Effect of peganum harmala on seed germination, seedling growth and calcium potassium content of triticum aestivum and hordeum vulgare

Abstract EN

This study was designed to investigate the effect of the water extract of harmal (Peganum harmala) seeds on germination , seedling growth and Ca++ and K+ ions concentration of wheat (Triticum aestivum) and barley (Hordeum vulgare).

It showed that the aqueous extracts of P.

harmala seeds inhibition the germination, while the extracts increased the shoot length of T.

aestivum and H.

vulgare but this extracts decreased the root length of test species and increased the dry weight of the shoot, while decreased the weight of roots of the test species.

The concentration 0.2 % increased significantly the concentration of the potassium (k+), while both concentrations (0.2 %, 0.4 %) cause insignificantly Decreased in potassium and calicium concentration.

The inhibitory effect on seed germination, the length and dry weight of shoot and root of test species were increased proportionally with increasing extract concentration.

But the increase in shoot length and the concentration of k++ ion in T.

aestivum occure only in concentration 0.2 %.
