Mapping major quantitative trait loci (QTL) responsible for rice seed germinability under low temperature (GULT) can provide valuable genetic source for improving cold tolerance in rice breeding. In this study, 124 rice backcross recombinant inbred lines (BRILs) derived from a cross indica cv. Changhui 891 and japonica cv. 02428 were genotyped through re-sequencing technology. A bin map was gen...
DOR: 98.1000/2383-1251.1397.5.71.9.1.1575.1605 Extended abstract Introduction: Generally speaking, plants contain various organic compounds which could influence the behavior of plant communities. These compounds are basically secondary metabolites which are found in various parts of plants such as rhizomes, roots, stems, leaves, flowers, fruits and seeds. The objective of the present st...
The purpose of this study was to evaluate the effect of Nano TiO2 and Nano CNT on some germination indices and growth parameters of some hulled barley cultivars. The experiment was conducted in a laboratory at Shahrekord University during 2014. The study was a factorial, adopting a completely randomized design with four replications. Treatments consisted of titanium dioxide nanoparticles and ca...
In the present study, 150 accessions of worldwide originated durum wheat germplasm (Triticum turgidum spp. durum) were observed for major seedling traits and their growth. The accessions were evaluated for major seedling traits under controlled conditions of hydroponics at the 13th, 20th, 27th and 34th day-after germination. Biomass traits were measured at the 34th day-after germination. Correl...
Extended Abstract Introduction: Weeds, as the most important biological stress, reduce the efficiency of water use, waste of food, shading and secretion of toxic substances, leads to a 10 to 100 percent reduction in crop yields. The first step of the weed control understands the biology and life cycle of the weed particularly seed Eco physiological characteristics. Dormancy in weed seeds, incl...
germination response to temperature is different among plant seeds. germination rate and percentage is maximal at optimum temperature (s), and then reach to zero at base and ceiling temperatures. the objective of this research was (1) to evaluate germination response of snail medic seeds to temperature and (2) to determine cardinal temperatures of germination rate and percentage. therefore, see...
In order to investigate the effect of drought tension on germination characteristics and seedling growth of 10 alfalfa genotypes, two separate experiments were carried out in vitro petri dish culture medium (seed testing) and potting (vegetative growth stage) as a factorial experiment in a completely randomized design with three replications in a specialized laboratory in Khuzestan University o...
This experiment was conducted as a factorial experiment based on a completely randomized design with three replications at two locations: Agricultural and natural resource center of Ardebil province (Moghan) and seed and plant certification and registration institute of Karaj in 2013. The treatments included: planting date in three levels (10-May, 25-May and 9-Jun), seed moisture content at har...
in order to study the effect of foliar application of zinc and iron on germination of soybaen seed under different level of irrigation, an experiment was conducted in 2009 at shahrekord agricultural research center. main factor was including of four levels of drought stress as irrigation (irrigation after 60, 80, 100 and 120 mm evaporation from class a evaporation basin) and sub factor was inc...
Corn productivity in Indonesia is still relatively low compared with other countries. Therefore, it necessary to increase the of corn by using rhizobacteria, which have multiple traits. This study was conducted obtain indigenous rhizobacteria Bali that traits, can produce indoleacetic acid (IAA), fix nitrogen from atmosphere, siderophores, colonize roots, seed germination, and promote growth co...
