Segmentation of sandplain lupin weeds from morphologically similar narrow-leafed lupins in the field
Researchers successfully trained a segmentation model to detect sandplain lupins and differentiate them from narrow-leafed lupins under field conditions.
A potential role for endogenous microflora in dormancy release, cytokinin metabolism and the response to fluridone in Lolium rigidum seeds
Lolium rigidum (annual ryegrass) is a widespread annual crop weed that has evolved high levels of resistance to selective herbicides. Anecdotal evidence suggests that intensive cropping also leads to higher seed dormancy in L. rigidum. This was quantified by measuring dormancy levels in L. rigidum populations collected from paired sites (one with nil to low cropping intensity, the other intensively cropped) located throughout the Western Australian grain belt.
Towards large-scale prediction of lolium rigidum I. Can climate be used to predict dormancy parameters?
Lolium rigidum (annual or rigid ryegrass) is a widespread annual weed in cropping systems of southern Australia. Seeds exhibit dormancy at dispersal and require a period of dry after-ripening to release dormancy, before germination and emergence can occur.
Towards large-scale prediction of Lolium rigidum emeregence II. correlation between dormancy and herbicide resistance levels suggest an impact of cropping systems
This study investigated a possible link between seed dormancy and herbicide resistance status of Lolium rigidum (annual or rigid ryegrass). Mature seeds were collected from 406 populations across the 14-million hectare grain belt of southern Western Australia.
Intensive cropping systems select for greater seed dormancy and increased herbicide resistance levels in Lolium rigidum (annual ryegrass)
