The application discloses a kind of Pterocarpus stem cell culture methods.The culture method includes the following steps: (1) stem cell maintenance factor composition and temperature-sensitive liposome are added to hydrogel precursor solution to be frozen into shape and prepare porous three-dimensional scaffold precursor;After the porous three-dimensional scaffold precursor is crosslinked and solidified, three-dimensional biomimetic niche scaffold is prepared;(2) the explant of Pterocarpus is inoculated in three-dimensional biomimetic niche scaffold and is induced to culture and obtains the stem cell of Pterocarpus plant induced to form;(3) the stem cell of Pterocarpus plant induced to form is taken out, then undifferentiated Pterocarpus plant stem cell mass is filtered and screened by flow cytometry;(4) Pterocarpus plant stem cell mass is placed in liquid proliferation medium and is suspended in culture on shaker, and obtains the stem cell of Pterocarpus plant after proliferation;(5) the stem cell of Pterocarpus plant after proliferation is transferred to production culture medium and is dark culture, and secondary metabolite accumulation is induced.

The invention discloses a growth-promoting bacterial fertilizer for pandan leaves and application of the growth-promoting bacterial fertilizer, and relates to the technical field of biology. Active components of the growth-promoting bacterial fertilizer for the pandan leaves comprise a microorganism combination, the microbial composition comprises bacillus altitudinis, bacillus megatherium, trichoderma longibrachiatum and aspergillus parasuis. Through the synergistic effect of the four strains, the growth-promoting bacterial fertilizer can effectively improve the soil environment of the saline-alkali soil, reduce the pH value of the soil and improve the enzyme activity of the soil and the nutrient effectiveness of the soil; meanwhile, growth and development of pandan leaves can be remarkably promoted, and plant height, stem diameter, fresh weight of single plant and acre yield are increased; the quality of pandan leaves can be improved, and the content of a characteristic aroma substance 2-acetyl-1-pyrroline is increased. The growth-promoting bacterial fertilizer is simple in preparation process, relatively low in cost, environment-friendly and particularly suitable for popularization and application in planting of pandan leaves in saline-alkali soil, and has important agricultural application value and market prospect.

The invention discloses a pterocarpus santalinus heartwood extract, a preparation method thereof and application of the pterocarpus santalinus heartwood extract in preparation of products with an activation effect on mitochondrial functions. The preparation method of the red sandalwood heartwood extract comprises the following steps: (1) extracting red sandalwood heartwood with a solvent, separating an extracting solution, and concentrating and drying the extracting solution to obtain red sandalwood heartwood extract; (2) adding water into the red sandalwood heartwood extract for suspension to obtain a red sandalwood heartwood extract suspension; adding an organic solvent into the red sandalwood heartwood extract suspension for extraction, and concentrating and drying an organic solvent extracting solution to obtain an organic solvent extract; and taking an organic solvent extract to obtain the red sandalwood heartwood extract. Researches show that the red sandalwood heartwood extract prepared by the method can significantly activate mitochondrial functions, enable ATP release level to recover to high-level active substances, and delay cell aging, so that skin aging can be effectively reduced when the red sandalwood heartwood extract is used as a skin care product.

This invention provides a tissue culture medium for *Pandanus tectorius* leaves and a method for rapid propagation through tissue culture. Using young lateral buds of *Pandanus tectorius* leaves as explants is preferable due to its low contamination rate, rapid initiation of proliferation, and superior surface sterilization method, resulting in low contamination and browning. Adding 0-0.1 mg TDZ and 1-3 mg 6-BA to MS medium for *Pandanus tectorius* leaf bud induction culture rapidly initiates proliferation. Subculture with NAA and 6-BA in MS medium effectively improves the proliferation rate, producing robust and rapidly growing seedlings that effectively balance callus amplification and bud propagation. Adding NAA to 1 / 2 MS medium for *Pandanus tectorius* leaf rooting culture results in high rooting efficiency and good root growth and development. This allows for rapid and large-scale propagation of *Pandanus tectorius* leaf tissue culture seedlings, enabling large-scale production, promoting the vigorous development of *Pandanus tectorius* leaf cultivation, and stimulating the development of related industries such as pharmaceuticals, health foods, and ornamental flowers based on *Pandanus tectorius* leaf raw materials.
