Evaluation of genetic effect on physicochemical properties changes of Wx near isogenic lines of Y58S in rice


There was exponential and positive significant correlation between biomass an N uptake and leaf area index of ratoon rice and normalised difference vegetation index (NDVl) after heading of main rice. These results indicated that NDVI values after heading of main rice can better reflect changes of physiological indexes in ratoon rice. However, these regression models need to be further verified it before it would be applied in ratoon rice.
