Description
Summary:It is very important to keep the effective canopy structure in soybean from flowering to seed developing period. The petiole elongation effects the position of leaf blade in canopy. In order to clarify the varietal differences in the petiole elongation characteristics in soybean, the eleven determinate growth type soybean cultivars were used. The first trifoliolate leaf on the main stem was the shortest and longer at upper position, while uppermost 2nd-4th petiole was the longest among all the petioles. The number of leaves on the main stem and the position of the longest petiole varied among cultivars with different seed size and stem length, but there was no difference in the pattern of petiole length. The pattern of petiole length and that of internode length on the main stem appear to be similar. So, the relationship between the Nth petiole length and the (N-1)th internode length belong to the same phytomer were investigated. Each cultivar showed significantly positive correlation between the Nth petiole length and the (N-1)th internode length. This result indicated that the elongation pattern of petiole is similar to that of internode irrespective of cultivar. By investigating the response of petioles to physical and chemical treatments based on the information of internode, the positioning of leaf blade could be controlled more efficiently. It would be possible to modify plant type of soybean with these informations.
