“…The highest seeds number per pod in genotype AGS 313 was probably due to the lowest reduction in pollen fertility due to waterlogging as reported by Omae et al (2005). Waterlogging induced reduction in seeds per pod was higher at later stage waterlogging as reported by Umaharan et al (1997) and Zhou and Lin (1995).…”

“…Few studies have been conducted on different growth stages of field-grown oilseed rape under varying soil moisture [4,10,11]. Detailed field experiments have been predominantly directed toward analyzing the impacts of soil water content variability on physiological parameters and fruit yield [8,12,13].…”

Abstract:Oilseed rape (Brassica napus L.) is one of the three most important oil crops in China, and is regarded as a drought-tolerant oilseed crop. However, it is commonly sensitive to waterlogging, which usually refers to an adverse environment that limits crop development. Moreover, crop growth and soil irrigation can be monitored at a regional level using remote sensing data. High spatial resolution optical satellite sensors are very useful to capture and resist unfavorable field conditions at the sub-field scale. In this study, four different optical sensors, i.e., Pleiades-1A, Worldview-2, Worldview-3, and SPOT-6, were used to estimate the dry above-ground biomass (AGB) of oilseed rape and track the seasonal growth dynamics. In addition, three different soil water content field experiments were carried out at different oilseed rape growth stages from November 2014 to May 2015 in Northern Zhejiang province, China. As a significant indicator of crop productivity, AGB was measured during the seasonal growth stages of the oilseed rape at the experimental plots. Several representative vegetation indices (VIs) obtained from multiple satellite sensors were compared with the simultaneously-collected oilseed rape AGB. Results showed that the estimation model using the normalized difference vegetation index (NDVI) with a power regression model performed best through the seasonal growth dynamics, with the highest coefficient of determination (R 2 = 0.77), the smallest root mean square error (RMSE = 104.64 g/m 2 ), and the relative RMSE (rRMSE = 21%). It is concluded that the use of selected VIs and high spatial multiple satellite data can significantly estimate AGB during the winter oilseed rape growth stages, and can be applied to map the variability of winter oilseed rape at the sub-field level under different waterlogging conditions, which is very promising in the application of agricultural irrigation and precision agriculture.

“…En plantas de canola durante un periodo de inundación prolongada se forman raíces laterales pequeñas, carnosas y porosas, con alto contenido de aerénquima (Zhou y Lin 1995). En trébol blanco (Trifolium repens), Huber et al (2009) encontraron que bajo condiciones de inundación la porosidad de la raíz incrementa 60% en comparación con condiciones de buen drenaje.…”

A review Corte transversal de raíz nodal de Brachiaria humidicola a 21 días de inundación. Foto: J.A. Cardoso A. RESUMENLa inundación tiene un efecto negativo sobre la mayoría de plantas terrestres debido a que reduce su crecimiento e induce la senescencia. La deficiencia de oxígeno, efecto principal de la inundación, cambia el metabolismo de la planta induciendo la vía anaeróbica o fermentativa como mecanismo alterno, aunque poco eficiente para la producción de energía. Igualmente el déficit de oxígeno aumenta la producción de especies reactivas de oxígeno (ROS), tanto en la mitocondria como en el cloroplasto. Como respuesta al incremento de ROS hay un aumento en el sistema de defensa antioxidante de la planta, el cual es considerado, junto con la inducción de la vía fermentativa, como una respuesta a corto plazo. Cuando la planta está sometida a largos periodos de inundación se presentan, adicionalmente, cambios morfológicos, como la formación de aerén-quima, los cuales son considerados respuestas a largo plazo. En este artículo se revisan las respuestas, tanto a corto como a largo plazo, de las plantas a la condición de estrés hídrico por inundación.Palabras clave adicionales: respiración anaeróbica, defensa antioxidante, aerénquima, estrés abiótico. ABSTRACTFlooding has a negative effect on the majority of terrestrial plants due to a reduction of growth and the resulting senescence. Oxygen deficiency, the main effect of flooding, can change plant metabolism, inducing the alternative anaerobic pathway, an inefficient mechanism for energy production. Equally, the oxygen deficit increases the production of reactive oxygen species (ROS) both in chloroplasts and mitochondria. In response to increasing ROS, plants see a rise in their antioxidant defense system, which is considered, along with the fermentation pathway, a short-term response. When plants are submitted to long periods of flooding, they present morphological changes, such as aerenchyma formation, which is considered a longterm response. In this article, we review the short and long term responses of plants to water stress caused by flooding.
