摘要註:	植生復育為環境友善之綠色復育技術，搭配常應用於提升農作物生長之過氧化鈣及生長激素，可預期提高植生復育成效。研究主要分為兩部分，分(1)水耕試驗。(2)盆栽試驗。在水耕試驗中初步了解過氧化鈣、生物激素 (IAA 與 GA3) 與螯合劑EDTA添加對於向日葵植體生長之情形，從生長情形了解生長激素之添加有效提升向日葵植體之生長情形，但於水耕中同時添加生長激素及螯合劑EDTA之組別生長情形不佳，表示若於水體中無持續提供植體所需之養分，添加生長激素仍無法抵抗EDTA所帶來之毒性，而過氧化鈣於水體中釋放氧氣速率過快，於本研究中並無法應用於水耕試驗中。而盆栽試驗探討不同濃度生長激素對於向日葵成長情形影響研究中，GA3 10-8M效果為最佳，其次為IAA 10-8M，IAA 10-12M則係最差，而由不同部位重金屬累積分析實驗來看，GA3作用部位為植體葉片部分，其作用將土壤中養分輸送至植體葉片，導致GA3組別TF值為2.329優於控制組之1.845表示經GA3生長激素之添加與螯合劑有同樣使TF值提高之效果，且較螯合劑友善於向日葵植體，而探討植生降解(Phytoattenuation)之能力研究中，一個月之實驗期內分為三階段各為10天，其每一階段土壤重金屬濃度皆有持續往下降之趨勢，控制組由原先之31.63 mg/kg降解至23.96 mg/kg，GA3組由32.09 mg/kg降解至23.04 mg/kg，EDTA組由30.65 mg/kg降解至25.93 mg/kg，可知在向日葵於花苞初形成至開花這階段為其生長最快速之成長期，在此階段因其快速往上輸送養分導致其植體快速累積重金屬，於此階段累積重金屬之速度也較直接種植已開花植體成效較高。本研究顯示添加生長激素對於植物萃取具提升之效益，且搭配花苞初形成之向日葵植體可帶來更佳之整治效果。 This study included metal reduction investigation within hydroponic experiments and pot experiment. Hydroponic experiments preliminary understanding of calcium peroxide, plant growth regulators (IAA and GA3)and EDTA in the experiment of sunflower explants growth, add plant growth regulators from the growth situation effectively enhance the growing of sunflowers, but add hydroponics both growth hormone and groups of the chelator EDTA the growing poor, expressed in water bodies without continuing to provide the necessary nutrients explants add growth hormone still can not resist the toxicity of EDTA. Brought peroxide calcium release oxygen in water bodies rate too fast, and in this study can not be used in hydroponic experiments. Phytoremediation, a green technology developed to extract heavy metals from polluted soils, has drawn a great attention due to cost-effectiveness and aesthetically pleasing nature. The aim of this research intends to assess the potential of bioenergy plant sunflower to remediation soil polluted with a mixture of heavy metals. Pot experiment to explore different concentrations of plant growth regulators for sunflower growth scenario influence of GA3 10-8M was the best, followed by IAA 10-8M>GA3 10-12M> IAA 10-12M>Control. Heavy metal accumulation in different parts of the analysis of experiments to GA3 site of action of the blade portion of the explants, and its role in soil nutrient transport to the leaves of explants lead the GA3 TF value 2.329 better than the control TF value 1.845, GA3 plant growth regulators add chelating agents have the same make TF value to improve the effect, and friendly sunflower explants. Phytoattenuation is a novel green remediation concept, has been successfully demonstrated while employing sunflower and plant growth regulator gibberellic acid GA3 and chelator EDTA, one-month experimental period is divided into three stages, each stage for 10 days, at every stage of its soil the heavy metal concentration continued to trend of decline in the control group from the original of 31.63 mg / kg degraded to 23.96 mg / kg, GA3 group from the original of 32.09 mg / kg degraded to 23.04 mg / kg, EDTA group previously had 30.65 mg / kg degradation to 25.93 mg / kg, to be seen early in sunflower bud formation to flowering at this stage of its growth is most rapid in the growth stage. at this stage because of its rapid upward transport of nutrients cause its also in explants rapid accumulation of heavy metals in this stage cumulative speed of heavy metals also more direct planting flowering explants effectiveness. This study shows that add growth hormone to enhance the effectiveness of plant extracts with, and with the bud early formation of sunflower explants may bring better regulation effect, and harvest recovery explants as biosorbent to remove Cu, Zn and Pb from aqueous solutions.
