Description The present experiment was conducted in a CRD with three replications to study the
effect of different priming agents in improving the seed quality parameters of solanaceous
vegetable crops like tomato, brinjal and chilli. Fresh seeds of four tomato, four brinjal and
two chilli varieties were treated with GA3 (1 ppm), KNO3 (5%), Na2HPO4 (2%), PEG (10%),
ZnSO4 (1%), Ascorbic Acid (50 ppm) and Deionised H2O for 24 hours and then dried to
original moisture content under shade. Dried seeds were taken as control. Observations were
recorded on germination/field emergence, root length, shoot length, seedling length, seedling
dry weight, seedling vigour index-I & II in both lab and field tests. The results revealed that in
tomato, GA3 ranked first in increasing germination percent, dry weight, SV-I, SV-II, FEP, and
SV-I of FES (field emerged seedling); KNO3 ranked first in increasing shoot length and SV-II
of FES; Na2HPO4 ranked first in increasing seedling length; and PEG ranked first in
increasing root length as compared to control. In brinjal, GA3 ranked first in increasing
germination percent, SV-I and FEP as compared to control; KNO3 ranked first in increasing
shoot length, dry weight, SV-II and SV-I of FES over control; Na2HPO4 ranked first in
increasing root length and seedling length; and ZnSO4 ranked first in increasing SV-II of
FES as compared to control. In chilli, GA3 ranked first in increasing germination percent,
shoot length, seedling length, SV-I and FEP in comparison to control; KNO3 ranked first in
increasing dry weight, SV-II and SV-I & SV-II of FES; Na2HPO4 ranked first in increasing
root length; and ZnSO4 & PEG also ranked first in increasing dry weight as compared to
control. The efficacy of priming treatments was expressed in terms of seed quality index
(SQI). Seed quality index pooled over the three solanaceous vegetable crops indicated that
KNO3 was the best priming treatment followed by Na2HPO4 and GA3.
