salinity stress is a major limitation in wheat production. the lack of economically viable methods for screening salinity tolerance in field is an obstacle to breeders. in this study a population of 254 recombinant inbred lines (rils), derived from a cross between roshan × sabalan was assessed in glasshouse during the seedling phase in order to identify quantitative trait loci (qtls) for salini...

The influence of pre-sowing treatments using hydropriming, osmopriming and halopriming in laboratory and/or nursery tests on seedling emergence, seedling weight and plant growth of endive and chicory was examined. Halopriming (KNO3) or growth regulators (gibberelic acid; GA3) improved the rate of germination of endive and chicory and reduced the mean germination time needed. 30 min pre-sowing t...

An experiment was conducted at Indian Agricultural Research Institute, New Delhi to study the effect of pre-sowing seed treatment using different combinations of magnetic field intensities and time duration, on germination and seedling attributes in North Indian variety of tomato (var. Pusa Ruby). Seeds were exposed to static magnetic fields (SMF) of strength 50, 100 and 120 mT for 5, 10, 15, 2...

Successful tree regeneration requires both successful seedling establishment and subsequent survival and growth suf®cient to ensure recruitment. We examined patterns of initial seedling establishment in randomly selected stands of eastern hemlock (Tsuga canadensis) distributed across northern Wisconsin and eastern Upper Michigan. In 1990, we counted all hemlock seedlings (de®ned as 4±29 cm tall...

abstract heterotrophic seedling growth has described as the product of the following dynamic and to transmit seed reserves and the conversion efficiency of mobilized seed reserves to seedling tissue. this research was carried out to evaluate germination and seedling growth of wheat seed (n8019) in the form of combined analysis design with crd arrangement. treatments consisted of 4 levels of wat...

1 We examined amongand within-species effects of seed mass for seedling establishment from seed to 5 years of age in a field experiment at Paracou, French Guiana. 2 Six seeds of each of eight species were weighed and planted into each of 120 plots (1 m 2 ) throughout closed-canopy forest along 12 100-m transects in 1998. 3 We described the microhabitat of each planting site using principal comp...

This study was conducted at the Gorgan University of Agricultural Sciences and Natural Resources farm, Iran, Golestan province with about 600 mm annual rainfall in order to evaluate the effect of different sowing dates on Azivash (Corchorusolitorius) seed quality, using a randomized complete block design with three replications on 2013. Treatments were four sowing dates such as May 5, ...

Some biochemical activities in embryo or seedling of germinating rice (Oryza Sativa L.) seed were studied to explain the effects of suboptimum (20 C), optimum (30 C), and supraoptimum (40 C) temperatures on seed germination and seedling growth. It was observed that 40 C slightly speeded up seed germination but severely inhibited the growth of young seedlings, 30 C delayed germination compared t...

The present investigation was carried out to study the induced mutagenesis of EMS (Ethyl methane sulphonate) on the seed germination, seedling survival and LD50 value of Catharanthus roseus. The seeds of Vinca rosea were treated with different concentration of EMS viz., 5, 10, 15, 20, 25, 30, 35, 40, 45 and 50 mM. The untreated seeds were taken as control. The EMS treated and control seeds were...
