Research and Other Documents Relevant to Grow Lighting and Horticulture.

plant-lightingTo better understand the needs of plants, it is helpful to visit scientific research documents, and other useful bits of knowledge.

Pursuit of knowledge can lead to new techniques and products.

Products properly informed by Scientific principals will display superior performance.

Techniques can be employed to aid horicultural productivity, improve the smell, taste, color of foods and ornamental crops, increase yields, overall health, quality and shelf life.

Combining different light sources in hybrid combinations, triggering responses with discrete spectrum, are being born out as a suitable approach to optimizing results while saving energy and maintenance.

Implementation can be useful in the Greenhouse, Outdoors and in the Greenhouse. 

Switching: The Flower Inititator can be used with or as an alternative to curtains.
  • Photoperiodism: Many angiosperms flower at about the same time every year. This occurs even though they may have started growing at different times. Their flowering is a response to the changing length of day and night as the season progresses. The phenomenon is called photoperiodism. It helps promote cross pollination
  • Regulation of flowering time by light quality. Pablo D. Cerda´n & Joanne Chory. Changes in light quality serves as a warning of competition, triggering a series of changes.
  • THE REGULATION OF FLOWERING IN LONG-DAY PLANTS. Author: D. Vince. ISHS Acta Horticulturae 14: Symposium on Flower Regulation in Florist Crops. The purpose of this paper; discuss the mechanism through which long-day conditions are perceived by the leaves, consider any differences between the lighting treatments needed to accelerate flowering in long-day plants, or the achieve other long-day responses, and those needed to inhibit flowering in short-day plants.
  • Light Signals and Flowering. Brian Thomas*Warwick HRI, University of Warwick, Wellesbourne CV35 9EF, UK. Physiological studies over a long period have shown that light acts to regulate flowering through the three main variables of quality, quantity, and duration.
  • Photoreceptors and Regulation of Flowering Time. Chentao Lin *Copyright © 2000 American Society of Plant Physiologists. One of the most important environmental factors affecting flowering time is the daily duration of light, the photoperiod.
