Abstract

Effect of staling on cane quality and bud germination using whole cane and seed-cane pieces was investigated using sugarcane variety CoSe 92423. Inordinate delay in harvesting to planting of seed-cane pieces show reduce germination. This decrease in sprouting is more in seed pieces as compared to the whole stalk subjected to staling. The bud moisture is critical, this should not be less than 65 per cent. Buds from stale cane recorded low moisture and relatively higher accumulation of endogenous IAA and phenols; recorded steep decline in acid invertase activity on prolonged staling. Pre-planting soaking of seed cane pieces in water containing ethrel (200 mg/L) for 12 h improved sprouting of stale cane.
