LED for Healing of Grafted Tomato Transplants

LED for Healing of Grafted Tomato Transplants

October 25, 2016

Grafted tomato seedling propagation must be optimized to increase production efficiencies. Grafting has several steps that include growing, grafting, healing, and acclimation. Healing is considered the most critical step. Healing is the joining of cambium between rootstock and scion to form vascular tissue and is commonly done under modified greenhouse conditions or inside healing chambers.

Effects of Spectral Ratios on Miniature Rose Growth and Morphology

Effects of Spectral Ratios on Miniature Rose Growth and Morphology

October 25, 2016

Winter months in California have a Daily Light Integral (DLI) of 10-20, which is inadequate for optimal plant growth. To address this challenge, Light Emitting Diode (LED) lamps are beginning to be used in preference over High Intensity Discharge (HID) lamps for their higher energy efficiency and longevity.

Achieving Better Tasting Basil Grown with LumiGrow LEDs

Achieving Better Tasting Basil Grown with LumiGrow LEDs

October 13, 2013

This LumiGrow study uses LED fixtures to examine the effects of varying light ratios on basil plants in a sole-source environment. By exploring different ratios of blue, white and red light on basil growth, we enable growers to use programmable LED light spectrums to steer plant growth and flavor.

Analysis of Arabidopsis Light-Sensitive Mutants Grown Under Different Ratios of LED or Fluorescent Lighting

Analysis of Arabidopsis Light-Sensitive Mutants Grown Under Different Ratios of LED or Fluorescent Lighting

October 13, 2015

Our analysis of leaf size, shape, and number, as well as days to flowering, indicated differences in growth patterns between light conditions. Mid PPFD and max PPFD LEDs also showed some phenotypic growth differences compared to fluorescent lighting.

LED Lighting and Phalaenopsis Orchids, Light Wavelength Effect on Flowering Spike

LED Lighting and Phalaenopsis Orchids, Light Wavelength Effect on Flowering Spike

October 13, 2015

LED lighting allows for specific application of light wavelength and intensity. Different plant morphologies are achievable by manipulating light at specific wavelengths in a way that previous lighting technologies did not allow. Selecting various wavelengths of light can influence the growth and morphology of horticultural crops including the currently popular Phalaenopsis orchid. The object of the work is to influence the growth and elongation of Phalaenopsis orchid flower spikes under varying intensities of red and blue light.
