green roofs are a part of efforts to make the cities more sustainable and it is one of the modern solutions for urban problems. the physical development of cities led to loss of the natural environment. therefore, the development of green spaces plays an important role in human life. in order to evaluate the effect of some culture media on yield of “oenothera speciosa rosea” in green roof situa...

Weedy rice is a conspecific form of cultivated rice (Oryza sativa L.) that infests rice fields and results in severe crop losses. Weed strains in different world regions appear to have originated multiple times from different domesticated and/or wild rice progenitors. In the case of Malaysian weedy rice, a multiple-origin model has been proposed based on neutral markers and analyses of domestic...

The effects of black rice powder on the quality of sausage were investigated. Samples were prepared with 0% (control), 1%, 3%, and 5% black rice powder. With increasing black rice powder content, the moisture and ash content of sausage increased, while protein content was significantly less than that observed for the control (p<0.05). The fat content in samples containing 5% black rice powder w...

Lignin content and composition are two important agronomic traits for the utilization of agricultural residues. Rice (Oryza sativa) gold hull and internode phenotype is a classical morphological marker trait that has long been applied to breeding and genetics study. In this study, we have cloned the GOLD HULL AND INTERNODE2 (GH2) gene in rice using a map-based cloning approach. The result shows...

Effects of rice husk ash (RHA) on the strength and temperature resistance of concrete were investigated. Different amounts of cement in concrete were replaced by RHA and fly ash (FA), used as mineral admixtures, under the condition of a constant binder content. The compressive strength and temperature resistance were tested at different temperatures. The results show that mixing concrete with t...

Plastic mulch increased minimum temperature of soil, accelerated plant height,early growth, early yield, and bring satisfactory weed control without anyapplication of herbicides. This experiment was laid out on three-factorialRandomized Complete Block Design with three replications during 2008-2010 atthe National Rice Research Institute, Rasht, Iran using three kinds of mulches(Transparent and ...
