Effects of Light Intensity and Photoperiod on Morphological Development and Photosynthetic Characteristics of Coriander

Abstract

Coriander (Coriandrum sativum L.) is prized for its aroma and medicinal properties and is extensively employed in various cuisines. Light intensity and photoperiod greatly impact its phenological development. The application of light-emitting diodes (LEDs) in facility cultivation systems enables precise control of lighting conditions, leading to enhanced energy efficiency in coriander cultivation. This study investigated three levels of light intensity (133, 200, and 400 μmol·m−2·s−1) and three photoperiods (8L/16D, 16L/8D, and 24L) to comprehensively assess their effects on coriander’s morphological development, photosynthetic characteristics, and energy utilization efficiency. The objective was to identify a combination conducive to efficient and energy-saving coriander cultivation in PFALs. Results indicated that high light intensity (400 μmol·m−2·s−1) with continuous lighting (24L) reduces coriander’s photosynthetic capacity, while 24-h of continuous lighting can boost yield at the expense of energy efficiency. An 8-h photoperiod significantly decreases the yield compared to 16 h. Low light intensity inhibits plant development, indicating that 133 μmol·m−2·s−1 is suboptimal. For optimal efficiency and yield, a light intensity of 200 μmol·m−2·s−1 and a 16-h photoperiod are recommended in coriander PFAL cultivation. These findings advocate for the adoption of these specific conditions for the indoor cultivation of coriander within PFAL systems.

Do Climate Conditions Affect the Quality of the Apiaceae Fruits’ Essential Oils?

“…As can be seen, the linalool content varied from 65.3 to 80.5%, and it was noticed that higher temperature, precipitation, and insolation lead to higher levels of linalool. There are reports that climatic factors have an effect on the quantity of essential oil and dry matter yield of coriander [62], as well as development and morphological characteristics [63]. However, previous results showed that coriander has favorable growth conditions in Serbia [64].…”
