Standardization of wet acid delinting method for cotton cv. MCU 5

摘要

A study was carried out to standardize wet acid delinting technique for cotton cv. MCU 5 during 2001-2002 at Department of Seed Science and Technology, Tamil Nadu Agricultural University, Coimbatore. It was found that seed recovery, fuzz removal, delinting efficiency, mechanical damage and acidity were increased with increase in quantity of commercial sulphuric acid (H_2SO_4) and contact time (seed to acid). Test weight (100 seed weight) decreased with increase in quantity of acid and delinting tune.The germination percentage and vigour index were increased with increase in acid and contact tune to certain level and then started declining. The results concluded that a concentration of 100 ml of commercial sulphuric acid kg~(-1) and 4 minutes contact duration were found to be optimum for effective declining and maintaining seed quality of MCU 5 cotton.
