mihan is a new bread wheat cultivar originated from the cross between iranian cultivar barakat with the chinese cultivar 90-zhong 87 at karaj research station in 1995-96 cropping season. the f1 plants were grown at karaj in 1996-97 cropping season, furthermore f2-f6 populations and regional preliminary yield nursery were evaluated at ardebil agricultural research station during 1997-2003 croppi...

D We investigate the role of commutativity in query processing of linear recursion. We give a sufficient condition for two linear, function-free, and constant-free rules to commute. The condition depends on the form of the rules themselves. For a restricted class of rules, we show that the condition is necessary and sufficient and can be tested in polynomial time in the size of the rules. Using...

plants are potent biochemists; biologically active compounds present in the medicinal plants have always been ofgreat interest to scientists working in this field. thus, the aim of the current study was to screen the antimicrobial activity of acacia nilotica, ziziphus mauritiana, bauhinia variegate and lantana camara against some selected clinical isolated strains. although previous studies hav...

Selenium (Se)-enriched vegetables are promising dietary sources of Se, which provides beneficial biological effects in humans. In this study, we investigated the foliar application Se on hydroponically grown multi-leaf green (V1) and red (V2) lettuce plants. Three selenate (SeIV) amendment levels were evaluated for their influence plant growth, elemental composition radical scavenging capacity....

Orchids are affected by many viruses resulting in poor growth, yield and quality, and an overall decline in population. Cymbidium mosaic virus (CymMV) is one of the common orchid viruses found in Cymbidium species but it infects different orchid genera. In this study Cymbidium aloifolium was propagated in vitro using MS medium at different strength (1.0, ½, and ¼) with or without 0.5 mg/l BAP (...

If n colluding oligopolists all have the cost function C(qi) = c qi, then it will not be possible to uniquely allocate among the firms the monopoly output that maximizes their joint profit. Similarly, if all plants of an n-plant firm have the cost function C(qi) = c qi, then it will not be possible to uniquely allocate the firm’s optimal output among the n plants. This paper identifies the nece...

Introduction: Ethnobutany, as a part of every region’s national capital, contains local beliefs and knowledge about plants and their characteristics being the result of centuries of trial and error in the natural environment. Though, it is unwritten and exposed to degeneration. Purpose: The purpose of this study was to acquire and document the culture of traditional use of Zebarkhan rangeland ...
