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.
