| Abstract:
Tomato (Lycopersicon esculentum Mill.) cv. Carmello F1, cucumber, (Cucumis sativa L.) cv. Mustang F1 and sweet pepper (Capsicum annuum L.) cv. Gedeon F1 seedlings were subjected to negative or positive differences in day and night temperatures (DIF). Growth behaviour, i.e. plant height, internode length and number, leaf number, leaf area and stem diameter were studied in each case. Cucumber plant height was reduced in the minus DIF treatment. Whereas, as cucumber the response of tomato or sweet pepper was not as clear as cucumber under the experimental conditions. | |
