Effects of Extended Light/Dark Cycles on Solanaceae Plants.

The absence of an externally-imposed 24 h light/dark cycle in closed plant production systems allows setting the light environmental parameters in unconventional ways. Innovative lighting modes for energy-saving, high-quality, and yield production are widely discussed. This study aimed to evaluate the effects of the light/dark cycles of 16/8 h (control) and 24/12 h, 48/24 h, 96/48 h, 120/60 h (unconventional cycles) based on the same total light amount, and continuous lighting (360/0 h) on plant performance of some Solanaceae species.

Continuous LED Lighting Enhances Yield and Nutritional Value of Four Genotypes of Brassicaceae Microgreens.

The effect of continuous lighting (CL, 24 h) and light spectrum on growth and nutritional quality of arugula (), broccoli ( var. ), mizuna var. ), and radish ( var.

[The effect of daily exposure to low hardening temperature on plant vital activity].

Phenomenological responses of plants to daily short-term exposure to low hardening temperature was studied under chamber and field conditions. Experiments were carried out on cucumber (Cucumis sativus L.), barley (Hordeum vulgare L.

[The effect of short-term daily temperature drops on the processes of organogenesis in Cucumis sativus L. under conditions of different photoperiods].

The effect of nightly temperature drops of different durations (2, 4, and 6 h) on the processes of apical and axillary meristem organogenesis was studied in young Cucumis sativus L. under short photoperiod (day/night, 10/14 h), long photoperiod (16/8 h), and continuous light. Nightly temperature drops for 2 h had no effect on cucumber development under all studied photoperiods; however, longer temperature drops (4-8 h) accelerated the development under long photoperiod and continuous light.
