| 为筛选适合广西种植的旱藕品种，比较了广西本地和引进的5 个旱藕品种在农艺性状和营养品质上的差异。结果表明，兴芋2 号、兴芋3 号的株高显著高于其他3 个本地品种，兴芋2 号、兴芋3 号、马山旱藕的茎径、分蘖数、叶长和叶宽显著高于其他2 个本地品种，兴芋3 号、兴芋2 号、马山旱藕、平果旱藕间的茎节数和叶片数没有显著差异。外地品种主要农艺性状相对较稳定，本地品种各农艺性状变异程度均较大。兴芋3 号产量最高，比兴芋2 号增产10%，两者产量均极显著高于其他本地旱藕品种。旱藕产量与株高、分孽数、叶长和叶宽显著相关。外地旱藕品种脂肪含量没有差异，每100 g 兴芋3 号淀粉含量和黄酮含量比兴芋2号分别增加0.3 g、3.2 mg。兴芋3 号和兴芋2 号具有较好的生长势、丰产性和适应性，两者均适合在广西大面积推广种植。 |
| 英文摘要: |
| In order to screen canna varieties suitable for planting in Guangxi，the agronomic traits and nutritional quality of local and introduced canna varieties were compared. The results showed that the plant height of‘ Xingyu 2’and‘ Xingyu 3’ were significantly higher than that of other three local canna varieties. The stem diameter，number of tiller，leaf length and leaf width of‘ Xingyu 2’，‘Xingyu 3’，‘Mashan canna’ were significantly higher than that of other two local canna varieties. There was no significant difference in stem node number and leaf number among‘Xingyu 3’，‘Xingyu 2’，‘MaShan canna’and‘ Pingguo canna’. The major agronomic traits of exotic varieties were relatively stable and the agronomic trait variation of local varieties was higher than that of exotic varieties. The yield of‘ Xingyu 3’ was the highest，which increased by 10% compared with‘ Xingyu 2’，and their yield were significantlyhigher than that of other local canna varieties. The yield of canna was significantly correlated with plant height，numberof tiller，leaf length，and leaf width. The fat content of exotic varieties had no variation. The starch and flavonoids contentof‘ Xingyu 3’ increased by 0.3 g/100g，3.2 mg/100g respectively compared with‘ Xingyu 2’.‘ Xingyu 3’ and‘ Xingyu 2’ were suitable for planting in Guangxi with good growth potential，high yield and adaptability. |
