A modified in situ technique for measuring heterotrophic nitrogen fixing (acetylene reducing) activity associated to rice is proposed. Ethylene evolution rates measured in opaque cylinders covering the stems of rice plants which have been cut 10 cm over the water level were found independent of the diurnal cycle. Cutting of the leaves resulted in decreased variation between plants and suppressi...
Defatted rice bran was treated with subcritical water between 120 and 240°C. The extraction temperature af fected the total carbohydrate and protein contents of the extracts. In the tested temperature range, the total carbohydrate and protein contents were the highest at 180°C and 210°C. The DPPH radical scavenging activity of the extracts increased with increasing extraction temperature up to ...
In order to increase gross harvest and productivity of rice, the development new varieties their timely use in production is great importance. The Federal Research Center Rice Agricultural “Donskoy” regularly develop more productive with improved resistance diseases other factors. Each variety forms a specific response various agro-ecological conditions, which affects productivity, main indicat...
Growth-regulating factor (GRF) interacting factors (GIFs) are involved in several developmental processes in Arabidopsis. We previously showed that upregulation of OsGIF1 expression improves rice grain size. However, whether OsGIF1 is involved in other developmental processes remains unclear. Here, we report pleiotropic effects of OsGIF1 on rice organ size regulation. Overexpression and functio...
Harnessing stem carbohydrate dynamics in grasses offers an opportunity to help meet future demands for plant-based food, fiber and fuel production, but requires a greater understanding of the genetic controls that govern the synthesis, interconversion and transport of such energy reserves. We map out a blueprint of the genetic architecture of rice (Oryza sativa) stem nonstructural carbohydrates...
ABSTRACT Rice is one of the main foods consumed by half world’s population. The rice crop requires plenty water, but upland cultivated in a non-flooded environment, although its productivity lower than that lowland rice. grains mostly consist starch, which synthesized from non-structural carbohydrates imported vegetative organs. long-term storage plays remarkable role maintaining supply photoas...
Tobacco stems contain 56.10% cellulose content, 15.11% lignin, 22.44% hemicellulose, and 44.61% total organic carbon, which can be used as a source of energy or fuel. This study aimed to utilize tobacco in briquette form alternative energy. The materials this were stem waste, rice husk, wood charcoal, coconut shell. treatments consisted T1 (100% stems), T2 (80% + 20% shell), T3 husk), T4 (33.33...
The expansion of rice cultivation in Paraguay observed the last five agricultural seasons, together with new technologies applied, has been accompanied by an increase presence diseases affecting leaf sheaths and stems. In view scarcity information country on some these diseases, this study was carried out to characterise stem rot. Samples symptomatic plants were collected from commercial lots l...
