Leafy spurge (Euphorbia esula L.) is a noxious perennial weed that produces underground adventitious buds, which are crucial for generating new vegetative shoots following periods of freezing temperatures or exposure to various control measures. It is also capable of flowering and producing seeds, but requires vernalization in some cases. DORMANCY ASSOCIATED MADS-BOX (DAM) genes have been propo...

Underground dams are structures that block the natural flow of groundwater and causes underground water resources. In this study, at first18 prone area stounderground Dams were identified using Boolean logic and geology parameters, land use, slope, distance from roads and distance from fault. In the discussion of underground dams, subsurface flow has high importance so that if there is not suit...
