Abstract
Vertical farming using light-emitting diode offers potential for the early production phase (few weeks) of young ornamental plants. However, once transferred to the greenhouse, the photosynthetic acclimation of these young plants might depend on this initial light regime. To obtain insight about this acclimatization, Chrysanthemum (sun species) and Spathiphyllum (shade species) were preconditioned in growth chambers for 4 weeks under four light qualities: blue (B), red (R), red/blue (RB, 60% R) and white (W) at 100 mu mol m(-2) s(-1). Monochromatic light (R and B) limited leaf development of both species, which resulted in a lower leaf mass per area when compared to multispectral light (RB for Chrysanthemum, RB and W for Spathiphyllum). R-developed leaves had a lower photosynthetic efficiency in both species. After the light quality pretreatment, plants were transferred to the greenhouse with high-intensity natural light conditions. On the first day of transfer, R and B preconditioned leaves of both species had an inhibited photosynthesis. After 1 week in natural light condition, rapid light curve parameters of Chrysanthemum leaves that developed under B acclimated to sunlight had a similar level than RB-developed leaves unlike R-leaves. Spathiphyllum leaves showed a decrease in maximum electron transport rate and this was most pronounced for the R pretreatment. After 1 month, R-preconditioned Chrysanthemum had the lowest dry mass, while no effects on the dry weight of Spathiphyllum with respect to the pretreatments were observed. Light quality during preconditioning affected the leaf ability to acclimate to natural high light intensities in greenhouse environment.
