Intensity Of Response

The role of different temperature regimes (low, 18 °C day: 15 °C night (LTR); intermediate, 23 °C day: 18 °C night (ITR); and high, 28 °C day: 23 °C night (HTR)) in the development of tomato (Lycopersicon esculentum Mill.) flowers was studied. In general, flowers produced in LTR contained significantly greater numbers of petals, stamens, carpels, and locules than did plants grown in HTR. In ITR, the number of these organs was intermediate to plants grown in LTR and HTR, but was not significantly different from them in all cases. Gibberellic acid (GA3) also induced an increase in the number of petals, stamens, carpels, and locules; however, its effect was much greater on plants grown in ITR and HTR than on LTR, implying that LTR may produce at least part of its effect through increased levels of endogenous gibberellins. The intensity of response to different temperature regimes was variable for each of the three cultivars studied.

Large Yield

Vermiculite–perlite–clay (Putnam subsoil) mixtures with added nutrients were evaluated as growth media for periods up to 112 days in 3.8-liter jars using tomato (Lycopersicon esculentum Mill. cv. Patio Hybrid) as a test plant. Although vermiculite–perlite (V–P) ratio had no effect, subsoil levels above 50 g/jar and low N rate (22.5 meq/50 g subsoil) gave greatest growth of 42-day transplants. For long-term periods (112 days), only fruit yield was affected by V–P ratio, a 1:1 (vol/vol) proportion giving the highest yield. Large yield increases were obtained by increasing subsoil to the 150-g or 300-g levels. Fresh and dry plant weights increased with each increment of subsoil, and high N rate (45 meq/50 g subsoil) increased both vegetative growth and fruit yield to levels approaching those obtained with Cornell peat-lite mix A. The V–P clay mixes held more than twice the available moisture present in the peat-lite mix.

Temperature Controlled

Tomato (Lycopersicon esculentum Mill.) plants grown under low (LTR), intermediate (ITR), and high (HTR) temperature regimes produced fruits which were significantly different in certain characteristics. Under LTR, fruits were larger, both in fresh weight and size, and contained a greater number of locules than the fruits produced under ITR, which were larger than those developed under HTR. Fruits from plants maintained in temperature-controlled growth chambers before and after pollination were generally larger than those transferred to a greenhouse after pollination. Some abnormalities were observed in fruits grown under LTR but not in those produced under ITR and HTR.
