Some Biochemical Changes in Relation to Loss of Seed Viability in CauliOower Gennplasm

Abstract

Nine culti~'ars of cauliflower were evaluated for seed longevity by accelerated
ageing test (40°C, 90% RH). Six cultivars viz., Early Patna, Early
Kumvari, Super Snow Ball, Alert, Poosi and Early Cauliflower were found
to be good storer and capable of withstanding high storage temperature and
relative humidity. Cultivars Aghani and Snow ]Jail were classified as
moderate and Early Dawn as poor storer. The leaching of electrolytes,
soluble sugars, amino acids and reduction of tetrazolium salt was more
from seeds on deterioration. The quantum of leakage differ among
different genotypes
