasm resource. The researches on its ecological, economy, energy, cultivation and breeding, and the stress responses have been conducted for many years. Jerusalem artichoke is one of asexually propagated crops, and mainly conserved in the filed nursery. The in vitro conservation and cryopreservation method has been tried in the United States Department of Agriculture. However, the relevant research has not been started in China. In this paper, we will summarize the research progress of Jerusalem artichoke germplasm resource and pay more attention on the study of stress response, including research the drought, salinity and low temperature stress on the behavior of the field, physiological and biochemical, protein and molecular level. And the general conservation and In vitro conservation of Jerusalem artichoke, and points out the problems. This will be benefit for the future utilization and cryopreservation in the future.
