With a view to study the effect of trimming of propagules on the rate of shoot multiplication
during micropropagation of sugarcane, the shoot cultures were subcultured on fresh multiplication
medium after trimming the leaves of shoot clumps to different lengths i.e. 3.0, 4.0, 5.0 and >6.0
cms. The results showed that trimming of propagules to a height of 3.0 cm during subculture
enhanced the rate of shoot multiplication as well as shoot growth in variety CoSe 01235 suggesting
that this practice could be helpful in producing more number of plantlets in a seed multiplication
programme through in vitro micropropagation.
