This research investigated the effects of super absorbentpolymers on root characteristics of Avena fatua under two soil textures and three irrigation regimes. The study was arranged according to a factorial experiment based on a completely randomized design with three replications. Hydrogel compositions included three types of super absorbents (Aquasorb, Boloorab A and Stockosorb) with two leve...
Allelopathic effects of aqueous extract of rhizomes of Cynodon dactylon L. were studied on seed germination and seedling growth of three legume crops (Phaseolus vulgaris L., Pisum sativum L., and Vicia faba L.), three Labiatae species (Thymus vulgaris L., Melissa officinalis L., and Mentha spicata L.), and two species of Poaceae (Avena fatua L., Sorghum halepense L.). Seed germination of all L...
Weeds are a major impediment to crop and pasture production profitability in Australian farming systems, knowledge of their occurrence is vital devising weed management solutions. This study examined the relationships between species from observations made during surveys randomly selected fields grain and/or production. Between 2013 2017, 996 across New South Wales (NSW) were surveyed record de...
A multivariate statistical analysis was performed on morphological characters of sixty-one populations of Avena eriantha Dur. A. clauda Dur., A. barbata Pott ex Link., A. wiestii Steud., A. fatua L., A. sterilis ssp. ludoviciana L. and A. sativa L. Factor analysis revealed that intraspecific morphological variations are due to quantitative characters. Interspecific as well as intersectional rel...
Present study was conducted to explore the herbicidal effect of volatile essential oil of Mentha longifolia (L.) L. and Chenopodium ambrosioides L. against Avena fatua L. weed. A significant effect of essential oil was observed on early seedling growth, chlorophyll content and cellular respiration over a concentration range of 0.01 – 0.25 mg/ml as compared to control ones. More inhibition was o...
Dormant seeds of Avena fatua, which do not germinate when allowed to imbibe water, have a respiration rate only about 20% less than that of imbibed nondormant (after-ripened) seeds in the period before actual germination and are capable of synthesizing protein at a rate comparable to that of the nondormant seeds. An increase of protein synthesis is observed in nondormant seeds at the beginning ...
UNLABELLED It is well known that rhizosphere microbiomes differ from those of surrounding soil, and yet we know little about how these root-associated microbial communities change through the growing season and between seasons. We analyzed the response of soil bacteria to roots of the common annual grass Avena fatua over two growing seasons using high-throughput sequencing of 16S rRNA genes. Ov...
