The polarimetric behaviour of rice fields at different phenological stages has been analysed by using time series of TerraSAR-X images. These are X-band copolar dual-pol images available for the whole growth cycle. As plants grow, changes in their morphology produce clear signatures in various polarimetric observables. Based on this sensitivity to phenology, a physically based retrieval approac...
Abstract. Information on forage quality in phenological stage could help range managers to choose suitable grazing method to achieve higher animal performance without detriment to vegetation. Vetiver grass (Vetiveria zizanioides) is a non-native perennial grass that was introduced to the Iran in 2008. This plant is a multi use species that could be considered from different viewpoints. Thus, it...

Organisms' life cycles consist of hierarchical stages, from a single phenological stage (for example, flowering within a season), to vegetative and reproductive phases, to the total lifespan of the individual. Yet phenological events are typically studied in isolation, limiting our understanding of life history responses to climate change. Here, we reciprocally transfer plant communities along ...
Regulated deficit irrigation (RDI) is commonly used during different phenological stages of fruit growth and development in almond trees to reduce the amount of irrigation water applied without or with only very small reductions in yield. Therefore, to study the effects of deficit and cutoff irrigation during different phenological stages of fruit growth and development in almond cv. “Mamaei” p...
in order to estimate the relationship between forage quality and preference value of plant species for raini goats(capra aegagrus hircus), a field study was carried out on raini goats’ grazing behavior in some desert habitats.crude protein (as the most important factor affecting forage quality) of all plant species was measured at twophenological stages (spring and summer, 2010) in the dry rang...
The growth and production of sweet sorghum [Sorghum bicolor (L.) Moench] crops under semi-arid conditions in the Mediterranean environment of southern Italy are constrained by water stress. The effects of temporary water stress on growth and productivity of sweet sorghum were studied during three seasons at Rutigliano (Bari, Italy). The aim of this research was to evaluate the sensitivity of ph...
Spartina alterniflora has widely invaded the saltmarshes of the Yangtze River Estuary and brought negative effects to the ecosystem. Remote sensing technique has recently been used to monitor its distribution, but the similar morphology and canopy structure among S. alterniflora and its neighbor species make it difficult even with high-resolution images. Nevertheless, these species have diverge...
five common range forage including agropyron intermedium, bromustomentellus, hordeum bulbosum, cousinia bakhtiarica and scariolla orientalis, weresampled during three phenological stages, from controlled rangeland stations over fivelocations in chaharmahal and bakhtiari province, iran. all samples were chemicallyanalyzed for crude protein (cp%), in vitro dry matter digestibility (dmd), organicm...
