Defense Enzyme Responses in Dormant Wild Oat and Wheat Caryopses Challenged with a Seed Decay Pathogen
Seeds have well-established passive physical and chemical defense mechanisms that protect their food reserves from decay-inducing organisms and herbivores. However, there are few studies evaluating potential biochemical defenses of dormant seeds against pathogens. Caryopsis decay by the pathogenic Fusarium avenaceum strain F.a.1 was relatively rapid in wild oat (Avena fatua L.) isoline "M73," w...
متن کاملبررسی ویژگی‌های برگ و نسبت ریشه به ساقه در تداخل اندام‌های زیرزمینی و هوایی گندم زراعی ( Triticum aestivum ) و تراکم‌‌های مختلف یولاف وحشی ( Avena fatua )
A pot experiment was designed to investigate the effects of full, above and below ground interactions of wheat with wild oat on leaf characteristics and root to shoot ratio. This experiment was conducted as a factorial based on randomized complete design with four replications. The treatments included four interference levels (above ground, below ground, above and below ground and check wheat a...
متن کاملDosimetric comparison of conventional and field-in-field techniques in early stage breast cancer radiotherapy
Introduction: Breast conserving surgery followed by adjuvant radiotherapy (RT) of the whole breast is accepted as the treatment of choice in early stage breast cancer. Due to breast irregularities, it is difficult to access homogenous dose distribution with conventional techniques. Currently, it is possible to use varied breast irradiation techniques, such as field- in-field (F...
متن کاملUsing Wild Oat Growth and Development to Develop a Predictive Model for Spring Wheat Growers and Consultants
Introduction: Wild oat has become an invasive and economically important weedy species in most cereal growing areas of the world, including the Red River Valley of Minnesota and North Dakota. Approximately 79% of the wheat and 72% of barley acres seeded in northwestern Minnesota are infested with wild oat. In the past, wild oat has been effectively controlled with herbicides, and as a result li...
