in this study 18 corn hybrids consist of 15 new early and mid mature foreign hybrids and three commercial iranian corn hybrids (ksc704, ksc647 and dc370) as controls were evaluated at two rcbd with three replications at the khorasan razavi agricultural research and natural resources center, during 2008 -2010. results showed that hybrid exp1 and dc370 with 16.5 and 12.1 t.ha-1 were the best and ...

The purpose of these studies was to examine the antiproliferative properties of 16 recombinant human IFN-alpha B/D hybrids against various human tumor lines of different histological origin and to determine whether any of the hybrid molecules possessed immunomodulating activity that could active antitumor properties in peripheral blood monocytes of normal donors. Hybrids with the B domain at th...

twenty local and foreign maize (zea mays l.) hybrids in five different maturity groups were evaluated in mashhad, iran for two years (2007-2009). three planting dates (5th may, 20th may and 5th june) and hybrids were arranged in a randomized complete block design as split plot arrangements, with three replications. the planting dates were in main plots and hybrids in subplots. the results indic...

This paper describes the apatite deposition of chitosan-silicate porous hybrids derived from chitosan and γ-glycidoxypropyltrimethoxysilane (GPTMS) in alkaline phosphate solution. The preparation of porous hybrids with needle-like apatite on their surfaces is described. Following apatite deposition the porous hybrids maintained high porosity. The enzymatic degradation rate was low even after 6 ...

Interest in amylose and its hybrids has grown over many decades, and a great deal of work has been devoted to developing methods for designing functional amylose hybrids. In this context, phosphorylase-catalyzed polymerization shows considerable promise as a tool for preparing diverse amylose hybrids. Recently, advances have been made in the chemoenzymatic synthesis and characterization of amyl...

A hybridization technique for the quantification of nucleic acids is described. In the method a probe pair is allowed to form hybrids with the target nucleic acid in solution. One of the probes has been modified with an affinity label, by which the formed hybrids can be isolated after the reaction. Streptavidin-agarose was used to capture hybrids containing biotinylated DNA. The hybrids were me...

Corn hybrids for silage vary in yield and several quality traits that affect farm profitability, which is the prime criterion on which hybrids should be ranked. The partial budget approach is the only way to rank corn hybrids for silage for individual farms according to their effects on farm profits. Partial budgets consider only those costs and returns that change in response to the corn hybri...

Two field experiments were conducted in 1995-1996 to determine if there are common yield responses among maize hybrids to larval western corn rootworm, Diabrotica virgifera virgifera LeConte injury. Three yellow dent hybrids, five white food grade dent hybrids, and a popcorn hybrid were included in the study. The minimum level of rootworm injury as measured by root damage ratings (3.2-4.2) that...
