Cold Storage Period of Bulbs Influences Their Sugar Contents and Post-Storage Growth and Flowering in Lilium Oriental Hybrids

This study was carried out to investigate the changes in internal shoot growth, total and reducing sugar content, plant growth, and flowering characteristics after cold-stored bulbs of Lilium Oriental Hybrids are planted. Bulbs of Lilium Oriental Hybrids ‘Le Rev...

Bulbs of <i>Lilium</i> Oriental Hybrids ‘Le Reve’, ‘Sorbonne’, and ‘Siberia’ were harvested at the end of November, cleaned, treated with fungicides, conditioned for 30 days at 4 °C, and cold-stored for 30 to 120 days at 0 °C. Plant height, fresh and dry weights, leaf numbers and area, chlorophyll content (SPAD index), days to flowering, number of flower buds, and flower diameter were measured when the cut flowers were harvested. In all cultivars, the shoot lengths in the bulbs increased as the storage period increased. As the storage period was extended, the fructose and glucose contents increased, whereas sucrose content decreased. The total sugar content increased during the early storage period and decreased subsequently. Plant height, fresh and dry weights of cut flowers showed a decreasing trend as the storage period increased. Flower diameter generally decreased with increasing storage period but varied among cultivars. These results indicated that more storage carbohydrates in bulbs were consumed as the storage period increased, and thus, the subsequent plant growth and flowering were negatively affected.Jiseon KimWook OhMDPI AGarticlebulb qualitycut flower qualitylow temperature storagesugar contentAgriculture (General)S1-972ENAgriculture, Vol 11, Iss 1080, p 1080 (2021)
