Abstract

Some soybean cultivars exhibit a bimodal temperature response. Their hypocotyls elongate normally at 20 and 30 C but are inhibited at 25 C. The inhibition is inducible. It manifests itself, or continues to be manifest, after seedlings are transferred to 20 or 30 C. Sensitivity to 25 C is limited to early seedling development and disappears about 6 days after seeds are supplied with water.
