TL;DR: In this paper, the authors used static scanning technology to collect images of a rice sample's fully expanded top three leaves and corresponding sheathes and extracted 32 spectral and shape characteristic parameters using an RGB mean value function and using the Regionprops function in MATLAB.

TL;DR: This study explores the relationship between CORONA texture—a surrogate for actual land cover type and complexity—with spectral vegetation indices and texture variables derived from Landsat MSS under the Spectral Variation Hypothesis (SVH) such as to reconstruct historical continuous land covertype and complexity.

TL;DR: The results indicate that the changing rates in dynamic characteristics, in particular the shape characteristics of the first incomplete leaf (FIL) and the characteristics ofThe 3rd leaf (leaf color and etiolation indices), expressed obvious distinctions among different nitrogen treatments.

TL;DR: According to the results, higher nutrient supply resulted in a faster leaf extension rate and a lower developing rate of chlorosis, and the influence of N deficiency on leaf growth was the greatest, followed by P deficiency and then K deficiency.

TL;DR: In this article , the authors found that low-temperature and anaerobic conditions are two major limiting factors in the germination of direct-seeded rice, and that low temperature is the key limiting factor for seed germination.
