Wormwood sagebrush (Artemisia sieberi Besser) is one of the most widely distributed shrub species in Iran and Turkistan steppes, its establishment on dry lands has generally been proven difficult because of low seedling vigor, inability to compete with herbaceous species, poor seed quality, and altered edaphic conditions. In order to evaluation of planting methods and […]
The use of metal-accumulating plants to clean the contaminated soil with toxic metals is the most rapidly developing component of phytoremediation as an environmentally friendly technology. Overcoming harsh soil conditions and accelerating the recovery of degraded soils remain a worldwide restoration challenge. This study evaluated the effect of different concentrations of Pb, Zn, Cu and […]
Considering forage grass species, germination is one of the important stages concerning the growing stage that is often influenced by environmental stresses, particularly salinity and drought stresses. Thus, this study aims to assess the effects of salinity and drought stresses on germination characteristics and seedling growth of desert wheatgrass, Agropyron desertorum (Fisch. ex Link) Schult. […]
To study the effects of chilling on dormancy breaking and the increased germination characteristics of Nepeta (germination percent and speed, seedling length, vigor index, wet and dry weight), a factorial experiment in a completely randomized design with 4 replications was implemented in a laboratory in 2014. Factor A was the chilling treatment in three levels […]
Improving seed germination rate accelerates early seedling establishment, in turn, enhances plant growth and forage production in rangelands and pastures. Rapid and simultaneous germination of seeds leads to successful plant establishment. The ingoing research aims to deals with effect of SiO2 nanoparticles at concentrations of 0, 5, 20, 40, 60 and 80 mg/l on seed […]
Common burnet (Poterium sanguisorba) is a perennial herb from rose family (Rosaceae) which is used to construct pastures. The studied plant can resist against freezing, cool and drought. The present study was conducted to study the seed germination parameters of common burnet in different thermal treatments as completely randomized design in 4 replications in 2013. […]
Germination represents a fundamental stage of plant life highly responsive to change of environmental conditions. Low germination percent and seedling establishment are basic problems in saline regions. One of the sensitive stages of plants to salinity is the germination stage. This study was conducted using a factorial experiment with three factors such as species with […]
The study was conducted to collect germplasm and identify appropriate seed treatment technique to enhance germination of Bouffordia dichotoma syn. Desmodium dichotomum, which is self-generating wild legume forage growing in eastern Amhara (North Wollo, South Wollo and Oromia Special Zones), Ethiopia. Twenty six Desmodium dichotomum seed populations (1000 seeds from each) were collected in 2018 […]
A part of plant species composition in natural ecosystems is live seeds that are hidden in the soil and known as soil seed bank. Detecting this species resource has a key role in protecting and restoring the vegetation. The present study aims to investigate the soil seed bank and its relationship with the aboveground vegetation […]
Native palatable species are the most important plants for the restoration of arid areas. Zygophyllum atriplicoides is one of the useful species in restoring arid regions, but poor germination and seedling growth are the main problems in the establishment of this species. The objective of this study was to investigate the effect of biological, chemical, […]
