Outline of Final Research Achievements

In sweet sorghum, in order to develop the cultivation technique for increment of stem yield and reduction of lodging damage, the relation between the pattern of internode characteristics and growth, stem yield was investigated. As a result, it was clear that the internode length pattern was the effective measure for analysis of stem growth process and the internode diameter pattern was correlated closely with the stem yield. Based on the analysis results using these patterns, it was suggested that the additional fertilizer in early growth stage should increase the diameter of basal internodes, resulting in the enhancement of the productivity and the lodging resistance of stem.
