seed treatment were superior to other
treatments in controlling the deterioration process and
maintaining the germination (Table 2). This is in
accordance with the reports of Chakravarthy (2004) in
palak seeds. The vigour potential in terms of seedling
growth, dry matter production and vigour index values
determined were relatively higher in seedlings derived
from the seeds treated with Carbendazim+

and stored in aluminum foil pouches than those
form the seeds stored in cloth bags of the present
study (Table 3). The lower value for the vigour
parameters of the seeds in cloth bag might be due to
increase moisture content of the seeds and increased
rate of deteriorative process occurring with the
senescence of seeds due to ageing in storage (Figure
1). Similar results were reported by Menaka (2000)
in amaranthus seeds that were treated with halogen
mixture @ 1.5 g

kg of seeds and packed in
aluminium foil pouches, could be stored safely for
more than 6 months with minimum loss of viability
and vigour.
