As plantas daninhas interferem nos gramados, prejudicando a sua formação, qualidade e estética. O carrapicho-beiço-de-boi (Desmodium incanum) e a zórnia (Zornia latifolia), quando não controlados, podem atingir níveis de infestação que chegam a dizimar o gramado.

Temporal and spatial expression of genes involved in DNA methylation during reproductive development of sexual and apomictic Eragrostis curvula [PDF]
Recent reports in model plant species have highlighted a role for DNA methylation pathways in the regulation of the somatic-to-reproductive transition in the ovule, suggesting that apomixis (asexual reproduction through seeds) likely relies on RdDM ...

Distinct phosphorus release from fresh and legacy biosolids‐amended sandy soils
Abstract Biosolids are commonly used as soil amendments; however, repeated application of biosolids results in phosphorus (P) accumulation, elevating environmental risks by increasing P loss through runoff and leaching. Predicting soil P loss after ceasing biosolids application remains challenging.

Selection of Brazilian native turfgrass accessions for establishment by sprigs
Researches with Brazilian native species of Axonopus and Paspalum genus have indicated their lawn-use. Thus, this research aimed to evaluate the use of sprigs, which are rhizomes and/or stolons fragments of plants without substrate and with reduced ...

Variation in foliar inorganic phosphorus concentrations in perennial ryegrass (Lolium perenne L.)
ABSTRACT Breeding ryegrass for reduced inorganic phosphorus (Pi) concentrations in leaf vacuoles could lower pasture P fertiliser requirements with economic and environmental benefits. We investigated foliar Pi% accumulation characteristics of a range of ryegrass cultivars and ecotypes in glasshouse experiments, and ryegrass cultivars from two field ...

Residual sexuality and its seasonal variation in natural apomictic Paspalum notatum accessions
Traditionally, tetraploid Paspalum notatum was considered an obligate or a facultative apomict according to cytoembryological analyses. The degree of facultativeness was usually determined by the relative amount of mature ovules bearing aposporous or ...
