seed germination is a crucial stage in the plant life cycle and salt tolerance during germination stage is vital for the establishment of plants in saline soils. in order to evaluation of sesame (sesamum indicum) landraces germination to salinity stress at different temperature, an experiment was conducted at ferdowsi university of mashhad, collage of agriculture during 2009. experimental type ...

Seeds of eight commonly grown bedding plant species [Ageratum houstonianum Mill., Begonia × semperflorens Hort., Impatiens wallerana Hook., Lobularia maritima (L.) Desv., Petunia × hybrida Hort., Pelargonium hortorum L.H. Bailey, Salvia splendens F. Sellow, Tagetes patula] were germinated at pH values from 4.5 to 7.5 at 0.5 increments. Seeds were germinated in petri dishes on filter paper satur...

Improving seed germination rate accelerates early seedling establishment, in turn, enhances plant growth and forage production in rangelands and pastures. Rapid and simultaneous germination of seeds leads to successful plant establishment. The ingoing research aims to deals with effect of SiO2 nanoparticles at concentrations of 0, 5, 20, 40, 60 and 80 mg/l on seed germination rate in Astragalus...

Objective: To evaluate the effect of chemical stimuli on germination and seedling growth of Caper (Capparis Spinosa) under drought stress. Methods: Factorial experiment in a completely randomized design with four replicates per treatment were performed. First factor of priming include three levels of acetylsalicylic acid (300, 200 and 100 mg/L), gibberellic acid levels (500, 250 and 12...

abstract. seeds or plant organs are usually used as the materials for the long-term cryopreservation. the aim of this study is to investigate the possibility of seed cryopreservation of lilium ledebourii (baker) boiss. as an endemic and endangered species because of genetic erosion. to evaluate seed potentials for the cryopreservation, four treatments including vitrification, 30% glycerol, desi...

Seagrasses are important components of global coastal ecosystems, and the eelgrass Zostera marina L. is widely distributed along the Atlantic and Pacific coasts in the temperate northern hemisphere, but limited datum related to the contribution of sexual reproduction to population recruitment have been reported. This study aimed to understand eelgrass sexual reproduction and population recruitm...

weed chemical control has negative results on agroecosystems. therefore, identification of cultivars tolerant to weeds has importance in nonchemical management. so, in this study, the tolerance of some alfalfa cultivars was studied to dodder. anexperiment was conducted at research farm and laboratory of shahed university in 2011. the farm experiment was done as split plot in time in randomized ...

this study was performed in year 2010 to evaluate the effect of locality and date of collection on germination and growth of pimpinella aurea dc. seed. the experiment was a factorial one, based upon a completely randomized design of four replications. seeds were collected from three localities in tehran province (tochal, vardavard and lavasanat), at their initial developmental and fully develop...
