Switchgrass (Panicum virgatum L.) is typically slow and difficult to establish. Field experiments evaluated switchgrass establishment and the response of warm-season grass weeds (large crabgrass [Digitaria sanguinalis (L.) Scop.], broadleaf signalgrass [Urochloa platyphylla (Munro ex C. Wright) r.D. Webster], Johnsongrass [Sorghum halepense (L.) pers.], and Texas panicum [Urochloa texana (Buckl...

Maize redness (MR), induced by stolbur phytoplasma ('Candidatus Phytoplasma solani', subgroup 16SrXII-A), is characterized by midrib, leaf, and stalk reddening and abnormal ear development. MR has been reported from Serbia, Romania, and Bulgaria for 50 years, and recent epiphytotics reduced yields by 40 to 90% in South Banat District, Serbia. Potential vectors including leafhoppers and planthop...

the allelopathic effect of weeds frequently inhibited the germination and seedling growth of crops. johnsongrass (sorghum halepens) is known to contain water-soluble substances that are allelopathic. to identify the allelopathic effect of johnsongrass, the effect of different aqueous extracts (0, 5, 10, 20, 30, 40 and 50 g l-1) obtained from roots and leaves of johnsongrass on the seed germinat...

The infrageneric phylogeny and temporal divergence of Sorghum were explored in the present study. Sequence data of two low-copy nuclear (LCN) genes, phosphoenolpyruvate carboxylase 4 (Pepc4) and granule-bound starch synthase I (GBSSI), from 79 accessions of Sorghum plus Cleistachne sorghoides together with those from outgroups were used for maximum likelihood (ML) and Bayesian inference (BI) an...

Biopulping, the treatment of wood chips by white rot fungi and subsequent chip refining is envisioned as a method for saving energy and making a stronger paper product. The present study aims to find suitability of two fungal isolates Phellinus pectinatus and Daedaleopsis confragosa for the process of biopulping and the characteristion of the biologically pretreated raw materials for biopulping...

UNLABELLED PREMISE OF THE STUDY Invasive plants can alter soil microbial communities and profoundly alter ecosystem processes. In the invasive grass Sorghum halepense, these disruptions are consequences of rhizome-associated bacterial endophytes. We describe the effects of N2-fixing bacterial strains from S. halepense (Rout and Chrzanowski, 2009) on plant growth and show that bacteria intera...

Abstract Weed control in corn is a major challenge due to increasing problems with highly dominant weed species and herbicide resistance evolution. Common lambsquarters johnsongrass constitute up 80% 90% of the population many spring crops, such as soybean [ Glycine max (L.) Merr.], sunflower ( Helianthus annuus L.), corn, Serbia. Currently, acetolactate synthase–inhibiting herbicides, systemic...
