Effect of postharvest application of plant growth regulators on sprouting behaviour of sweet potato.

Tuberous roots of sweet potato cv. Tripti harvested at maturity 5 months after planting were treated by dipping for 5 min in 1000, 2000 or 3000 p.p.m. NAA, Cycocel [chlormequat], Ethrel [ethephon] or maleic hydrazide. Treatments with NAA at all concentrations either delayed or inhibited sprouting and reduced cumulative weight loss during storage. NAA reduced sprouting by 40-73% after 2 months of storage at ambient temperature in Bangladesh; the effect was more pronounced at higher concentration. On the other hand, Ethrel enhanced both sprouting and rotting. Maleic hydrazide slightly delayed sprouting, but more sprouts were produced. Cycocel had no significant effect. Treatment of tubers with NAA after desprouting completely inhibited further sprouting. Treatment of tubers 15 d after harvest had a lesser effect on inhibition of sprouting.
