Studies on the cold storage life (45 to 48° F and 85 to 90 per cent relative humidity) of Langra mangoes at different stages of maturity after precooling and after 2 and 4 days exposure to room temperature have shown that hard green fruits of this cultivar can be successfully stored for 35 to 45 days depending upon their stage of maturity. Precooling helped in increasing the satisfactory storage life by way of supression of intensity of respiration and prolongation of the duration of respiratory climacteric. Fruits of advanced maturity remained in good condition only for shorter duration. Even after 2 and 4 days transit period prior to cold storage the fruits of Langra can be kept in satisfactory condition for 35 to 45 days. Hard green fruits of this cultivar after removal from cold storage can be ripened to a satisfactory taste.
