EFFECT OF DAY AND NIGHT TEMPERATURES ON EARLINESS AND FRUITPRODUCTION IN CUCUMBER |
| Author: | J. van de Vooren |
| Abstract:
The influence of day and nighttemperature, during the periode from planting till start of production, on earliness and the aftereffect on production of a greenhouse winter cucumber crop was studied in the climate glasshouse at Naaldwijk. Increasing nighttemperatures from 12–20°C did decrease earliness; a further increase till 24°C did not influence earliness. Only a slight effect on production and yield was found. Increasing daytemperatures from 20–26°C did decrease earliness. A daytemperature of 17°C disturbed plant development completely. A positive effect on yield and production was found from increasing day-temperature, probably caused by a better shoot development. | |
