An experimental study was conducted to define the response of aubergine to different temperatures in controlled greenhouses. Set temperatures of the greenhouses were 14, 18, 22, 26 and 30˚C. In terms of vegetative growth, the plant response was the highest to the highest temperature then gradually decreasing for the lower temperatures. | Tr.

Received: .1995 Abstract: An experimental study was conducted to define the response of aubergine to different temperatures in controlled greenhouses. Set temperatures of the greenhouses were 14, 18, 22, 26 and 30˚C. In terms of vegetative growth, the plant response was the highest to the highest temperature then gradually decreasing for the lower temperatures. This was in contrast with the fruit development since as the temperature decreased from 30˚C, mean fruit weight and size increased, and the total fruit yield was highest in 22˚C which indicated an optimum temperature. However, there was no optimum for vegetative growth. This was found, by using a growth model, about 32 to 34˚C for almost all plant components. The results are useful for production planning. Sıcaklığın ve Hasat Zamanının Patlıcanın (Solanum melongena L.) Büyümesi ve Meyve Verimi Üzerine Etkisi Özet: Bu çalışmada, Patlıcanın sıcaklığa olan tepkisi, sıcaklığı kontrol edilen 4 adet serada belirlenmiştir. Seraların kurulan sıcaklıkları 14, 18, 22 ve 30˚C idi. Ölçülen verilerden, sıcaklık arttıkça bitki büyümesinin arttığı görülmüştür. Ancak, bunun tersi olarak, sıcaklık arttıkça ortalama meyve boyutları ve ağırlığı dolayısı ile toplam meyve verimi azalmıştır. Meyve verimi açısından en uygun sıckalığın 22˚C olduğu görülmüştür. Bununla birlikte, ölçümlerden bitki büyümesi açısından herhangi bir en uygun sıcaklığa rastlanmamasına rağmen, bir bitki büyüme modelini kullanarak bunun yaklaşık 32 ile 34˚C arasında olduğu bulunmuştur. Sonuçlar üretim planlaması açısından .
