To demonstrate the combined toxicity of cadmium (Cd) and arsenate (As) to early developmental stages of six wheat varieties, young seedlings were exposed to solutions containing both contaminants and seed germination frequency and seedling biomass, root length and shoot height, Cd and As uptake, amylase activity, superoxide dismutase (SOD), catalase (CAT), peroxidase (POD), soluble protein and ...
Gaining insights into the germination and emergence patterns of weeds as well as the factors which have an impact on these patterns is beneficial for weeds management programs. In order to investigate the effect of temperature, waterlogging and salinity on germination and emergence of common lambsquarters, three separate experiments were conducted, adopting a completely randomized design with f...
in order to study effect of seed weight on germination and growth of wheat seedling, an experiment in seed technology laboratory of aboureihan paradise university of tehran in 2005 has been done. in this experiment, at first stage, the seeds separated by longitude step, latitude step and set frequency parameters of gravity separator set. in second stage, 10 treatments of 1000 seed weight entere...
Grain yield has a usually the low heritability, consequently to predict this trait it is recommended to use some morphological characters having a high heritability with high correlation with grain yield. To study of relationships between traits and to find out traits having the high influence on grain weight, 36 winter wheat cultivars were planted through a randomized complete block design wit...
In order to study the effect of seaweed extract and nano-ZnO on germination characteristics of tomato seed, a factorial experiment was conducted based on a randomized complete block design. Preliminary germination and seedling growth tests were performed to determine the best concentration of seaweed extract and nano-ZnO. Experimental treatments included three levels of drought stress (0, 2- an...
Six parents of Jatropha curcas were crossed in half diallel fashion, and the F 1s were evaluated to determine the combining ability for nine germination parameters. The ratio between general combining ability (GCA) and specific combining ability (SCA) variances indicated preponderance of additive gene action for all the characters except germination percentage, time of 50% germination, seedling...
High germinability of seeds and establishment of young seedlings in rice (Oryza sativa L.) are necessary for direct seeding in paddy fi elds. We investigated whether germinability and seedling growth were promoted by treatment of rice seeds (cv. Hitomebore) with hydrogen peroxide solution (H2O2) during the imbibition for 24 h. H2O2 treatment with 50 mM H2O2 promoted seed germination, and seedli...
boron tolerance in wheat accessions of different origin estimated in controlled and field conditions
this study was aimed to assess the effects of excess boron on 59 genetically divergent wheat accessions and to identify those with high and stable yields under a range of soil boron concentrations. the second aim was to test the applicability of a laboratory technique performed at juvenile stages of development in estimating field boron tolerance. the study comprised a control and three boron t...
Wedelia trilobata is an invasive weed of the family Asteraceae.Objective study was to find out impact essential oil on germination and seedling growth cowpea. Different concentrations oil(200, 400, 600, 800 1000ppm) were used,a controlwas kept without oil. Cowpea seeds sown in these petriplates,at end test period all parameters measured. All showed that treatment had no negative germination. Wh...
Nursery experiments were conducted to select the suitable bioinoculants with locally available organic source to improve quality seedling production of Jatropha curcas L. Two months old Clones was procured from the Mission Biofuel India Pvt. of Madurai district, Tamilnadu, India. Clones were transplanted in a mixture of UnSterilised sand, Soil, and Farm Yard Manure (FYM) in the ratio of 2:1:1 i...
