Effect of light intensity during growth of greenhouse tomatoes on photosynthetic rate






Acta Horticulturae (58): 221-225

Effect of light intensity during growth of greenhouse tomatoes on photosynthetic rate

Tomato seedlings (several cvs) were grown for 21 days under natural light (average intensity 15.5 klux) for a 15 h daylength, with a 24 deg /18 deg C day/night temperature regime; subsequently some were grown for 70 days in simulated winter conditions, with light intensities of 3 or 6 klux for a 9-h daylength, and a 20 deg /18 deg day/night temperature regime. They were then exposed to light intensities of 2-17 klux, and their photosynthetic activity was measured.
