A novel multilayer cultivation strategy improves light utilization and fruit quality in plant factories for tomato production
Published 2025-07-01Subjects: Get full textPlant factories using artificial lighting are a promising solution to food security and urban agricultural challenges. However, cultivation of fruit-bearing crops such as tomatoes remains limited due to their high light demands, long growth periods, and tall plant structure. In this study, we aimed...

Effect of leaf removal on photosynthetically active radiation distribution in maize canopy and stalk strength
Published 2017-01-01Subjects: Get full textThe objectives of this study were to determine how the distribution of photosynthetically active radiation (PAR) in a maize canopy affected basal internode strength and stalk lodging. The distributions of PAR within the canopies of two maize cultivars (Zhongdan 909 and Xinyu 41) were altered by remo...

Flumetralin and dimethyl piperidinium chloride alter light distribution in cotton canopies by optimizing the spatial configuration of leaves and bolls
Published 2020-07-01Subjects: Get full textPlant growth regulators (PGRs) are frequently used to adjust cotton growth and development. The objectives of this study were to determine how PGRs affect plant morphology, light distribution and the spatial distribution of leaves and bolls within the cotton canopy. The field experiments were carrie...

Dose-response of tomato fruit yield to far-red fraction in supplementary lighting
Published 2025-07-01Subjects: Get full textSupplementary LED lighting in greenhouse horticulture is typically rich in red light (R; 600–700 nm), while it lacks far-red light (FR; 700–800 nm), resulting in growing conditions with lower-than-solar far-red fractions [<0.46; FR/(R + FR)]. In these light environments, the addition of FR ca...
