- •
Dynamics of sucrose accumulation is balanced by activities of sucrose synthesising and hydrolysing enzymes in the sink.
- •
Significantly higher soluble acid invertase and neutral invertase activities in leaves of radiation induced mutants of sugarcane.
- •
Lower activities of invertases in the culm favoured higher sucrose accumulation in the culms of the mutant AKTS-02.
- •
Soluble acid invertase proven to play a crucial in regulation of sucrose accumulation in the internodes.
