Abstract:
Lilium×formolongi tissue culture bulblets were used as the test materials,plant tissue culture technology was used to investigate the effects of different concentrations of exogenous riboflavin treatment on the growth of Lilium×formolongi tissue-cultured seedlings,and the effects of different riboflavin concentrations on the growth and flowering of transplanted Lilium×formolongi tissue culture seedlings.Additionally,the changes in different plant hormone levels in the leaves of transplanted lily tissue culture seedlings under different riboflavin stress treatments at various time points were measured,in order to provide a reference for the application of riboflavin in the flowering process of different lily varieties.The results showed that low-concentration (0.1 mmmol·L-1) riboflavin treatment promoted the growth of Lilium×formolongi tissue culture seedlings,while high-concentration (0.5 mmmol·L-1) treatment inhibited their growth.2.0 mmmol·L-1 riboflavin treatment had the most significant effect on promoting the height,number of nodes,and number of leaves of transplanted lily plants.Compared with the control,riboflavin treatment significantly increased the number of flowering plants,the number of plants that had already flowered at high concentrations (2.0 mmmol·L-1) and in the vegetative stage without buds decreased significantly with increasing riboflavin concentration.Exogenous riboflavin treatment at different concentrations significantly promoted the accumulation of GA3,ABA,and IAA in the leaves of Lilium×formolongi.However,the response time of riboflavin to the accumulation of different plant hormones varied.Low-concentration riboflavin treatment at 12 hours promoted the accumulation of ZT.Therefore,2.0 mmmol·L-1 riboflavin treatment could effectively promote the growth and flowering of Lilium×formolongi.
