High Performance Liquid Chromatography (HPLC), Steroidal Saponins, Avena sativa, Etioplasts Reversed phase high performance liquid chromatog­ raphy offers an efficient and rapid method for analysis of steroidal saponins. Crude extracts from primary leaves of Avena sativa and isolated etioplasts therefrom have been resolved into four saponins (avenacosides) using a wateracetonitrile gradient sys...

The challenges of grass-weed control in a mild Atlantic climate, added to by the use non-inversion tillage and limited herbicide options necessitated on-farm knowledge acquisition on grass weeds Ireland. We surveyed 103 farms from 2020 2021 which, 62 were plough-based 41 tillage. survey comprised questionnaire determine grower demographics, challenges, adoption integrated methods (IWM); grid-sq...

The chromosome set of Avena macrostachya Balansa ex Coss. et Durieu was analyzed using C-banding and fluorescence in situ hybridization with 5S and 18S-5.8S-26S rRNA gene probes, and the results were compared with the C-genome diploid Avena L. species. The location of major nucleolar organizer regions and 5S rDNA sites on different chromosomes confirmed the affiliation of A. macrostachya with t...

Myristica fatua var. magnifica (Beddome) Sinclair belongs to the family Myristicaceae. It is a tree used as an important plant to cure various diseases. In the present study the Petroleum ether, Ethyl acetate and Methanolic extracts of Myristica fatua was evaluated for its toxicity, potential analgesic, depressant and in vitro and in vivo anti-inflammatory activity. The extracts at different co...

Weed emergence models and weed population models have shown to be important tools for decision making. However, there have been no attempts to integrate a weed emergence model with a population dynamics model to build an improved model with increased predictive capacity. In this paper, a method of integrating both types of model is presented and an application building a mathematical model base...
