Spindle trees (Euonymus japonica Thunb.) growing in a polluted environment are less sensitive to gamma irradiation
Background: Spindle trees (Euonymus japonica Thunb.) growing in an industrial complex area containing pollutants is chronically injured thus need to build up their resistance. Antioxidant enzymes and cell membrane stability have been widely used to differentiate stress tolerance. Materials and Methods: Leaves of spindle trees from a clean control area (Kijang) and an industrial area (Onsan) whe...
متن کاملDeficit irrigation for reducing agricultural water use.
At present and more so in the future, irrigated agriculture will take place under water scarcity. Insufficient water supply for irrigation will be the norm rather than the exception, and irrigation management will shift from emphasizing production per unit area towards maximizing the production per unit of water consumed, the water productivity. To cope with scarce supplies, deficit irrigation,...
متن کاملPeach Water Relations, Gas Exchange, Growth and Shoot Mortality under Water Deficit in Semi-Arid Weather Conditions
In this study the sensitivity of peach tree (Prunus persica L.) to three water stress levels from mid-pit hardening until harvest was assessed. Seasonal patterns of shoot and fruit growth, gas exchange (leaf photosynthesis, stomatal conductance and transpiration) as well as carbon (C) storage/mobilization were evaluated in relation to plant water status. A simple C balance model was also develo...
متن کاملApplication of the SWAP model to simulate water-salt transport under deficit irrigation with saline water
The agro-hydrological Soil–Water–Atmosphere–Plant (SWAP) model was calibrated and validated to simulate water–salt transport based on field experiments in an arid region of China. The simulation results show lower soil water content but higher salt concentration under deficit irrigation. Soil water and salinity below 95 cm at 80% evapotranspiration (ETc ) treatments and 65 cm at 60% ETc treatme...
متن کاملWater-saving irrigation strategies affect tuber water relations and nitrogen content of potatoes
The dynamic and static deficit (DDI, SDI), partial root drying (DPRD, SPRD) and full (FI)irrigation strategies were applied in Agria and Ramos potato cultivars in a semi-arid area. FIreceived 100% of the potential evapotranspiration (ET); SDI and SPRD received 75% of ETduring the growth period; DDI and DPRD received 90% of ET in the first third, 75% of ET inthe second third and 50% of ET in the...
