Growth and yield of Oct.-sown Capsicum annuum, cv. Delphin, were investigated in a greenhouse under 12 day/night temperature regimes (16/15 degrees , 16/21 degrees , 20/12 degrees , 20/15 degrees , 20/18 degrees , 20/21 degrees , 24/12 degrees , 24/15 degrees , 24/18 degrees , 24/21 degrees , 28/15 degrees and 28/21 degrees C) applied during the early post-planting period (early Dec. to mid-Apr.). Fresh weight and leaf number were significantly correlated with 24-h mean temperature, but no significant effect of the day/night temperature amplitude was found. Plant height, leaf area and the leaf-area:length ratio were significantly correlated with 24-h mean temperature and with day/night temperature amplitude. The optimum 24-h mean temperature for vegetative growth was between 21 and 23 degrees . Yields of total and class 1 fruits (kg/msuperscript 2) and numbers of class 1 fruits were greatest at a 24-h mean temperature of 21-21.5 degrees . Raising the 24-h mean air temperature within the range 16.3 to 23.8 degrees significantly reduced the mean fruit weight of class 1 fruits. The day/night temperature amplitude had a significant positive effect on these variables. The effect of the day/night temperature amplitude on vegetative growth and on yield was of minor importance compared with the effect of the 24-h mean temperature.

“…The next stage began when the analogue control was replaced by the process computer. In 1974 a process computer was installed at our Research Station in a glasshouse consisting of 24 compartments and designed especially for glasshouse climate research (van de Vooren & Koppe, 1975). Soon af terwards, in 1975, the first computer was introduced into commercial practice.…”

“…An experiment was set up to investigate the effects of lower and of varying night temperatures relative to the usual ones in the Netherlands (van de Vooren et al, 1978). This experiment was carried out in the climate glasshouse of the Glasshouse Crops Research and Experiment Station at Naaldwijk (van de Vooren & Koppe, 1975).…”

Cucumber seedlings, cv. Farbio, planted in the greenhouse on 13 or 27 December or 10 or 24 January, were grown at 21-27 deg C day temperature and 12, 16 or 20 deg night temperatures until 1 April. Later planting produced more fruit than early planting. Night temperature had only a slight effect on fruit numbers/stem, but there was an optimum near 16 deg . The rate of fruit production between 12 and 20 deg was similar, but increased slightly with later planting. Production started earlier with higher night temperature and later planting. Fruit growth was not affected markedly by night temperature and fruit weight at harvest increased with season but was not dependent on the treatments. Fruit length was also independent of night temperature or planting date. (Abstract retrieved from CAB Abstracts by CABI’s permission)
