Microwaves are a type of electromagnetic wave, with frequencies ranging from 300MHz to 300GHz, corresponding to wavelengths between 100cm and 1mm, placing them between infrared and radio waves. Within the microwave spectrum, the band from 1 to 25cm is specifically allocated for radar, while the rest is used for telecommunications. To prevent interference from civilian microwave power with radio communications, broadcasting, television, and radar, international regulations set the frequency for industrial, scientific research, medical, and household civilian microwaves at ±50MHz around 2450MHz. Consequently, the frequencies used by microwave digestion instruments are primarily 2450MHz, as are those in household microwave ovens.
Lighting conditions are also an important factor during cultivation, particularly concerning light intensity, quality, and duration: 01 Light Intensity - The intensity of light significantly impacts the proliferation of cultured cells and the differentiation of organs. Current research indicates that light intensity has a notable effect on the initial division of explants and cells. Generally, higher light intensity results in robust seedling growth, whereas weaker light intensity can lead to excessive elongation. Under dark conditions, plants exhibit: slender stems, long internodes, fragility (underdeveloped mechanical tissue), small and curled leaves, poor root development, overall yellowing of the plant, a phenomenon known as chlorosis.
