Abstract: The objective of this work was to evaluate the potential solute translocation among stems wheat (Triticum aestivum), by application systemic herbicides clethodim and glyphosate. experiments were carried out in greenhouse conditions, using cultivars with contrasting for tillering, during winter 2017 2018 Southern Brazil. Clethodim applied on isolated stems, solutes from first three til...

The influence of plant roots and the associated rhizosphere activities on decomposition of soil organic matter (SOM), the rhizosphere priming effect, has emerged as a crucial mechanism regulating global carbon (C) and nitrogen (N) cycles. However, the role of root morphology in controlling the rhizosphere priming effect remains largely unknown. To investigate the link between root hairs, a crit...

In dryland Mediterranean semi-arid areas, the use of slurries and no-till are encouraged to reduce costs. This paper evaluates effect such practices in terms morphological changes topsoil porosity. The experiment had seven fertilization strategies (five them including pig applied at cereal sowing or tillering) combined with tillage by disc-harrowing sowing. Soil was classified as a Typic Xerofl...

Introduction The red:far-red ratio (R:FR) is a key variable in many biological processes from basic ones such as the response of phytochrome to more integrated ones, such as tillering or weed competition. Accurate estimation of the red:far-red ratio of plant organs in field condition is an important issue to be able to integrate the increasing knowledge on phytochrome-driven processes from cell...

to study the effects of urea foliar spray at different plant growth stages on grain yield and protein percentage of two dryland wheat varieties of sardari and azar 2, an experiment was conducted in east mangor agricultural station of mahabad in 2007– 2008. the experiment design was split plot based on randomized complete block design with three replications. treatments were 50 gr×10 m-2 n as ur...

the nitrogen (n) nutrition, crop yield, and responses of wheat to arbuscular mycorrhizal fungi (amf) were tested in an experimental field under free-air ozone concentration [o3] enrichment (face) conditions. the experiment included three treatments: ambient [o3] (ambient), elevated [o3] (face, targeted at ambient [o3]×1.5), and elevated [o3] inoculated with an amf consortium consisting of sever...
