Studies on Seed Dormancy and Breaking Methods in Groundnut cv.VRI 7

摘要

The semispreading groundnut variety VRI 7, a hybrid derivative was used to study the dormancy status and breaking methods. The cultivar VRI 7 exhibited dormancy for a duration of 30 days. The fresh kernels were subjected to various dormancy breakingtreatments viz., warm stratification, cold stratification, seed treatment with GA3,ethrel andtheircombinations. Among different dormancy breaking treatments, groundnut kernels subjected to warm stratification was evaluated as the effective treatment forbreaking dormancy and enhanced the seed germination and vigour.
