Successful germination is the main factor in proper establishment and seedling yield. Information on seed germination, in the face of temperature changes at the time of planting, is a way to identify more suitable cultivars for cultivation at the planting site. For this purpose, a factorial experiment was performed based on completely randomized design with 3 replications. This experiment was c...
to evaluate germination and seedling growth of safflower an experiment carried out as factorial with two factor; temperature (5, 15, and 25 °c) and salinity of sodium chloride (0, 5, 10, and 15 ds/m) based on randomized complete block design with four replications, in dept. of horticulture of urmia university. results of different concentration sodium chloride on germination and seedling growth...
Considering forage grass species, germination is one of the important stagesconcerning the growing stage that is often influenced by environmental stresses,particularly salinity and drought stresses. Thus, this study aims to assess the effects ofsalinity and drought stresses on germination characteristics and seedling growth of desertwheatgrass, Agropyron desertorum (Fisch. ex Link) Schult. in ...
Phytotoxic activity of Ocimum tenuiflorum (Lamiaceae) plant extracts was investigated against the germination and seedling growth of cress (Lepidium sativum), lettuce (Lactuca sativa), alfalfa (Medicago sativa), Italian ryegrass (Lolium multiflorum), barnyard grass (Echinochloa crus-galli), and timothy (Phleum pratense) at four different concentrations. The plant extracts at concentrations grea...
in order to study the interaction of temperature and salinity on seed germination and seedling growth of cucumis melo a factorial experiment was conducted based on crd with four replications. the factors included four temperature levels (25, 30, 35 and 40 °c) and five salinity levels (0, -0.2, -0.4, -0.6 and -0.8 mpa). germination rate and percentage, shoot length, root length, seedling vigor i...
The first experiment was performed to evaluate the effect of vermicompost extract (20, 40, 60, 80, 100%) on seed germination and seedling growth of Plantago psyllium. In second experiment, the effect of solid vermicompost with 4 levels (0, 25, 50, 75) on the emergence and subsequent growth of plantlets was investigated. The 20 and 40% increased germination capacity, germination index, and lengt...
Water deficit is a common and major constrain for agricultural production in arid and semi-arid parts of the world like Iran, to the extent that it might threaten the nation’s food security in years to come. Seed germination is a crucial growth stage that is often affected by environmental stresses, including drought. This study investigated the effects of four levels of water potential (i.e. 0...
The present laboratory experimental study was conducted to evaluate the allelopathic potential of Tinospora cordifolia (Willd.) Miers on seed germination and seedling growth of weed plants (Chenopodium album L. Chenopodium murale L., Cassia tora L. and Cassia sophera L.). Root and aerial root aqueous extracts of Tinospora at 0.5, 1.0, 2.0 and 4.0% concentrations were applied to determine their ...
BACKGROUND AND AIMS GPT2, a glucose 6-phosphate/phosphate translocator, plays an important role in environmental sensing in mature leaves of Arabidopsis thaliana. Its expression has also been detected in arabidopsis seeds and seedlings. In order to examine the role of this protein early in development, germination and seedling growth were studied. METHODS Germination, greening and establishme...
Arabinogalactan-proteins (AGPs) are a family of highly glycosylated hydroxyproline-rich glycoproteins present throughout the plant kingdom. A synthetic chemical reagent, (beta-D-Gal)3 Yariv reagent, specifically binds AGPs and can be used for histochemical staining, isolating and probing the function of AGPs. Here, the role of AGPs in tomato (Lycopersicon esculentum Mill. cv. UC82B) seed germin...
