项目摘要

1.Dormancy and its breaking in Hosta(1)Hosta plants were induced to grow continuously by transfer to both 16-hour daylength and 27℃ regardless of the growth stage. When the growth of main axes weakened for bolting, some lateral buds sprouted and developed into lateral shoots. In such a case, H.sieboldii (H.albomarginata) developed several vigorous lateral shoots per plant, but H.sieboldiana few lateral shoots. After chilling H.sieboldiana developed a few vigorous lateral shoots.(2)Dormancy in Hosta was readily induced by exposure to 8-hour daylength, regardless of the growth stage.(3)The lateral buds in H.sieboldiana had deep paradormancy while the main axes maintained vegetative growth., but those in H.sieboldil had shallow or almost no one.2.Breaking bud dormancy of Polygonatum and Smilacina rhizomes(1)P.macranthum rhizomes had very deep dormancy in November or earlier, and P.odoratum ones deep dormancy in October or earlier. Their dormancy was broken by the treatment for about 90 days at 5 However, the dormancy in July or earlier was hardly broken by such a treatment.(2)The dormancy of S japonica rhizomes was also broken by the 5℃ treatment, but the dormancy in October or earlier failed to be broken by such a treatment.3.In vitro proliferation in HostaA great many adventitious shoots were produced by in vitro culturing young seedlings in Hosta. Those microshoots were maintained in vitro for a long term and efficiently propagated. Acclimatization of the plantlets were achieved in two weeks with a high survival rate.4.Applications of the results obtained(1)Establishing the technical system for a year-round culture in Hosta.(2)Establishing some extreme forcing-culture in Polygonatum and Smilacina.(3)Establishing efficient proliferation by micropropagation in Hosta

1.炎症及其在昆达植物中的破裂及其破裂是通过转移到16小时的日长度和27℃的27°诱导的。当主轴的生长减弱以用于螺栓时，一些侧芽发芽并发展为侧芽。在这种情况下，H.Sieboldii（H.Albomarginata）每植物产生了几种剧烈的侧芽，但H.Sieboldiana几乎没有侧芽。在寒冷之后，H.Sieboldiana发生了一些剧烈的横向拍摄。（2）hosta的休眠很容易通过暴露于8小时的日间长度，无论增长阶段如何。（3）H.Sieboldiana中的横向芽具有深层的壁式，而主要的轴是在植物性的植物中保持植物性成长。 Smilacina Rhizomes（1）在11月或更早的时候，巨大的根瘤菌患有非常深的休眠，并且十月或更早的p.odoratum p.odoratum。但是，这种治疗的治疗方法因治疗约为90天而破坏了大约90天，这种治疗的休眠几乎不会被打破。（2）S Japonica根茎的休眠也因5 r疗法而被打破，10月或更早的休息时间，但是这种治疗方法未能通过这种治疗方法破坏。这些微动物长期维持体外并有效地传播。在两周内以高存活率实现了植物的适应性。4。获得的结果的应用（1）建立在昆达的全年培养的技术系统。（2）在多边形和smilacina中建立一些极端的强迫文化。（3）（3）通过在Hosta在Hosta中建立有效的繁殖，以建立Hosta hosta hosta host hosta host hosta host hosta cultive
