Volume 18, Issue 4 , September 2012, Pages 558-568

Abstract
  Environmental stress especially water deficiency (drought) is of the most important factors in arid and semi arid regions of Iran that hugely affects plant growth especially in germination and emergence stages. To find the effects of water stress on germination properties and early growth characteristics ...  Read More

Methods of breaking seed dormancy in Caper (Capparis spinosa L.)

Maryam Makkizadeh Tafti; Ruzbeh Farhoudi; Mohammad Rastifar; Kamal Asilan

Volume 18, Issue 4 , September 2012, Pages 569-577

Abstract
  This study was conducted to study the effect of seed dormancy breaking on seed germination of Caper (Capparis spinosa L.), in a completely randomized design with four replications. Treatments of seed dormancy breaking in Caper included: untreated seeds (control), scarification with concentrated sulphuric ...  Read More

Volume 18, Issue 4 , September 2012, Pages 578-592

Abstract
  Kochia(Kochia scoparia)is an annual halophyte and drought resistant plant that can be irrigated with saline water and has the capability of being used as a valuable source of forage in ecosystems under drought and salinity stress. In order to evaluate germination characteristic of Kochia scoparia under ...  Read More

Evaluation of forage production accessibility with considering effective factors using RS and GIS

Jahan bakhsh Pairanj; Ata... Ebrahimi; Abalfazl Ranjbar; Mohammad Hasan zadeh

Volume 18, Issue 4 , September 2012, Pages 593-607

Abstract
  Evaluation of forage production is an important issue in determining grazing capacity of rangelands. There is no doubt that all forage production in rangelands is not evenly accessible and different factors affect the accessibility of forage. In this research, factors affecting forage availability were ...  Read More
