Gaining insights into the germination and emergence patterns of weeds as well as the factors which have an impact on these patterns is beneficial for weeds management programs. In order to investigate the effect of temperature, waterlogging and salinity on germination and emergence of common lambsquarters, three separate experiments were conducted, adopting a completely randomized design with f...
calotropis proceran (asclepidaceae) is an evergreen plant and widely distributed in hormozgan province. this plant has the allelopathic properties including germination inhibition, plumule and radicle growth reduction. in this study the effect of different concentrations (0, 5, 10, 20, 40 and 60%) of dry leaf water extraction of this plant on the germination of cucumber (cucumis sativus), tomat...
Groundnut is an important oilseed, food and feed crop of our country whose productivity is curtailed due to biotic and abiotic stresses. Salinity is one of the important abiotic stresses which affects all stages of groundnut growth and finally the yield. Soil amelioration against salinity is a costly and time-consuming procedure. Alternative strategy is to develop salinity-tolerant groundnut ge...

abstract in order to study the effect of different aqueous shoot extracts of four medicinal plants consist of: basil (ocimum basilicum l.), jimson weed (datura stramonium l.), summer savory (satureja hortensis l.) and meliaceae (melia azedarach l.) on seed germination and seedling characteristics of wild oat an experiment was conducted at faculty of agriculture, ferdowsi university of mashhad o...
Extended abstract Introduction: One of the ways to overcome the limitation of fresh water and lack of sufficient water reserves for agriculture is to use unconventional waters such as seawater. Salinity stress is the most important abiotic stress in seawater application. Identification and planting of salinity tolerant genotypes of a plant species is one of the effective and valuable strategie...
Abamectin is nematicidal to Meloidogyne incognita and Rotylenchulus reniformis, but the duration and length of cotton taproot protection from nematode infection by abamectin-treated seed is unknown. Based on the position of initial root-gall formation along the developing taproot from 21 to 35 d after planting, infection by M. incognita was reduced by abamectin seed treatment. Penetration of de...
Extended Abstract Introduction: The germination stage ensures the durability, establishment, and final yield of plants. The final density of plants per unit area is resulted when the planted seeds germinate fully and with adequate rate. Plants mainly undergo abiotic stresses that are a considerable constraint for agricultural production worldwide. Seed priming is one of the simplest and cheap...
In order to evaluate the response of Tarom-mahali rice mutant lines to salinity in germination stage, study carried out as factorial experiment in a completely randomized design with three replications. Rice genotypes were includind 33 tarom-mahali mutant lines (M6 generation) and Hassani (tolerance), Tarom-mahali, Tarom Jelodar, Binam and IR29 (sensitive) cultivars. Salinity levels were in...
