Analysing pattern of tissue viability loss in seeds of ground nut genotypes differing in dormancy, pre-storage treatment and storage conditions

Abstract

Deterioration of quality in two contrasting groundnut genotypes differing in dormancy (VRI 7, a dormant genotype and CO 7, a non-dormant genotype), seed treatment (halo polymer and iodine impregnation treatment) and storage. Scanning electron microscopic analysis of anatomical changes showed that cells were intact and stable in seeds of dormant VRI 7 whereas cells started smudging showed structural irregularities in non-dormant CO 7. Seeds of dormant genotype VRI 7 subjected to halo polymer and cold storage treatment were found to possess significantly higher viability percentage.
