Water Lilies (Figure)

【Scientific name】Nymphaea tetragona

Genus of water lilies

[Ecological habits] Most of the species are native to the tropical regions of North Africa and Southeast Asia, and the temperate and frigid regions of Europe and Asia are also distributed in small quantities. Hi light is sufficient, ventilation is good, fertile sandy loam, water quality clean and warm water, suitable water depth is 25 ~ 30m. Cold water lilies can be used in open-air ponds for winters where the roots are not frozen. It sprouts every spring and blooms in summer. After the flower, the fruit sinks into the water. After the ripening, the seeds are cracked and dispersed. Float first and then sink into the water. The stems and leaves of the winter are withered. Perennial herbaceous flowers for aquatic use.

[Cultivation and management] Generally, it is propagated using the ramets method. Before and after Ching Ming, the rhizomes are taken from the soil and cut into pieces of about 10 cm in length. Each piece has 2 or 3 buds and are planted in pots. Pottery soil should be rich in humus, and apply long-term basal fertilizer, cover the thickness of the root to bury the rhizome, and maintain the water depth of 2 ~ 3cm. When 2 to 4 leaves are produced, water is added gradually as the petioles extend. Then put the pot into the pool, and finally the water depth can be controlled at 20 ~ 30cm, and make full visibility. Move the pots into the cold room before frosting. Keep the pots moist and do not freeze. Warm winters can be spent in the pool.

It is mainly used to understand the balance of immune function in patients with malignant tumor, virus infection, autoimmune disease, etc.

flow cytometry USES flow focusing technology to focus the cells in the center of the fluid and is irradiated by laser. By detecting the scattered light of the cells and the intensity of fluorescence generated by the specific combination of dye, the cell size, intracellular particle content and extracellular proteins are analyze
