Description The present study was carried out on ten genotypes of
coriander (DH-202, DH-205, DH-206, DH-208, DH-228, DH-234,
DH-242, DH-266, Hisar Anand and Pant Haritma with the
objectives to study the effect of natural ageing on seed quality
parameters in coriander by various tests and parameters viz ; test
weight, standard germination test, tetrazolium test, seedling
length, seedling dry weight, electrical conductivity of seed
leachates, speed of germination, vigour index-I, vigour index-II,
dehydrogenase activity test and field emergence index and, to
determine the association of various seed quality parameters with
field emergence. The viability and vigour of seeds declined to
varying degrees in different genotypes of coriander during
xv
ambient storage. Genotypes DH-208 and DH-266 were found most
promising for various parameters of vigour and viability.
Genotypes DH-205, DH-206, DH-208, DH-266, Hisar Anand and
Pant Haritma retained standard germination above 60 % in the
one year old seed lot.
During natural ageing, the standard germination,
seedling length, dry weight, vigour index-I and vigour-II, viability
percentage and test weight decreased significantly and
progressively with ageing period. The interaction among genotypes
and ageing period was found significant for all the characters
under study except standard germination test, vigour index II and
tetrazolium test (seed viability). The test weight, standard
germination test, vigour index-I, dehydrogenase activity test and
tetrazolium test emerged as reliable predictors of field emergence
index.
