One of the main reasons why the light bulb turns red is the light. It is the most visible and effective way to make the light bulb turn red. Put it in a place where there is enough sunlight, its color begins to get darker, and then slowly turns red. In the autumn of each year, the atmospheric concentration in the air becomes lighter, the visibility in the air becomes stronger and stronger, the intensity of solar radiation will also increase, and the intensity of ultraviolet light in a year will reach the highest value, so autumn is the best time for the multi meat bulb to change color. The color depth of the red light bulb is closely related to the duration and intensity of the sunshine.
When the temperature drops in winter, the color of the bulb will deepen in the low temperature environment. At the beginning, part of the fleshy bulb turned red, and the color gradually deepened. At last, the whole leaf turned red. This phenomenon is caused by the self-protection function of the light bulb. The anthocyanin in the light bulb has the function of cold protection and warmth preservation. In winter, the relatively high temperature during the day can meet the slow growth of the fleshy bulb, not to hibernate. At night, the temperature drops rapidly. The cold environment can promote the synthesis of anthocyanins. The lower the temperature, the higher the anthocyanins are generated. When the anthocyanin in the body of the fleshy bulb increases, it will become more and more red.
To sum up, the fact that the multi meat bulb can change color is to change its own color with the help of natural force. Generally speaking, it's actually the change of the pigment in the body of the light bulb. It's because of the chemical reaction of different pigments in its body under different reasons, which changes the proportion of its own pigment, thus causing the phenomenon of color change. There are two main reasons for the change of pigment in the bulb: light and temperature. Meaty bulb is a lovely little plant, you may as well try to let it change color with my method
