Abstract :

Effects of seed coating methods on seed germination of Lathyrus sativus in different moisture stress levels and sowing depths   Nahidi.Mohamad.Bagher*[1], Mehrabi.Hamid.Reza[2], Ariapoor.Ali[3]     Abstract This research performed in order to consider coating ways of seed on germination power of pasture spicy in Lathyrus sativus and variety condition of humidity tensions and planting depth region Borujerd. This model was carried out on factorial experiment and completely accidental of model shape with three repetitions. Present treatment of soil wetness (dryness tension) used in three levels 9%, 14% and 21%of dry soil weight, planting depth treatment in 2levels of third identical seed diameter and sowing in level and covering treatment in four levels of witness without cover(Nc), material with organic base(Oc) material with Hydrogen base(Hc) and material with mineral base (Cc). Above activities were done by using of different tests like variance analysis and Donken multi scopes test. The results among main impacts of treatments on germination percentage showed that, soil moisture percent and sowing depth bad connection less than hundredth in meaningful level. Connection didn’t observe between seed coating with germination percentage of species plant. Triplicate Reciprocal influences indicate that root length has been more in 21% of moisture level, shallow of deep cultivation and 21percent in moisture level, sowing depth triplicate seed diameter in all covering treatments of seed than to 14% and 9% of moisture levels in surface sowing depth and triplicate of seed diameter. In 9%and14% of moisture levels in surface sowing depth indicate that condition didn’t perform or carried out a little in germination percentage factor.   Key Words: Lathyrus sativus, Germination percentage, Moisture tension, Sowing depth.
