for finding out the effect of nitrogen and calcium carbonate fertilizers on nitrate and nitrogen accumulation in aboveground biomass, calcium concentration and dry weight of leaves of satureja hortensis l., a factorial experiment was carried out based on randomized complete block design with three replications in karaj in 2008. the nitrogen fertilizer was in four levels (0, 50, 100 and 150 kg. ...

To probe variation in Al sensitivity of two co-occurring pine species, seedlings from six full-sib families of loblolly pine (Pinus taeda L.) and slash pine (Pinus elliottii Engelm.) were grown in solution culture containing 4.4 mM (high-Al) or 0.01 mM (low-Al) AlCl(3) at pH 4 for 58 days. On average, both pine species had 41% less total dry weight in the high-Al treatment than in the low-Al tr...

The study was conducted to evaluate the effect of dietary dry fat inclusion on reproductive performance of Shami goats. Forty-five dry Shami goats (2 4 years of age, 64 kg body weight) were selected and divided randomly into 3 groups of 15 goats each in a completely randomized design. Treatments started 45 days before mating using one of three total mixed rations (TMR): 0, 3, or 5% of dry fat. ...

loads in bullfrog sympathetic ganglion neurons. The articles include measurements of ER total [Ca] made within individual cisternae identified in cryosections from rapidly frozen cells, using energy-dispersive X-ray microanalysis. Use of the perforated patch recording technique (which avoids the cytosolic dialysis produced by whole-cell recording) allowed an impressive degree of stability in th...

effects of morph physiological characteristics on yield and yield components of corn grain were investigated. an experiment was conducted in the experimental field of abourayhan campus, university of tehran. the experimental design was a block in split plot arrangement with four replications. planting dates were as main factor with three levels (4th, 14th and 25th june) and four varieties (sing...

Hydrochloric acid extraction of feces in the presence of ether yields an extract suitable for spectrophotometric estimation of total porphyrin and for further separation by "high-performance" liquid chromatography (HPLC) or thin-layer chromatography. A total porphyrin reference interval of less than 200 nmol/g dry weight of feces was established from data on 106 normal subjects on an unrestrict...

The postharvest treatments included control, low temperatures (14 and 18°C) and plastic bags with or without perforations. Changes in different physico-chemical characteristics of fruits were studied during storage. The two factor experiment was laid out in completely randomized design with three replications of 10 fruits. Among the physico-chemical parameters, colour, firmness, total weight lo...

The ontogeny of carrots (Daucus carota cv. 'Spartan Premium') grown under greenhouse conditions in pots of organic soil infected with Meloidogyne hapla was influenced detrimentally as early as 4 days after seeding, as determined through analysis of plant surface area, dry weight, fresh weight, net assimilation rate, relative growth rate, and leaf-area ratio. Only 58% of the diseased carrots wer...
