Influence of ultrasonic waves and storage period under field condition on germination of four vegetable seeds

الملخص EN

A laboratory experiment in 2014 was carried out in the Central Laboratory of Research, College of Agriculture, University of Duhok.

The aim was to investigate the effect of ultrasonic waves and stored period under field condition on germination percentage of four vegetable seeds : Cress, Celery, Swiss chard and Garden Rocket.

The factors studied were ultrasonic waves power (30 and 60 w) with time of (0,5, 10, and 15 min) of ultrasonic waves and storage period (1 and 2 years).

Completed Randomized Design with four replicates was used.

Results showed all studied factors and its interactions had significant effect on germination percentage of studied vegetable seeds, expect the effect of storage period on germination percentage of Garden Rocket.

The results indicated that there were a significant three way interaction effect of ultrasonic waves power 30 w, duration zero and 1 year storage period on germination percentage of Cress , Swiss Chard and Garden Rocket (99.3, 100.0 and 100.0%) respectively, compared most interactions.

Also, found three way interaction significant effect mention on germination percentage of Celery (73.0 %) when exposed to ultrasonic duration 10 min as compared to other interactions.

It can be concluded that ultrasound led to improve germination vegetables studied, but the duration of storage led to reduce over time.

It can be recommended to treated the seeds with ultrasonic waves at 30 w for zero min in Cress , Swiss Chard and Garden Rocket and for 10 min in Celery to improve the germination percentage of seeds stored for one year.
