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 کاملGenetic Studies of Two QTLs for Rice Stripe Resistance Identified in Japanese Upland Rice Line, Kanto 72
Quantitative trait locus (QTL) analysis was performed to identify the chromosomal region controlling rice stripe virus (RSV) resistance in Japanese upland rice, Kanto 72. As a result, two QTLs were detected on chromosomes 2 and 11. Using near-isogenic lines possessing a single QTL (QTL-NILs) on chromosomes 2 and 11, the effects of two QTLs were evaluated. The target QTL regions were introduced ...
متن کاملPlant Root System Analysis from MRI Images
We present a novel method for deriving a structural model of a plant root system from 3D Magnetic Resonance Imaging (MRI) data of soil grown plants and use it for plant root system analysis. The structural model allows calculation of physiologically relevant parameters. Roughly speaking, MRI images show local water content of the investigated sample. The small, local amounts of water in roots r...
متن کاملRoot System Regulation of Whole Plant Growth1
New evidence confirms earlier postulates that root signals to shoots, including abscisic acid, nitrate flux, and cytokinins, modify whole plant growth processes including leaf expansion, stomatal behavior, and biosynthesis of photosynthetic enzymes. Root signals are thought to reflect soil water, nutrient, and mechanical attributes, as sensed by roots. Meristematic activities in root tips initi...
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...
