Plant growth and phenolic compounds in the rhizosphere soil of wild oat (Avena fatua L.)
The objectives of this study were to determine the pattern of dry matter (DM) accumulation and the evolution of phenolic compounds in the rhizosphere soil from tillering to the ripe seed stages of wild oat (Avena fatua L.), a widespread annual grassy weed. Plants were grown under controlled conditions and harvested 13 times during the growing season. At each harvest, shoot and root DM and pheno...
متن کاملCharacterisation of Avena fatua populations with resistance to multiple herbicides
Avena fatua (wild oat) populations with resistance (R) to one or more herbicides have been described in numerous cropping systems worldwide. We previously reported that the R3 and R4 wild oat populations from Montana, USA, were resistant to four herbicides representing three different modes of action: tralkoxydim [acetyl-CoA carboxylase (ACCase] inhibitor), imazamethabenz and flucarbazone [acet...
متن کاملEarly Actions of Gibberellic Acid on the Embryo and on the Endosperm of Avena fatua Seeds.
Gibberellic acid at 0.1 mum stimulates amylase synthesis in dormant Avena fatua seeds without inducing germination; at 0.5 mm it enhances biosynthesis of proteins and RNA in both the embryo and the endosperm and utilization of the endosperm sugars by the embryo. These events occur in early hours (0-14th hour) and prior to germination, which begins 24 hours after gibberellic acid application. Th...
متن کاملRespiration and Protein Synthesis in Dormant and After-ripened Seeds of Avena fatua.
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 ...
متن کاملComparative Phytotoxic Effect of the Essential Oil of Chenopodium Ambrosioides and Mentha Longifolia on Avena Fatua
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...
