In order to study the effect of seaweed extract and nano-ZnO on germination characteristics of tomato seed, a factorial experiment was conducted based on a randomized complete block design. Preliminary germination and seedling growth tests were performed to determine the best concentration of seaweed extract and nano-ZnO. Experimental treatments included three levels of drought stress (0, 2- an...
The germination percentage of Acacia catechu Willd. seeds were tested with four pre-sowing treatments in the nursery of Bangladesh Forest Research Institute and growth performances of seedlings were determined both in nursery and field conditions. The germination test was conducted both in germination tray and nursery bed filled with mixture of soil and decomposed cow dung at a ratio of 3:1. Th...
Variation in seed weight is common within and among plant species, but few studies have attempted to document the pattern of seed weight and germination attributes for aquatic macrophytes at a large scale. This study examined within-species variation in seed weight and germination attributes and the effects of environmental factors on seed traits of the submerged plant Potamogeton pectinatus in...
to evaluate the germination traits and mechanical damage of soybean seed during processing stages, anexperiment was conducted in a factorial experiment based on completely randomized design with 18treatments at mazandaran province (sari) in 2009-10. the experiment factors included different seedprocessing stages (before cleaning, after elevator, after pre cleaning, after cleaning, after drying ...
in order to study, the effects of drought stress on germination and seedling growth of chickpea genotypes, experiments were carried out on two susceptible genotypes (mcc68, mcc448) and two resistant genotypes (mcc392, mcc877). in the first experiment the seeds were sown under different levels of drought stress (0,-0.4,-0.8,-1.2mpa) in 25◦c at the growth chamber with 4 replication. the results s...
this study was carried out in order to determine the effects of boron and cold stress on pollen germination of almond hybrids in vitro culture, two different media including the absence and presence of boron (0 mg/l, and 100 mg/l) in 10% sucrose and 1% agar medium at 24°c in dark conditions. the results showed that different treatments had a significant effect on the germination percentage. the...
To study the effects of halopriming and hydropriming in overcoming salt and drought stress in corn (Zea mays L.),two experiments were separately conducted at Shahrood University of Technology. Seed treatments consisted ofcontrol (untreated seeds), soaking in distilled water for 32 h (hydropriming), and soaking in 50 mmol solution ofCaCl2 for 16 h (halopriming). Germination and early seedling gr...
environmental stresses especially drought stress affect on the different aspects of plant growth and cause decrease and delay in germination, decrease of aerial parts growth and decrease in dry matter production. in order to study the effect of drought stress on germination and seedling growth of roselle (hibiscus sabdarifa) medicinal plant, this experiment was conducted in a randomized complet...
one of the important issues in the arid and semi-arid regions is the water deficit and soil salinity. therefore, selecting tolerant species to salinity and drought especially in seed germination and emergence stage is important. in the present study the effects of drought and salt stress on seed germination of vetch (vicia villosa l.) which is palatable forage was investigated. the germination ...
Bromus danthoniae Trin. is an annual grass species that is well adapted to harsh climates and could be considered as an important genetic resources for tolerance to environmental stresses such as salinity. In this study, 24 genotypes collected from Ilam, Kurdistan, Kermanshah (non-saline areas) and West Azerbaijan (saline area: shores of Uremia Salt Lake) provinces of Iran were investigated at ...
