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 کاملHormonal Regulation of alpha-Amylase Gene Transcription in Wild Oat (Avena fatua L.) Aleurone Protoplasts.
The time of appearance and relative amounts of alpha-amylase mRNA in wild oat (Avena fatua L.) aleurone protoplasts incubated with 1 micromolar gibberellin A(4) (GA(4)) were closely correlated with the amounts of alpha-amylase enzyme secreted by the protoplasts. In the absence of GA(4), or when protoplasts were incubated with 25 micromolar abscisic acid (ABA) together with 1 micromolar GA(4) no...

15 صفحه اولPrediction of emergence of Flixweed (Descurainia sophia) and Wild Oat (Avena fatua) using thermal time models in Winter Rapeseed (Brassica napus)
A thermal time (TT) model was developed to simulate field emergence of two weed species (flixweed and wild oat) in winter rapeseed. Practical predictive weed emergence models can provide information about timing of weed emergence. Non-linear regression models are usually able to accurately predict field emergence under specific environmental conditions. In the present study, cumulative seedling...
