There are two mechanisms by which light affects plant growth, development and yield and quality: one is to affect the photomorphogenesis of plants through photoreceptors; the other is to regulate plant photosynthesis through photosynthetic pigments, changing carbon and ammonia metabolism and photosynthetic products in plants. allocation. In addition to light intensity and photoperiod, light quality …

Effect of LED Grow Light Quality on Nitrate Content（二）
Urbonaviciute et al. (2007) studied the effects of 92% LED red light (640nm) + 8% near-ultraviolet light, 86% LED red light + 14% LED blue light, 90% LED red light + 10% cyan light on lettuce with fluorescent lamps as a control. Growth and effects of nitrate content. The sugar content of 86% LED red …

Effect of LED Grow Light Quality on Nitrate Content（一）
The accumulation of nitrate in vegetables is a complex process, which is controlled by nitrate nitrogen absorption, reduction and assimilation, and is affected by light conditions. The main way of nitrogen assimilation in plants is that the ammonia generated by the reduction of nitrate nitrogen directly participates in the synthesis and transformation of amino acids, …

Typical state of plant photosynthesis（四）
avoidance reaction The mechanism of how crops respond to changes in light signals in the surrounding environment has always been one of the hotspots of international botany research. The plant shade avoidance response refers to the interaction of various forms of light signal receptors in cells, which causes stem elongation after sensing that the plant …

Typical state of plant photosynthesis（三）
Continuous lighting Continuous illumination refers to a photoperiod management method that uses artificial light sources under the condition that the illumination intensity and light quality are determined, and the illumination time exceeds 24 hours. Continuous light can increase the growth of Arabidopsis, lettuce, several types of potatoes, rosettes (Velez-Ramirez et al., 2011). However, continuous light …

Typical state of plant photosynthesis（二）
photoinhibition Photoinhibition occurs when light energy exceeds the demand for photosynthesis. The basic feature of photoinhibition is the reduction of photosynthetic efficiency (quantum efficiency of photosynthetic carbon assimilation and photochemical efficiency of photosystem II). According to the difference in the recovery speed of photosynthetic efficiency after the removal of photoinhibitory conditions, it can be divided …
