Abstract
Large amounts of saffron petals are disposed off every year while using them as an organic source can open a new approach on reusing them.
In order to investigate the stimulatory or inhibitory effects of saffrons petals on the emergence of wheat, an experiment was conducted on the basis of a complete randomized design with four replications in 2008 in the Dryland Research Station of North Khorasan. 5% concentration of saffron petals water extract (50 grams oven dried petals in 1000 ml water) was used to prepare 5 levels of treatment (0%, 25%, 50%, 75% and 100%). These treatments were used to irrigate wheat seeds (20 ml each day), which were planted in plastic pots and were kept at 25°C in a germinator.
Seedling height increased in 25% treatment significantly.
Different concentrations had significant effects on seedling weight and the best result was obtained from the 25% treatment.
The lowest height and also the lowest weight were observed in the 100% treatment which can be related to the suppressive effect of high concentration of saffron petals extract.
On the other hand, because of the better growth rate obtained from the 25% treatment compared with the 0% treatment, it seems that a low concentration of saffron petals water extract promoted wheat seedling growth.
