The invention relates to the technical field of plant tissue culture, in particular to a high-efficiency cultivation method of ixora chinensis tissue culture seedlings based on photoperiod regulation and control, which comprises the following steps: step S1, pretreatment of explants; step S2, primary induction culture; step S3, carrying out subculture multiplication culture; step S4, rooting culture; step S5, seedling hardening and domestication. According to the method, a staged photoperiod regulation and control mode is constructed, the whole process parameters of short photoperiod induction, long photoperiod proliferation, medium and short photoperiod rooting and gradient photoperiod seedling hardening are set in combination with short-day physiological characteristics of the ixora chinensis and growth requirements of different culture stages, and meanwhile, an illumination intensity gradient increasing mode is optimized; the defects that in the prior art, a single photoperiod cannot adapt to the whole culture process, and tissue culture seedlings are damaged due to sudden illumination change are overcome, the browning rate of the explants is controlled, and collaborative optimization of growth in all stages is achieved.

The application discloses a preservative solution for prolonging the life of cut flowers of Impatiens walleriana and a preparation method thereof, and relates to the field of postharvest preservation technology of Impatiens walleriana. The preservative solution is composed of glucose, gibberellin, 8-hydroxyquinoline sulfate, citric acid and deionized water in a specific proportion, wherein the glucose is 3.0% (w / v), the gibberellin is 25 mg / L, the 8-hydroxyquinoline sulfate is 100 mg / L, the citric acid is 80 mg / L, and the balance is deionized water. When the preservative solution is prepared, the gibberellin is first dissolved in anhydrous ethanol to prepare an alcohol-soluble mother liquor, the 8-hydroxyquinoline sulfate is dissolved in deionized water to prepare an aqueous mother liquor, and then the glucose and the citric acid solution are mixed step by step and constant volume is performed, so that a uniform transparent preservative solution is finally prepared. According to the scheme, the cell membrane integrity of the cut flowers of Impatiens walleriana can be effectively maintained, petal browning and water loss can be delayed, the best viewing period and the vase life of the cut flowers can be significantly prolonged, the commodity value can be improved, raw materials are conventional, the process is simple, and the scheme is suitable for large-scale application.
