‘‘Our collaboration and trials with tomato seedlings identify specific light wavelengths and light intensities for growers and their operations teams to produce more uniform stock material with easier matching of rootstock and scions for grafting and successful healing.’’
The project focus and goal identified the light spectra and intensities that were most cost-effective to produce consistent shoots and seedling heights for tomatoes.
The grower was looking to ensure successful transport and transplant of the seedlings to greenhouse production environments across North America. Strong root development was also critical for greenhouse transplant success.
Initial trials of blue and red light treatments were conducted with ELIXIA adjustable spectrum LED lights to determine most effective spectra and intensity with six days of healing treatment after grafting.
SIERA light bars were used for indoor, vertical systems in full production.
Red light treatment resulted in healthy seedlings and shoots, good colour and good root development overall.
Six days healing treatment in indoor environment achieved 95.5% average success rate for tomato shoots, rooting and plant height before transport and greenhouse transplant.
