claimLight intensity affects root development in plants grown in a D-root growth system, as investigated by Miotto et al. in a 2021 study.
referenceUnder certain moisture conditions, the biomass of plant branches, leaves, and roots decreases as light intensity decreases, according to Zhou et al. (2022).
claimDecreasing light intensity causes the structure of chloroplasts and mitochondria to degrade or be destroyed, which negatively affects the metabolism of material and energy in plants.
claimJin et al. investigated the photosynthetic acclimation of larch to the coupled effects of light intensity and water deficit in 2024.
claimPlants adapt to different lighting environments, including photoperiod, light quality, and light intensity, to promote growth according to Zhang et al. (2023) and Shibaeva et al. (2024).
claimLight intensity affects celery growth and flavonoid synthesis, as reported by Qin et al. in a 2024 study.
referenceSoil moisture content and light intensity affect the growth and leaf physiological characteristics of squash plants.
claimGao et al. (2019) identified specific shading conditions that are more favorable for the growth of Aralia elata by studying the influence of light intensity on plant photosynthesis.
claimLight intensity, photoperiod, and light quality are regulatory factors that influence plant growth, development, and sugar metabolism, including effects on cell wall composition, starch granules, sucrose synthesis, and vascular bundle formation.
measurementViola yedoensis maintains normal chloroplast and mitochondrial structure under light intensities of 6000-8500 lx, allowing the plant to obtain sufficient energy for growth and metabolism (Yang et al., 2020).
claimLight intensity is a variable factor that controls plant germination, leaf proliferation and expansion, stomatal development, photosynthesis, and cell division, according to Bialevich et al. (2022), Bueno and Vendrame (2024), and Xu et al. (2024a).
claimThe rate of photosynthesis in plants accelerates as light intensity increases up to a specific light saturation point, after which photosynthesis is no longer affected by further increases in light intensity.
claimZhao et al. (2024a) identified a potential mechanism where miRNA mediates the response to light intensity in the energy metabolism of Isatis indigotica.
referenceXu et al. (2024a) studied the effects of light intensity on the photosynthetic characteristics of Hosta genotypes that differ in the glaucousness of their leaf surfaces.
claimHuang et al. reported in 2024 that high phosphorus availability and low light intensity reduce the competitive ability of the invasive plant Chromolaena odorata in tropical coral islands.
referenceLiu et al. (2022) studied the effects of varying light intensity on the morphological structure and physiological characteristics of Gleditsia sinensis seedlings.
referenceLiu and Van Iersel (2021) reviewed the photosynthetic physiology of blue, green, and red light, specifically examining light intensity effects and the underlying mechanisms.
claimLight intensity affects ectoplasm and cell division, light quality affects the proliferation of healing and cultured tissues as well as organ differentiation, and photoperiod affects the differentiation of organ tissues.
claimZhu et al. (2024) performed an integrated multi-omic analysis revealing that suitable light intensity regulates polysaccharide biosynthesis in Bletilla striata leaves through carbon metabolism.
claimMedicago sativa is a light-demanding species whose reproductive growth is extremely dependent on light intensity.
claimYang P. et al. (2020) investigated the effects of light intensity on the material and energy metabolism of Viola yedoensis.
claimDeeper light penetration into the canopy improves crop photosynthesis at high light intensities (summer) but not at low light intensities (winter).
claimIn celery, increased light intensity leads to an increase in plant height and aboveground biomass, as well as affecting nutritional quality and the accumulation of flavonoid components.
measurementThe polysaccharide content in Changium smyrnioides increased from 6.53% to 10.80% when relative light intensity was reduced from 100% to 44.84%, and subsequently decreased to 8.79% when relative light intensity was further reduced to 10.56%.
claimLight intensity directly affects the opening and closing of stomata on plant leaves, thereby regulating plant water consumption through transpiration.
