English Abstract
Sumac (Rhus coriariaL.) is a deciduous shrub growing 3 to 6 m.
height, belongs to genus Rhus and family Anacardiaceae.
Sumac is a very popular in the Kurdistan region of Iraq with a great ecological, economic and medicinal value.
It is well known that the seeds of this species had very low germination percent, because they are undergoing dormancy due to hard seed coat and physiological dormancy as well.
So, it was necessary to subject seeds before sowing to some of pre- treatments for breaking dormancy phase and then sowing them in a suitable growing media, to fulfill this purpose, this experiment was conducted in Malta forest nursery- Duhok/Kurdistan regionofIraq, during the period from late February to May,2014, to investigatethe impact of scarification by concentrated sulfuric acid (H2SO4) and sowing media on breaking dormancy and increasing seed germination.
The experiment comprised studing the effect of two factors: First, soaking seeds in conc.
(H2SO4) for the periods (0, 1, 2, and 3) hours.
Second, three types of sowing media included: river sand, river sand + building sand (1:1) and river sand + building sand + Peat moss (1:1:1) in plastic pots under field condition in a factorial experiment (4*3), using randomized complete block design (RCBD).
The results showed that both soaking periods in conc.
(H2SO4) and sowing media and the interaction between them significantly increased germination of seeds attained (29.6%) with soaking seeds in conc.
H2SO4 for 3 hours and (20.97%) in sowing media consisting of river sand + building sand (1:1).While the interaction between the two factors revealed synergistic effect and gave the best result of seed germination achieved (40.7%) was found in seeds treated with conc.H2SO4(98%) for 3 hours and seeded inriver sand + building sand (1:1).
