説明

Effects of different temperatures and water regimes on soil and leaf water potential, photosynthesis, growth and dry matter production of mungbean during pod formation were examined in the phytotron growth chambers of the Kyushu University, Japan. Temperatures were 15, 20, 25 and 30℃ and water regimes were well irrigation and light irrigation. Almost all parameters (except root dry weight) of mungbean were much reduced in the light irrigated pots than those in the well irrigated pots irrespective of temperature gradients except 15℃. Effects of different temperature gradients were more pronounced in photosynthesis, plant height, number of pods per plant, total dry matter and dry matter accumulation in pods in the well irrigated pots; and soil water potential, leaf water potential, leaf area per plant and root dry matter in the light irrigated pots. In the well irrigated condition, 25℃ was found to be the most favorable for growth and development of mungbean, but in the light irrigated condition no definite temperature was found to be most favorable in all cases. It may be suggested that for getting higher photosynthesis, growth and dry matter production in mungbean an adequate soil moisture accompanied with 25℃ is the best environment for the plant.
