In order to test the feasibility of computer simulation in field maize planting, the selection of the method of single seed precise sowing in maize is studied based on the quadratic function model Y = A×(D-Dm)2+Ym, which depicts the relationship between maize yield and planting density. And the advantages and disadvantages of the two planting methods under the condition of single seed sowing ar...

the investigation was conducted on wet and dry seasons of ethiopia during the year 2012/2013 at wondo genet agricultural research center nursery site. four levels of cutting size and three levels of cutting positions were arranged in randomized complete block design with three replications. data on seedling height, branch number/seedling, root number/seedling, root weigh/seedling, root length/s...

the phytoremediation capability in pb removal from the contaminated soils by three native seedlings species (acer cappadocicum, fraxinus excelsior and thuja orientalis) and one exotic species (cupressus arizonica) were compared. the seedlings were grown in pb contaminated soils at 0, 100, 200, 300, 400 and 500 mg kg-1 concentrations for 6 months (mar 21 to sept. 22, 2015), after which the bioma...

introductio: hematopoietic stem cell transplants (hsct) are considered as treatment options for patients with solid tumors. transplant numbers have changed significantly over the last decade. we have done autologous and allogeneic hsct for treatment of solid tumor patients in our center. methods: in order to show the transplant effect on solid tumor treatment, we collected data from 71 patients...

liver or hepatic transplantation (lt) is the replacement of a diseased liver with part or whole healthy liver from another person (allograft). human liver transplants were first performed by thomas starzl in the united states and roy calne in cambridge, england in 1963 and 1967, respectively. liver transplantation is a viable treatment option for end-stage liver disease and acute liver failure....

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...

In the hemp-seedling industry, number of leaves on harvested cuttings from mother plants is crucial for survival. Therefore, present study determined suitable hemp (Cannabis sativa L.) to promote adventitious root (AR) formation. Hemp with two, three, and four were apex plant. After disinfecting their base, 18 per replication transplanted into a plug tray (72 holes) filled horticultural substra...

Rice (Oryza sativa L.) is often exposed to cool temperatures during spring planting in temperate climates. A better understanding of genetic pathways regulating chilling tolerance will enable breeders to develop varieties with improved tolerance during germination and young seedling stages. To dissect chilling tolerance, five assays were developed; one assay for the germination stage, one assay...

Following a full mast production in autumn 1995 in the old growth beech forest of la Tillaie, France, cupules, live and dead yearling seedlings were counted in September 1996 in 40 plots, embracing a wide range of ecological conditions. The influence of geomorphology and forest stage on mast production and on seedling establishment and survival was studied. Maximum seedling abundance did not oc...
