Petunia hybrida Hort. “Easy Wave Pink”, a qualitative long-day plant (LDP), was investigated to study the effects of night interruption light (NIL) provided by light-emitting diodes (LEDs) quality shifting on morphogenesis, blooming, and transcription photoreceptor genes. Plants were grown in closed-type factory employing white (W) LEDs at an intensity 180 μmol·m−2·s−1 PPFD for short day (SD, 1...

AIMS To estimate the financial cost to the NHS of infant crying and sleeping problems in the first 12 weeks of age and to assess the cost effectiveness of behavioural and educational interventions aimed at reducing infant crying and sleeping problems relative to usual services. METHODS A cost burden analysis and cost effectiveness analysis were conducted using data from the Crying Or Sleeping...

Commercial producers of herbaceous ornamentals have reported that long-day plants sometimes flower under short-day conditions when the photosynthetic daily light integral (DLI) is high, but little research-based information available to support phenomenon. We grew seedlings tickseed (Coreopsis grandiflora), echinacea (Echinacea × hybrida), lavender (Lavandula angustifolia), lobelia (Lobelia spe...

This study examines how the day neutral plant (DNP) Pelargonium × hortorum L.H. Bailey ‘Ringo 2000 Violet’ is impacted by LED night-interruption light (NIL) quality shifting in terms of flowering, morphogenesis, and transcription photoreceptor genes. A closed-type factory with white (W) LEDs providing 180 ?mol·m?2·s?1 PPFD for long (LD, 16 h light, 8 dark), short (SD, 10 14 or SD 4 night interr...

_______________________________________________________________________________ Abstract Two genotypes of male broilers were given 12 h of daily illumination; as a conventional photoperiod, with the final hour at reduced illuminance to simulate dusk, or with 1 h of the light given during the middle of the night. The lighting modifications had no significant effect on any performance variable or...
