Fungal infection during germination of crop seeds of common problem in agriculture and invtro seed germination studies. In order to evaluation of antifungal effects of thyme (Thymus vulgaris) extract on wheat , maize, soybean and cumin seeds during germination stage an experiment was conducted in Department of Plant Protection, Faculty of Agriculture, Urmia University, Urmia, Iran during 2012. ...

Efficient seed germination and rapid and uniform seedling emergence are important in commercial agriculture. Therefore, the use of strategies to improve germination and seedling establishment is necessary for increasing productivity. Hydropriming has been suggested as a simple pre-germination strategy to improve seed performance. In this study, the effects of different durations of hydropriming...

abstract- this experiment was carried out during the growing seasons of 2010 and 2011 at the agricultural research farm of bu-ali sina university, to study the effect of weed competition on subsequent germination and seed vigour of chickpea. 12 weed interference durations were evaluated in a randomized complete block design with three replications. experiments consisted of two sets of treatment...

In order to investigate the effect of seed inoculation with Plant Growth Promoting Rhizobactria (PGPR) on germination and some biochemical and physiological indices of Cumin (Cuminum cyminum L.) under salinity stress, an experiment was conducted. Experimental factors were included in seed priming in five levels (seed inoculation with three strains of Pf2, Pf25 and CHA0 of Pseudomonas fluorescen...

Ferula ovina is one of forage species of Isfahan and Chaharmahal va Bakhtiari whose natural spreads are under destruction. Finding information about its seed dormancy, effective factors in the dormancy breaking and also about optimal conditions of seed germination is necessary for recovery of this plant spreads. To actieve that goal, two factorial experiments were performed in completely random...

The use of plant-based systems to remediate contaminated soils has become an area of intense scientific study in recent years and it is apparent that plants which grow well in contaminated soils need to be identified and screened for use in phytoremediation technologies. This study investigated the effect of diesel fuel on germination of selected plant species. Germination response varied great...

Nowadays, in many rangelands, due to over grazing, and problems that some plantshave in germination, the rate of forage production is greatly reduced. So to take advantages ofthe benefits of such plants, it is necessary to identify and remove barriers of germination andestablishment of suitable plants. The present study was designed to investigate differenttreatments of breaking dormancy and st...
