Abstract

|
|
To study the effect of global warming on the growth of plants and plant populations throughout their life cycle under a field-like condition, we constructed a Temperature Gradient Chamber (TGC) in Tsukuba, Japan. The chamber had slender shape: 30 m long, 3 m wide, and 2.5 m high. That satisfactory performance was confirmed by a test throughout all seasons in 1998: the projected global warming condition in the near future was simulated. That is, independent of a great daily or seasonal change in ambient meteorological conditions, air temperatures at the air outlet were warmed 5℃ higher than those at the ambient (the annual mean was 14.3℃) with precision of ±0.2℃ (the annual means were 19.2℃) with a rising rate of approximately 1℃ every 5 m. This chamber will enable us to study the effects of global warming on growth of plants and plant populatoins because their abilities to control air temperature are excellent. TGC is expected that it would be utilized for studying the effect of global warming on plant growth under natural weather conditions.
