Light has a regulating effect on plant growth, especially on the differentiation of young plants. Usually, during plant maturation, the more seeds a plant produces after photosynthesis, the more seeds it produces. In addition, light promotes the growth of roots, stems and leaves and prevents the plant from growing.
In addition to its metabolic effects on plant growth, light can also have a direct effect on plant organ differentiation and morphology by inhibiting cell growth and promoting cell differentiation. The direct effect of light on plant morphogenesis is called light paradigm effect. Light is a necessary condition for the normal growth of green plants, and the light factors affecting plant growth are mainly light intensity, light wavelength and light duration. The duration of light is closely related to the photoperiodic phenomenon of plants. The phenomenon that plants control flowering by sensing changes in diurnal length is called photoperiodic phenomenon, that is, the phenomenon that plants control physiological responses by sensing diurnal length. In addition to inducing flowering, light also affects the elongation of flowering stems, the formation of tubers and tubers, the dormancy of buds and the shedding of leaves.
In general, light is a promoter of plant growth. For most of the perennial plants, it promotes growth under long daylight conditions and induces dormancy under short daylight conditions (orchid micro appreciation: on the premise that orchids need to be supplemented by light, when using plant supplementation lights to supplement orchids, it is necessary to adjust the supplementation light on time, off time and total daily supplementation light duration by taking into account the changing pattern of natural light duration during the change of spring, summer, autumn and winter seasons). Therefore, light is very important in the life of plants, and it is important to improve photosynthetic yield and use light regulation factors to improve agricultural production. Therefore, the choice ofusing illumination sensors to monitor the illumination level is more conducive to promoting plant growth.
