Air Circulation

Air circulation, generally an integral part of environmentally-controlled plant growth chambers, retarded tomato (Lycopersicon lycopersicum Karstens) seedling growth seismomorphogenetically. Continuous air movement at a speed of 0.5 to 0.7 m·s-1 inhibited growth by about 40%. Growth inhibition was noticeable with as little as 15 min of daily exposure to the air circulation; a continuous exposure gave the greatest amount of growth inhibition. The retarding effect of air on seedling growth was transient and required a continued daily exposure to air movement. Continuous aeration of seedlings inhibited growth to such an extent that in a two factor experiment, ie aeration and water stress, the water stress effects were completely masked in the aerated chamber by the aeration effect. The results have important implications for plant growth experiments in chambers equipped with air circulation: seedling growth may be affected more by the air circulation in the growth chamber than by an experimental treatment.

Environment Chamber

Light-emitting diode (LED) lamps signify one of the most important advances in artificial lighting for horticulture over the last few decades. The objective of this study was to compare the cultivation of four horticultural plants using a conventional white LED tube (T0) light against one with a good spectral fit to the maximum photosynthetic response (T1) at two intensities. The experiment was carried out with two types of young lettuce, tomato, and bell pepper plants. In a controlled environment chamber, six and four lamps per square meter were used to achieve high (H) and low (L) intensity, respectively. We measured the lighting parameters illuminance (lux) and photosynthetic photon flux (PPF) intensity (µmol·m−2·s−1). The dry and fresh weight, leaf area (LA), and specific index were measured to gauge plant growth. The photosynthetic activity and energy efficiency (EE) were recorded for each species over 60 days of cultivation. The results clearly demonstrate that, compared with conventional LED lamps, the specific horticultural LED lamps with an improved light spectrum increased the EE of the evaluated vegetables by 26%. At both the studied light intensities, plant growth was clearly more closely linked to the spectral fit of the light to the maximum photosynthetic response recorded by McCree (1972) than to PPF or illuminance (lux). We therefore suggest that a specific, detailed spectral distribution study be conducted to predict the effect of the specific quantity and quality of light used in this study on a single parameter of plant growth.
