Intelligent germination incubator on seed germination found that the effect on germination rate: from a constant germination temperature, from 15 °C to 20 °C, the germination rate of Bupleurum seeds increased (significant SX level); temperature continues to rise (25 °C), the germination rate decreased; when the temperature rose to 30 °C, the germination rate continued to decline, significantly lower than the germination rate of 20 °C, SX, GS even without a seed germination. In addition to ZC at 4 constant temperatures, the germination rate of other Bupleurum seeds was below 50%, and GS was even lower than 10%. The results showed that the constant temperature is not conducive to the germination of seeds of Bupleurum (except for ZC), and the high temperature inhibits its germination. Compared with the constant germination temperature, 15 ~ 25 °C or 20 ~ 30 °C temperature treatment, can significantly promote the germination of Bupleurum seeds, SD, SX, GS germination rate in the corresponding constant temperature (high temperature) increased by more than 50%. This shows that Bupleurum seeds are very suitable for germination under variable temperature conditions.
Constant High Temperature Suppression Germination Relief Test: On the 51st day of the intelligent light incubator, the fresh non-emergence seeds in the box at 30°C were divided into 2 groups with 3 replicates (germinated boxes) in each group, and 1 group was still placed in the 30°C box. Germination, the other group transferred to 20-30 °C (30 °C 8h, 20 °C 16h) box germination, the first 72 days statistics seed germination.
The germination characteristics of seeds were studied by intelligent light incubator. For the first time, the response of different germplasms of Bupleurum chinense to germination temperature and the germination performance of seeds under optimum germination temperature were clearly pointed out, and there were significant differences. Therefore, the dormancy or germination characteristics of Bupleurum chinense seed cannot be generalized but is closely related to germplasm.
Pigment And Dye is a colored material that is completely or nearly insoluble in water. In contrast, dyes are typically soluble, at least at some stage in their use. Generally dyes are often organic compounds whereas pigments are often inorganic compounds Dioxide Titanium. Pigments of prehistoric and historic value include ochre, charcoal, and lapis lazuli.
A dye is a colored substance that chemically bonds to the substrate to which it is being applied. This distinguishes Ethylene-Vinyl Acetate dyes from pigments which do not chemically bind to the material they color Black Iron Oxide . Dye is generally applied in an aqueous solution, and may require a mordant to improve the fastness of the dye on the fiber.
Both dyes and pigments are colored, Titanium Dioxide Food Grade because they absorb only some wavelengths of visible light. Dyes are usually soluble in water whereas Sodium Hexametaphosphate pigments are insoluble. Some dyes can be rendered insoluble with the addition of salt to produce a lake pigment.
