A field experiment was carried out to study the response of presoaked faba bean seeds (Vicia faba cv. Misr 2) in freshly prepared ascorbic acid (50 ppm) or distilled water (control) for 4 hrs at natural environmental conditions, to salinity stress. NaCl treatments caused a reduction in all productivity and yield parameters as compared with control, particularly at high NaCl level (150 mM), wher...

introduction the demand for food and agricultural products are increasing in a line of population increasing in the world (alexandratos, 2003). it is possible to increase the quality and quantity of agricultural products via extending the farms and producing more products (astaaraei and koocheki, 1995). environmental problems caused by synthetic fertilizers and the high levels of producing and ...

in order to study the effect of vermicompost and nitrogen fixing bacteria on seed yield, yield components of seed and essential oil content of coriander (coriandrum sativum), an experiment was conducted as factorial experiment in the base of randomized complete blocks design with eight treatments and three replications at research field of agriculture company of ran in firouzkuh of iran in 2012...

A complete diallel cross using eight flax genotypes including four Iranian breeding lines and four Canadian genotypes was carried out to estimate genetic parameters for days to flowering, days to maturity, plant height, primary branches per plant, number of capsules per plant, number of seeds per capsule, seed yield per plant, 1000-seed weight, seed yield and harvest index. Analysis of variance...

The spatial arrangement of plants in a landscape influences wind flow, but the extent that differences in the density of conspecifics and the height of surrounding vegetation influence population spread rates of wind dispersed plants is unknown. Wind speeds were measured at the capitulum level in conspecific arrays of different sizes and densities in high and low surrounding vegetation to deter...

Canola (Brassica napus L.) is one of the important sources of vegetable oils and protein-rich meals. Canola ranks third in global production of oilseed crops and fifth among economically important crop next to wheat, rice, maize, and cotton. The present work was undertaken with the aim to investigate the effect of Ethylmethyl sulphonate (EMS) on the yield contributing characters of brassica nap...

In healthy forests, vertebrate frugivores move seeds from intact to degraded forests, aiding in the passive regeneration of degraded forests. Yet vertebrate frugivores are declining around the world, and little is known about the impact of this loss on regeneration of degraded areas. Here, we use a unique natural experiment to assess how complete vertebrate frugivore loss affects native seed ra...

Senecio changii (Asteraceae: Senecioneae), a new species from Muli, Sichuan, southwestern China, is described. It is distinguished in Chinese Senecio s.s. by having lyrate-pinnatisect to pinnatisect leaves and a single terminal large discoid capitulum which is somewhat nodding. Evidence from floral micromorphology, karyology and molecular phylogenetic analyses based on the nuclear ITS/ETS seque...

Sir,?I promised in a former letter from here to tell you what Professor Dnnstan said about the daturas from the Federated Malay States. He has just written and says : " The Datura fastiiosa seeds were found to contain 0'39 per cent, of alkaloid, which was proved to consist almost entirely of hyoscine (scopolamine). The Datura alba, seeds only furnished 0*21 per cent, of alkaloid, which was foun...
