| Abstract: | Five sorghum lines and one hybrid were used to study the changing law of sugar contents
and activities of sucrose synthase (SS) and sucrose phosphate synthase (SPS), the
correlation between soluble sugar contents and activities of SS and SPS on different
phases. The results showed that there are mainly negative correlation between soluble
sugar content and SS enzyme activities in the later growing stage, and mostly positive
correlation between soluble sugar content and SPS enzyme activities. The soluble sugar
content in stems was rising during the whole growing period. It reached the maximum when
sorghum was fully matured. Full-ripe stage is the best phase for harvest. |
