Selecting plants adapted to the climatic and soil conditions of specific locations is essential for environmental protection and economic sustainability of agricultural and pastoral systems. This is particularly true for countries like China with a diversity of climates and soils and intended uses. Currently, proper species selection is difficult due to the(More)
Quantitative study of root morphological characteristics of plants is helpful for understanding the relationships between their morphology and function. However, few studies and little detailed and accurate information of root characteristics were reported in fine-rooted plants like rice (Oryza sativa L.). The aims of this study were to quantitatively(More)
The objectives of this paper were to examine cultivar differences of aboveground rice plant morphology and structure at the early tillering stage, and analyze its potential correlations with yield. The 4 rice cultivars, Liangyou108 (hybrid long-grain rice, V1), 86You8 (hybrid round-grain rice, V2), Nanjing43 (round-grain rice, V3), and Yangtao6 (long-grain(More)
A major objective of the Sun Grant GIS component is to gain an understanding of the spatial distribution of current and potential biofuel/bio-energy feedstock resources across the country. To this end, the Sun Grant Western Region GIS Center (PRISM Climate Group) at Oregon State University has developed, and is applying, an environmental modeling approach(More)
