The wall-associated kinase GWN1 controls grain weight and grain number in rice

Theoretical and Applied Genetics
Grain size is a crucial agronomic trait that determines grain weight and final yield. Although several genes have been reported to regulate grain size in rice (Oryza sativa), the function of Wall-Associated Kinase family genes affecting grain size is still largely unknown.

Improving Document Classification Using Fine-Grained Weights

2015
In this paper document classification methods using multinomial naive Bayes are improved in a number of ways. We use the value weighting method, a new fine-grained weighting method, to calculate the weights of the feature values. Our experiments show that the proposed approach outperforms other state-of-the-art methods.

Prediction of grain weight, brown rice weight and amylose content in single rice grains using near-infrared reflectance spectroscopy

Field Crops Research, 2004
Abstract The potential of near-infrared reflectance spectroscopy (NIRS) for simultaneous analysis of grain weight (mg), brown rice weight (mg) and milled rice amylose content (AC, %) in single rice grains was studied. Calibration equations were developed using 474 single grain samples, scanned as both rice grain and brown rice.

Weight Determining of Factors Influencing Grain Output Based on Entropy Weight Method

2012
This article selects 8 main factors (the number of rural employees, total power of agricultural machinery, effective irrigation area of crops, growing area of grain crops, fertilizer consumption, electricity consumption in rural areas, area affected and area covered) as the factors influencing grain output, and offers the method of determining weight ...

Effect of vernalization on grain fill duration and grain weight in spring wheat

2011
Vernalization response genes are known to contribute indirectly to grain yield by influencing flowering time, number of tillers and spikelets in sensitive wheat genotypes. There has been no report of the effect of vernalization on grain fill duration and grain weight in wheat.
