Research paper thumbnail of Impact of ALS Herbicide-Resistant Perennial Ryegrass (Lolium perenne) Population on Growth Rate and Competitive Ability against Wheat

Agronomy

Three perennial ryegrass (Lolium perenne) populations (R1, R2, and R3) with suspected resistance ... more Three perennial ryegrass (Lolium perenne) populations (R1, R2, and R3) with suspected resistance (R) to acetolactate synthase (ALS) or acetyl-CoA carboxylase (ACCase) herbicides were collected from wheat (Triticum aestivum) fields in northwestern Greece to study the underlying mechanisms of resistance and their impact on growth rate and competitive ability against wheat. Preemergence and postemergence plant dose–response assays showed that the R1 population was cross-resistant to the ALS inhibitors chlorsulfuron, mesosulfuron + iodosulfuron, and pyroxsulam, but susceptible (S) to imazamox. However, all populations were susceptible to the ACCase inhibitors clodinafop-propargyl, clethodim, diclofop-methyl, and pinoxaden. The analysis of the ALS gene sequence revealed a substitution of Pro197 by His or Leu in the ALS enzyme in L. perenne, which is reported for the first time in this weed and indicates a potential mechanism of target site-mediated resistance. The R1 population grown in ...

This version will undergo additional copyediting, typesetting and review before it is published in its final form, but we are providing this version to give early visibility of the article. Please note that, during the production process, errors may be discovered which could affect the content, and all legal disclaimers that apply to the journal pertain.

Research paper thumbnail of Antibacterial Activity of Greek and Cypriot Honeys Against Staphylococcus aureus and Pseudomonas aeruginosa in Comparison to Manuka Honey

The minimum inhibitory concentration (MIC) was determined in broth using a spectrophotometric-based assay. The MIC of treated honeys with catalase or proteinase K was determined and compared with those of untreated honeys. All tested honeys demonstrated antibacterial activity against S. aureus on agar-well diffusion assay. MICs of tested honeys were determined as 3.125-25% (v/v), compared with manuka honey at 6.25% (v/v). Similarly, 21 of 31 tested honeys demonstrated antibacterial activity on agar-well diffusion assay against P. aeruginosa. Their MICs ranged from 6.25% to 25% (v/v) compared with 12.5% (v/v) for manuka honey. Antibacterial activity of tested honeys could be largely attributed to hydrogen peroxide formation and in some cases to unidentified proteinaceous compounds. In conclusion, Greek and Cypriot honeys demonstrated significant but variable antibacterial activity against P. aeruginosa and especially S. aureus. To the best of our knowledge this is the first study that has thoroughly examined the antibacterial activity of Greek and Cypriot honeys compared with manuka honey. The high antibacterial activity exerted by some tested honeys warrants further investigation.

Using the improved cultivar ‘Thrakiotiko’ and the galia type hybrid ‘Masada’ as scions, on the rootstock ‘Thrakiotiko-1’ significantly increased yield by 36% compared to...

Using the improved cultivar 'Thrakiotiko' and the galia type hybrid 'Masada' as scions, on the rootstock 'Thrakiotiko-1' significantly increased yield by 36% compared to the ungrafted control, whereas the performance of the same rootstock used for 'Masada' was similar to that of the other melon rootstocks and the control. In addition, 'Thrakiotiko-1' improved fruit quality in both grafted cultivars. 'Thrakiotiko-2' performed similarly to the commercial rootstocks, without differing significantly from the control.
