摘要

The growth indexes and sugar composition of different cultivars of Helianthus tuberosus Linn. planted in Hainan district were compared and analyzed,and H. tuberosus cultivars suitable for planting in Hainan district were screened out. The results show that with prolonging of time, plant height, stem diameter,dry weight of above?ground part per plant, dry weight of root per plant, and total dry weight per plant of six cultivars of H. tuberosus generally increase gradually, while changes of root length show different trends. On October 26(mature stage),plant height and stem diameter of'Taiyu No.1'are the highest,root length,and yield,fresh weight per plant and moisture content of tuber and stem of'Nanyu No. 9'are the highest, dry weight of above?ground part per plant, dry weight of tuber per plant, and total dry weight per plant of'Nanyu No. 1'are the highest,and dry weight of root per plant of'Qingyu No. 2'is the highest. With prolonging of time, change ranges of soluble sugar content in leaves of six cultivars of H. tuberosus are relatively small, while soluble sugar content in stems generally decreases gradually. Changes of reducing sugar content in leaves and stems of six cultivars of H. tuberosus show various trends. On October 26,soluble sugar content in leaves of'Nanyu No. 9'is the highest,there is no significant difference in reducing sugar content in leaves among six cultivars of H. tuberosus, and contents of soluble sugar and reducing sugar in stems of 'Taiyu No. 1'are the highest; soluble sugar content in tubers of 'Nanyu No. 1','Nanyu No. 9','Taiyu No. 1', and 'Taiyu No. 2'is relatively high,and reducing sugar content in tubers of 'Qingyu No. 2', 'Taiyu No. 2', and 'Taiyu No. 3'is relatively high. With prolonging of time,fructose content in leaves and stems of'Nanyu No.1','Nanyu No. 9',and 'Qingyu No. 2'generally increases gradually, while that in leaves and stems of 'Taiyu No. 1','Taiyu No. 2', and 'Taiyu No. 3'decreases firstly and then increases; glucose content in leaves of six cultivars of H. tuberosus generally increases gradually, while that in stems generally decreases firstly and then increases; changes of sucrose content in leaves and stems of six cultivars of H. tuberosus show different trends. Overall, there is no significant difference in contents of 1?kestose, nystose,and 1F?fructofuranosylnystose in leaves and stems of six cultivars of H. tuberosus at the same time. The comprehensive result shows that cultivars of H. tuberosus suitable for planting in Hainan district are 'Nanyu No. 1'and 'Nanyu No. 9'.%对种植于海南地区的不同菊芋(Helianthus tuberosus Linn.)品种的生长指标和糖分组成进行比较和分析,并筛选出适宜海南地区种植的菊芋品种.结果表明:随着时间的推移,6个菊芋品种的株高、茎粗、单株地上部干质量、单株根干质量及单株总干质量总体上呈逐渐升高的趋势,而根长的变化趋势各异.10月26日(成熟期),'泰芋1号'('Taiyu No.1')的株高和茎粗最高,'南芋9号'('Nanyu No.9')的根长以及块茎和茎干的产量、单株鲜质量和含水率最高,'南芋1号'('Nanyu No. 1')的单株地上部干质量、单株块茎干质量及单株总干质量最高,'青芋2号'('Qingyu No. 2')的单株根干质量最高.随着时间的推移,6个菊芋品种叶片中可溶性糖含量的变幅相对较小,而茎干中可溶性糖含量则总体上呈逐渐降低的趋势;6个菊芋品种叶片和茎干中还原糖含量的变化趋势各异.10月26日,'南芋9号'叶片中可溶性糖含量最高,6个菊芋品种间叶片中还原糖含量差异不显著,'泰芋1号'茎干中可溶性糖和还原糖含量最高;'南芋1号'、'南芋9号'、'泰芋1号'和'泰芋2号'('Taiyu No. 2')块茎中可溶性糖含量较高,'青芋2号'、'泰芋2号'和'泰芋3号'('Taiyu No. 3')块茎中还原糖含量较高.随着时间的推移,'南芋1号'、'南芋9号'和'青芋2号'叶片和茎干中果糖含量总体上呈逐渐升高的趋势,'泰芋1号'、'泰芋2号'和'泰芋3号'叶片和茎干中果糖含量均呈先降低后升高的趋势;6个菊芋品种叶片中葡萄糖含量总体上呈逐渐升高的趋势,而茎干中葡萄糖含量总体上呈先降低后升高的趋势;6个菊芋品种叶片和茎干中蔗糖含量的变化趋势各异.总体上看,同一时期6个菊芋品种间叶片和茎干中蔗果三糖、蔗果四糖和蔗果五塘含量的差异均不显著.综合研究结果显示:适宜在海南地区种植的菊芋品种为'南芋1号'和'南芋9号'.
