Seed germination has an important role in the life cycle of plants and critical stages of the growth cycle, establishment and final yield. Seed germination is the most critical stage of seedling establishment which ultimately determines the successful production of the product. Salinity is one of the environmental factors reducing crop production in the world. Saline soils or irrigation the...
In order to evaluate salt tolerance in seedling stage, seeds of 11 hybrid and new varieties of cotton, compared to commercial cultivars of Golestan as control were planted in pot. Factorial experiment in a completely randomized design with three replications was conducted at the Cotton Research Institute of Iran in 2014. The first factor was salinity levels and the second factor was 12 genotype...
In order to evaluate the interaction of rice genotypes to salinity stress, responses of 16 rice genotypes were assessed to 4 salinity levels (0, 4, 8, 12, dS/m) through a split plot experiment seedling stage in hydroponic culture. In this experiment characters such as plant height, leaf area, root length stem length, dry weight of root and stem, dry weight of leaf and total biomass were measure...
This research had conducted to investigate light intensity effects on the lucky bamboo growth in Islamic Azad University, Abhar Branch. The experiment arranged as a complete randomized block design with five treatments (0.75, 1.14, 1.89, 2.29 and 4.09 mmol m-2 s-1) in ten replications. Results showed that 1.89 mmol m-2 s-1 had significant differences than other treatments. The higher level of r...
Drought is a major abiotic stress factor limiting maize production, and elucidating the genetic control of root system architecture and plasticity to water-deficit stress is a crucial problem to improve drought adaptability. In this study, 13 root and shoot traits and genetic plasticity were evaluated in a recombinant inbred line (RIL) population under well-watered (WW) and water stress (WS) co...
The research has been done for assessment of effects of different concentrations of Indole-3-Butyric Acid (IBA) on rhizogenesis of scions of C. Phlomidis in 2010. The research has been done on Randomized Complete-blocks for five replications and three treatments with zero, 2000ppm and 3000pmm concentration. Different characters such as number of root of each scion, length of root, length of ne...

The aim of the present study was to determine effects of artificial drought stress on the characteristics of germination and seedling growth in bread wheat cultivars. The material of experiment consisted of seeds obtained from eight bread wheat cultivars with different response to drought (Alpu 2001, Sultan 95, Konya 2002, Eser as sensitive cultivars; Karahan 99, Tosunbey, Kate A1 as resista...
We have identified certain heat-resistant (HR) and heat-sensitive (HS) lettuce (Lactuca sativa) recombinant inbred lines (RILs) from 113 lines under hot ambient temperature by studying the root morphology, shoot and root productivity. Except for temperature, one of the other major determinants of root morphology is nitrate (NO3 ) availability. In this study, total productivity, root morphology,...
