A major contributor to degradation on rangelands in the western United States is the expansion of undesirable annual weeds following wildfire or other disturbance. The Simultaneous Heat and Water (SHAW) model was applied to three soil types (loamy sand, sandy loam, and silt loam) to simulate near-surface soil temperature and water for predicting potential seed germination in post-wildfire reveg...

This study aims to determine some morphological characteristics of two-year-old common hornbeam (Carpinus betulus L.) and oriental orientalis Mill.) seedling the quality classes seedlings according Turkish Standards Institute’s (TSI) standards sturdiness quotient values. As a material, seedlings, grown from seed obtained three different altitudes as lower (0-400 m), mid (400-800 m) upper (800-1...

This work highlights the ability of various cyanobacterial extracts from Anabaena spp., Tolypothrix Nostoc or Trichormus, among others genera, to control incidence damping-off caused by Pythium ultimum in cucumber seedlings. Protocols applied aimed at preliminary characterization collection were very useful for predicting their phytotoxic, phytostimulating and biopesticidal capacity. First, phy...

The rare earth element (REE) cerium (Ce) can act as a biostimulant in diverse crop plants. effects of 0, 5, 10, and 15 µM Ce (supplied CeCl3 7H2O) on seed germination the initial growth tomato (Solanum lycopersicum L.) cv. Vengador were evaluated. After 12 h imbibition, weight seeds treated with was 37.5% greater than that observed control. index 5 100% (101.93%), though when applying 10 this 1...

We describe and illustrate a new needle nematode, Longidorus americanum n. sp., associated with patches of severely stunted and chlorotic loblolly pine, (Pinus taeda L.) seedlings in seedbeds at the Flint River Nursery (Byromville, GA). It is characterized by having females with a body length of 5.4-9.0 mm; lip region slightly swollen, anteriorly flattened, giving the anterior end a truncate ap...
