laboratory studies were conducted to compare the relative fitness of clodinafop-propargyl herbicide resistant lolium rigidum accessions with their clodinafop-propargyl susceptible counterparts in 2014. factors evaluated were lolium populations at constant salinity stress (0, 5, 10, 15, 20 and 25 ds cm2) and water stress (0, -3, -6, -9, -12 and -15 bar). the maximum germination in salinity stres...
Abstract In this investigation, which took place during the winter agricultural season of 2021-2022 in one fields located Al-Hindiya District Holy Karbala Governorate, purpose was to investigate effect various combinations herbicides on development and yield characteristics wheat as well a few weeds belonging genus Lolium. The experiment conducted out using randomized complete block design with...
The behavior and performance of the Russian wheat aphid, Diuraphis no&r (Mordvilko), on fungal endophyte-infected and endophyte-free perennial ryegrass, Lolium perenne L., was investigated in the laboratory and field. Aphids did not select endophytefree over endophyte-infected leaf sheaths and stem segments in petri dish preference tests. Similarly, the probing behavior of D. noxia on endophyte...
When subjected to shade, plants undergo rapid shoot elongation, which often makes them more prone to disease and mechanical damage. Shade-tolerant plants can be difficult to breed; however, they offer a substantial benefit over other varieties in low-light areas. Although perennial ryegrass (Lolium perenne L.) is a popular species of turf grasses because of their good appearance and fast establ...
Vernalization is a key requirement for the induction of flowering in perennial ryegrass (Lolium perenne L.). The transcriptome of two genotypes with contrasting vernalization requirement was studied during primary (vernalization and short day conditions) and secondary induction (higher temperature and long day conditions) using an RNA-Seq approach. This revealed transcripts with expression prof...
Perennial ryegrass (S23), timothy (S48), white clover (S100) and red clover (Hungaropoly), grown in culture solutions containing 0.2 x 5.0 x M-potassium iodide, showed relatively small differences in iodine uptake. The lowest uptake occurred with timothy, the species that also produced the lowest yields of dry matter. Red clover had the lowest concentration of iodine in the shoots on all treatm...
Some effects of l&m endophyte (Acremonium lolioe) on sheep production were evaluated using pure swards of h igh (SO%>) and low (< 5%) endophyte Nui and Ar ik i ryegrass. The proportion of infected t i l lers in high endophyte treatments increased by 19% in 15 months. Ryegrass staggers occurred on both high endophyte ryegrasses being sl ight ly worse on Nui . The peak ryegrass staggers outbreak ...
Thirty-eight Angus-cross beef cows were used to evaluate differences in DMI, residual feed intake (RFI), and endocrine markers on the basis of cow size and RFI ranking during 2 stages of production. Cows housed in individual pens (2.2 × 9.1 m) were fed, over a 70-d feeding period, 30% Bermuda grass hay and 70% ryegrass baleage diet during lactation (LACT) and a 100% ryegrass hay diet during pos...
