Upland Rice and Allelopathy
Upland rice (Oryza sativa L.) is mainly grown in Asia, Africa and Latin America. Yield potential of upland rice is quite low and invariably this crop is subjected to many environmental stresses. Further, when upland rice is grown in monoculture for more than two to three years on the same land, allelopathy or autotoxicity is frequently reported. Allelopathy involves complex plant and plant chem...
متن کاملProtein profile of rice (Oryza sativa) seeds
Seeds are the most important plant storage organ and play a central role in the life cycle of plants. Since little is known about the protein composition of rice (Oryza sativa) seeds, in this work we used proteomic methods to obtain a reference map of rice seed proteins and identify important molecules. Overall, 480 reproducible protein spots were detected by two-dimensional electrophoresis on ...
متن کاملInterpreting Upland Rice Yield and Pratylenchus zeae Relationships: Correspondence Analyses.
Correspondence analyses were used to explore the relationships between yield and populations of Pratylenchus zeae in an upland rice field and in a greenhouse experiment. Initial soil (Pi) and final root (Pf) population densities of P. zeae, and yield (Y) of rice cv. UPL Ri5 were determined at 490 spots in the field. Very low Y was linked to very high Pf. Low Y was linked to medium or high Pi an...
متن کاملLocating Genes Controlling Allelopathic Effects against Barnyardgrass in Upland Rice
the environment” (Rice, 1984). Rice plants with an allelopathic effect on weeds can mean lower production To understand the genetic control of allelopathy in rice (Oryza costs because the need for herbicide application and/or sativa L.), quantitative trait loci (QTL) mapping was performed using a population of 142 recombinant inbred lines derived from a cross hand weeding is reduced. Thus, inco...
