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 germination rate in Astragalus...

Kelussia odoratissima Mozaff. belonging to the Apiaceae family, is well known for its medicinal and nutritional importance, endemic to Iran. Seed dormancy is a major problem present in Kelussia odoratissima leading to low germination percentage; thus, improvement of seed germination and breaking seed dormancy is important. Piriformospora indica, a root-colonizing endo...

there are some computer programs to calculate germination related traits such as germin which have using problems. the aim of this work was to adjust germin for calculating germination related traits. seed aging effects on the seedling emergence was modeled using the optimized germin. this study was conducted based on completely randomized design in a factorial combination of five seeds aging t...

The use of local seed provenances is often recommended in restoration and habitat creation because they are thought to be better adapted to local habitat conditions. However, spatial scales and the degree of population differentiation are not well known and germination is often not included in comparisons between provenances. We analysed germination as a key trait of plant development in five p...

In order to investigate the effects of priming methods on the improvement of seed germination indices and seedling growth of Lallemantia (Lallemantia Iberica) under different salinity levels, two factorial experiment in a randomized complete block design were carried out in the seed technology laboratory of Agricultural Sciences and Natural Resources University of Khuzestan in 2018-2019. In the...

Pyrethrum is a perennial daisy grown commercially for the insecticide that is extracted from its flowers. In order to evaluate germination and seedling growth of pyrethrum under different temperature and drought stress treatments, an experiment was conducted in seed technology laboratory of Faculty of Agriculture of Islamic Azad University of Isfahan branch in 2018. During this experiment, poly...

A laboratorial study was carried out to investigate the effect of NaCl priming on seed germination and seedling growth of canola. Canola seeds were primed with 1% NaCl solution for 24 hours, at 20°C. Then primed and non-primed seeds were irrigated with seven different saline solutions consisted of 0 (control), 0.25, 0.50, 0.75, 1.00, 1.25 and 1.50% concentrations of NaCl. Results indicated that...

The genetic basis of seed germination and seedling vigor is largely unknown in Brassica species. We performed a study to evaluate the genetic basis of these important traits in a B. rapa doubled haploid population from a cross of a yellow-seeded oil-type yellow sarson and a black-seeded vegetable-type pak choi. We identified 26 QTL regions across all 10 linkage groups for traits related to seed...

to investigate effects of temperature and salinity different levels on germination parameters of german chamomile (matricaria chamomilla), an experiment carried out in complete randomized design as factorial with three replication in department of agronomy, college of agriculture on the university of guilan, in 2014. treatments were including temperature levels (5, 10, 15, 20, 25, 30 and 35 oc)...
