this study was conducted to determine the effects of the combined use of rain shelters (rs) and deficit irrigation (di) on tomato yield and quality characteristics. two experiments with different treatments were conducted in the southern china during the growing season in 2011 and 2012. the crops were irrigated to field capacity once average soil water content at the 0-60 cm layer in the treatm...
Understanding the effects of climate on vital rates (e.g., survival, development, reproduction) and dynamics natural populations is a long-standing quest in ecology, with ever-increasing relevance face change. However, linking drivers to demographic processes requires identifying appropriate time windows during which influences rates. Researchers often do not have access long-term data required...
Vegetation phenology has been used in studies as an indicator of an ecosystem’s responses to climate change. Satellite remote sensing techniques can capture changes in vegetation greenness, which can be used to estimate vegetation phenology. In this study, a long-term vegetation phenology study of the Greater Khingan Mountain area in Northeastern China was performed by using the Global Inventor...
The development of models to predict yield potential and quality of a Miscanthus crop must consider climatic limitations and the duration of growing season. As a biomass crop, yield and quality are impacted by the timing of plant developmental transitions such as flowering and senescence. Growth models are available for the commercially grown clone Miscanthus x giganteus (Mxg), but breeding pro...
