Abstract :
The practical utility of seed pre-treatment is
well documented. Seed pre-treatment has been utilized to
improve the germination of different crop species. In the
present study, the effect of pre-treatment of Tomato
(Solanum lycopersicum L.) seeds, which is one of the
important vegetable crops with hydrochloric acid (HCl)
was analysed. Tomato seeds were soaked in distilled water
and two concentrations of HCl (0.03 N and 0.3 N) for three
different time periods i.e., 2 hours, 4 hours and 6 hours.
After the pre-treatment, seeds were sterilized using 5% of
sodium hypochlorite (NaOCl) for 5 minutes. Treated seeds
were placed on the sterilized petri dishes lined with
moistened Whatmann 1 covered with lid. Germinated
seeds were counted every 24 h for 10 days. Data was used
to calculate percentage germination, mean time of
germination and the rate of germination. Results
indicated that percentage germination was improved
significantly when tomato seeds were soaked in 0.03 N
concentration for 2, 4 and 6 hours. Rate of germination
improved with 0.03 N treatment of HCl for a duration of
6 hours. Therefore, an optimum concentration of HCl for
a particular amount of time may have stimulatory effect
on the germination of tomato seeds and can improve the
yield.
