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.

Heat Tolerant

Three broccoli (Brassica oleracea L. Italica group) cultivars (Baccus, Packman, and Southern Comet) were grown for 14, 24, or 34 days at 22/18C (day/night) in a greenhouse. Then plants were moved to growth chambers where temperatures were maintained at 26/22, 30/26, or 34/30C and were grown for 1, 2, or 3 weeks before returning them to the greenhouse. A1 varieties when exposed to high temperatures developed smaller heads Packman when exposed to high temperatures resulted in a reduction in uniformity. Other cultivars were not effected. Lack of openness, an important marketable characteristic was reduced by high temperatures. However, Baccus at 34 days old was not effected by the heat. We would expect this response since this is the head development stage and cultivar is heat tolerant. Plant exposed to high temperatures developed heads earlier when held for 3 weeks. When plants were held at 36/30C for 3 weeks, the largest reduction in plant growth was recorded. However, all plants showed a reduction in growth when exposed to high temperatures.
