A doubled haploid (DH) population of barley (Hordeum vulgare L.) generated from salinity tolerant genotype CM72 and salinity sensitive variety Gairdner was studied for salinity stress tolerance at germination, seedling emergence and first leaf full expansion growth stages. Germination study was conducted with deionized water, 150 mM and 300 mM NaCl treatments. Seedling stage salinity tolerance ...

According to the importance and diversity of Chenopodium album, Cynodon dactylon and Amaranthus retroflexus in safflower fields and significant role of safflower (Carthamus tinctorius L.) as an oil seed, an experiment was conducted using CRD based factorial design with three replications to study the allelopathic effects of root and shoot extracts of these weeds on germination and early growth ...

today, the production of healthy and high quality seedlings is the main factors of success in growing vegetables such as tomato. hence, in order to investigate the effect of different levels of vermicompost and nitrogen on the growth parameters of tomato seedlings (lycopersicon esculentum mill. cv. rio grande), a factorial experiment was conducted in a randomized complete design with three repl...

the effect of electromagnetic field was examined on zinnia (zinnia elegans) seeds to enhance seed germination and early growth. the seeds were exposed to four magnetic strengths of 15, 100, 400 and 800 mt in four durations of 30, 60, 120 and 240 min. the experiments were carried out in two forms of laboratory germination and soil emergence. results showed that magnetic field application enhance...

recently, increase in crop production depends on better seedling establishment, emergence rate and uniformity. thus, an experiment was carried out in a randomized complete block design with 8 fertilizer treatments and 4 replications in 2008 at sari agricultural sciences and natural resources university. the aim of this research was to evaluate effect of vermicompost (vc) on bush bean seedling e...

Drought stress is one of the most important factors limiting plant growth all around the world. Plant Growth Promoting Rhizobacteria (PGPR) can significantly reduce drought stress effects on plants growth. This study was aimed to investigate the influence of PGPR (inoculation by Azospirillum lipoferum, Azotobacter chroococcum, Pseudomonas aeruginosa, and Bacillus cereus) on seed germination, se...

Penicillium spp. produce a variety of beneficial metabolites for plant growth and survival, as well as defend their hosts from attack of certain pathogens. In present study 20 Penicillium spp. culture filtrates were screened for growth activity in wheat seedlings. Germination percentage of wheat seeds was enhanced by Penicillium spp. culture extracts. Although, the most active inhibitors of see...

abstract suitable seedling is one of the most important factors of onion growth and yield in transplanting method (tm). in order to investigation effects of different seedling size and age on marketable yield , biological yield, harvest index and some qualitative characters in onion an experiment was couducted at the agricultural research center of east azarbayjan in 2008. the factorial was con...

The effect of cement dust on the growth parameters of brinjal (Solanum melongena) was studied. The cement dust (2 g/plant) exhibited both inhibitory and promotory effects on different growth parameters of the S. melongena. The decrease in the number of leaves (37.19 and 62.28%), leaf area (57.93 and 57.26%), root length (48.21 and 56.75%), shoot length (27.27 and 38.98%), plant circumference (3...
