The first objective of this study is to determine the time when the main stem of Luffa cylindrica is normally most elongated. In all the six plants observed the main stems were elongated more in the daytime than at night. The largest difference of the stem between daytime and night was obtained of 27th July, 1992. At that time, the stem was elongated by 8.0cm in the daytime as against 5.4cm at night.
The second objective of the present study is to survey the assumption in people of different ages of the elongation of L. cylindrica. The majority of the primary school pupils assumed that it would be elongated more in the daytime than at night based on what they have learned in their school science lessons. On the other hand, the majority of the university students and science teachers thought that it would be elongated more during night time based on informations that they have obtained from various sources.
