- 摘要:
- 以唐菖蒲切花品种“超级红”为试材，通过比较2013年及2014年NAA和6-BA不同浓度不同处理时间下叶片宽度、花茎长度、切花采收期、新球鲜重和直径，以及新球蔗糖和淀粉含量，发现与蒸馏水处理下最早的切花采收期相比，0.05 mg/L NAA-2 h、0.20 mg/L NAA-2 h、0.05 mg/L NAA-4 h、0.10 mg/L NAA-4 h、0.05 mg/L 6-BA-2 h和0.05 mg/L 6-BA-4 h均有提早作用；与蒸馏水处理下最大新球鲜重和直径相比，0.05 mg/L NAA-4 h 和0.10 mg/L NAA-6 h有增大作用；与蒸馏水处理下最大新球蔗糖和淀粉含量相比，3个浓度的NAA处理2 h以及0.05 mg/L NAA-4 h、0.10 mg/L NAA-4 h对蔗糖含量有增大作用，对淀粉含量有显著增加作用。其中0.05 mg/L NAA-4 h对叶片宽度、花茎长度、新球鲜重和直径、蔗糖含量均具有提高作用，对新球中淀粉含量有显著提高，并可提早切花采收期。相关分析表明，唐菖蒲2~7叶宽与切花采收期存在显著负相关，相关系数均大于0.76。因此在今后的切花生产中可采用0.05 mg/L NAA浸泡种球4 h来提早花期、提高新球品质。
- Abstract:
- Taking Gladiolus hybridus Hort. cv. ‘Advanced Red’ as material，treated by NAA and 6-BA with different concentrations under different times，and then leaf width，stem height，time of cut flower harvesting，as well as diameter size，fresh weight，sucrose content and starch content of daughter corms were compared in Gladiolus hybridus Hort. cv. ‘Advanced Red’ during 2013-2014.The results showed that harvesting time of cut flower could be advanced with 0.05 mg/L NAA-2 hours，0.20 mg/L NAA-2 hours，0.05 mg/L NAA-4 hours，0.10 mg/L NAA-4 hours，0.05 mg/L 6-BA-2 hours and 0.05 mg/L 6-BA-4 hours comparing with the earliest treated by distilled water.As far as quality of daughter corms was concerned the treatments of 0.05 mg/L NAA-4 hours and 0.10 mg/L NAA-6 hours increased diameter size and fresh weight，and 0.05 mg/L NAA-2 hours，0.10 mg/L NAA-2 hours，0.20 mg/L NAA-4 hours，0.05 mg/L NAA-4 hours and 0.10 mg/L NAA-4 hours improved sucrose content and significantly improved starch content in daughter corms comparing with the best treated by distilled water.Among the treatments listed above，0.05 mg/L NAA-4 hours increased the leaf width and stems height，advanced harvesting time of cut flower，enhanced diameter size and fresh weight and increased sucrose content and starch content in daughter corms.There were negative correlations between the leaves width from 2nd to 7th and the harvesting time of cut flower with the correlation coefficients more than 0.76.Therefore,treatment of 0.05 mg/L NAA-4 hours could be used in the future production of cut flower for advancing harvesting time and improving daughter corms quality in Gladiolus hybridus.
