Prolonging the shelf life of seed tubers under normal conditions helps the farmers to store their own produce as seed for the subsequent seasons, which in turn reduces the cost of production. Though, many chemicals such as methyl ester of naphthalene acetic acid. maleic hydrazide (MH) and CIPC can be used as sprout suppressants, which kill the sprouts, but as such they are not suitable for use in seed potatoes. Storag behaviour of seed tubers with treatments of chemicals like maleic hydrazide, zeatin, salicylic acid, chlorocholine chloride (CCC), tri-iodQ benzoic acid (TffiA) was studied on standing crop and resultant tubers were stored under normal open rack storage condition. CCC followed by MH performed well in controlling the sprout length. The histological studies of transverse section of tuber skin showed differences in thickness of ph ell em and arrangement of starch granules between control, MH and CCC treatments.
