This research was conducted to evaluate the trend of cadmium accumulation in wheat tissue and cultivated soil affected conventional cropping systems and different growth stage via split plot experiment based on randomized complete block design with three replications during 2014-2015 seasonal year. The main factor included two cropping systems (wheat-rice, fallow-wheat) and growth stage at thre...

the impact of climate change in the next few decades will increase risks of wheat production under dryland conditions. therefore, it is important to find cultivars that are tolerant to these conditions and can provide reasonable yield under future climates. radiation use efficiency (rue) is the key factor determining the crop yield and is related to crop biomass and leaf area index (lai). t...

Background: Forests have a huge potential to mitigate global warming through CO2 accumulation in their living biomass. Thus, understanding the functioning of these ecosystems is crucial for revealing factors that drive biomass accumulation. Functional diversity helps us understand ecosystem services, including Within this context, work aimed investigate role functional woody vegetation Cerradão...

We report a case study of natural variations and correlations of some photosynthetic parameters, green biomass and grain yield in Cappelle Desprez and Plainsman V winter wheat (Triticum aestivum L.) cultivars, which are classified as being drought sensitive and tolerant, respectively. We monitored biomass accumulation from secondary leaves in the vegetative phase and grain yield from flag leave...

abstract salinity is one of the major abiotic challenges influencing plant productivity worldwide. to examine the response of two alfalfa cultivars (bami and hamedani) to six levels of water salinity (0, 25, 50, 75, 100, 125 mm l-1 nacl), a glasshouse experiment was conducted at the college of agriculture, shiraz university, shiraz, iran in 2008. the results showed that in bami (which appeared...

Recovery of biodegradable plastics from activated sludge is a promising sustainable technology. In this study, polyhydroxybutyrate (PHB) – a biodegradable plastics material was produced by activated sludge performing enhanced biological phosphorus removal (EBPR) in batch experiments under anaerobic, aerobic and anaerobic/aerobic conditions. Under anaerobic conditions, the PHB content of 28.8% o...
