Effects of high temperature on nitrogen fixation in soybean cultivars
Chapter
Abstract
The adverse effects of root temperatures on nitrogen fixation have been shown for numerous legumes (Gibson, 1977, Sprent and Minchin, 1984). Biological nitrogen fixation is often affected more by temperature than is the general growth and photosynthesis of the plant (Granhall, 1981). Steward (1966) has also suggested that nitrogen fixation is often especially inhibited by temperature extremes which have less effect on plant growth. Here the effect of temperature stresses on the ARA of two soybean varieties is discussed.
