The development of transgenic soybean has produced numerous economic benefits; however the potential impact of root exudates upon soil ecological systems and rhizospheric soil microbial diversity has also received intensive attention. In the present study, the influence of saline-alkali tolerant transgenic soybean of betaine aldehyde dehydrogenase on bacterial community structure and soil phosp...
Poa genus has a high value for grazing and forage conservation concerning thelivestock. In order to study the impacts of cold temperature and Growing Degree Days(GDD) on seedling morphological trait and phonological development of two speciesinvolving Poa pratensis and Poa trivialis, this research was conducted in laboratory andgreenhouse and outdoor of Research Institute of Forest and Rangelan...
in order to investigate the impact of foliar zn application in reducing the negative effects of water stress on bean growth and yield, a field experiment was carried out in the research field of ilam university in 2011. the experiment was arranged in split factorial based on a randomized complete block design with three replications. the experimental factors were water stress including water wi...
oregano (origanum vulgare l.), a native plant from iran, belongs to lamiaceae family. this species is traditionally utilized as sedative, diuretic, sweater and antiseptic, it is also used to treat of gastrointestinal diseases and constipation. origanum species are widely used in spice industry. in this study, the essential oil of the aerial parts of a subspecies from this plant namely origanum ...
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 ...
What is the flowering transition? It marks the end of vegetative growth and the beginning of reproductive development in flowering plants. The physiological changes that cause it are referred to as floral induction. What is SAM? The shoot apical meristem — a group of undifferentiated progenitor cells that occupies the tip of the stem. It gives rise to both vegetative organs (leaves) and reprodu...
In order to evaluate the intensity and stage of drought stress on agronomic characteristics and drought tolerance of common bean (Phaseolus vulgaris L.), a split plot factorial experiment was conducted in a randomized complete block design with three replications at Shahrekord University in 2013 and 2014. Drought stress treatments and levels of irrigation regimes were considered at vegetative g...
Agro-meteorological aspects of wheat (Triticum aestivum.L.) at New Delhi have been studied in this paper. A data set six years during the crop growing season between 1985 to 1993 has utilized. The growth period divided into important stages i.e., crown root initiation, tillering, elongation, flowering, grain development and maturity. Water requirement various its growth, water use efficiency, c...
partitioning of photoassimilates between the sinks is one of the most important physiological processes related to the yield of crops which are affected by drought stress. therefore, the effect of drought stress in flowering and grain filling stages, on the percentage partitioning of photoassimilates among different organs was studied in 14 rapeseed cultivars in a split plot experiment based on...
agricultural practices always need accurate information about occurrence of particular developmental stages. data from planting dates trials conducted over the kabotar-abad agricultural research station, isfahan during 2003-2009 were used to develop models for estimating developmental stages duration of sofea safflower variety. to model duration of each developmental stage, duration of each dev...
