Successful crop production depends initially on the availability of high-quality seed. By 2050 global climate change will have influenced crop yields, but will these changes affect seed quality? The present review examines the effects of elevated carbon dioxide (CO2) and temperature during seed production on three seed quality components: seed mass, germination and seed vigour. In response to e...
in order to investigation the effect of row spacing and seeding rate on alfalfa (medicago sativa l. cv. mesasirsa), an experiment was carried out at the research farm of khouzestan agricultural research center from 2000 to 2004. this research was conducted in the form of a split plot design in a randomized complete block, with four replications. main plot was three row spacings (50, 60 and 70 ...

We compared the implant quality of intraoperatively built custom-linked (IBCL) seeds with loose seeds in permanent prostate brachytherapy. Between June 2012 and January 2015, 64 consecutive prostate cancer patients underwent brachytherapy with IBCL seeds (n = 32) or loose seeds (n = 32). All the patients were treated with 144 Gy of brachytherapy alone. Brachytherapy was performed using a dynami...
A southwide eficacy test of reduced rates ofa:inphosmethyl (GuthionB)for control of seedand cone insects in loblolly pine seed orchards was conducted in 1992. In each of nine loblolly pine (Pinus taeda L.) seed orchards, an untreated (no protection) check and two ofjivepossible.rates of Guthion@ (1.0, 1.5,2.0, 2.5, or 3.0 lb ai/ac/application) were randomly assigned to three test plots. Insecti...
An experiment was carried out to evaluate the effects of irrigation levels, based on fraction of the class A Pan evaporation 0.8, 1.00 and 1.20% of ECA and spraying of different amount of salicylic acid (250and 500 Mm) and sprmine (10 Mm And 1 mm) on grain yield and seed quality characteristics of castor bean in during 2012 seasons. The experiment was split plot as randomized completed block d...
In order to assess seed deterioration of soybean at Ardebil province, this study was conducted as a factorial experiment based on randomized complete block design in 2014. The treatments consisted of germination ability, seed moisture content and seed storing conditions. Germination ability treatment was concluded of three germination levels: 80%, 85% and 90%. Also, three rates of seed moisture...
