Studies were carried out on the microflora of phyllosphere and soil rhizosphere of hulled (Chwat variety) and naked (Akt variety) oats. The material taken for study embraced samples of leaves and soil rhizosphere taken from cultivations differing in extent of nitrogen fertilization. The studies involved determination of total number of aerobic heterotrophic bacteria belonging to the genus Pseud...

The effects of pre-hardening fertilization and autumn on seedling growth have been studied separately, but studies their combined are relatively scarce. We the type level biomass allocation root morphology container-grown seedlings Korean pine (Pinus koraiensis Sieb. et Zucc.), a valuable evergreen conifer distributed from Changbai Mountain to Xiaoxing’an Mountains in northeastern China. Three ...

in order to study effects of nitrogen fertilization and cultivars on some of traits of different barley an experiment was conducted at isfahan in 2012. the experimental was split plot in a randomized complete block design with three replications. in this experiment, different levels of nitrogen in the main plots included four levels (0, 50, 100 and 150 n kg/ha (urea)) and barley cultivars inclu...

We used whole-tree, open-top chambers to expose 13-year-old loblolly pine (Pinus taeda L.) trees, growing in soil with high or low nutrient availability, to either ambient or elevated (ambient + 200 micromol mol-1) carbon dioxide concentration ([CO2]) for 28 months. Branch growth and morphology, foliar chemistry and gas exchange characteristics were measured periodically in the upper, middle an...

This study aimed to develop a protocol of semen cryopreservation of the mutton snapper Lutjanus analis. The interaction between three extenders ( pH 6.1; 7.8 and 8.2) , two concentrations of dimethyl sulfoxide ( DMSO, 5 and 10%) and three cooling rates ( -90; -60 and -30°C.min-1) on the sperm motility rate and motility time were analyzed by a factorial experiment. A sample of 30 fishes ( 1,261 ...
