Photosystem II fluorescence and growth in cabbage plants (Brassica oleracea var. capitata) grown under waterlogging stress

Abstract

Waterlogging stress is a limiting factor in the production of crops grown in localities with high rainfall frequency. Waterlogging causes a decrease in the availability of O2 in roots, which substantially affects the anatomy, morphology and metabolism of plants. Oxygen deficiency inhibits mitochondrial respiration, oxidation, and oxygenation processes, causing severe affection of plant metabolism. A test in greenhouse conditions was carried out in Tunja, Colombia, in order to evaluate the effect of waterlogging on the growth of cabbage plants (Brassica oleracea var. capitata). Some plants were waterlogged for 25 days and their physiological response was compared with plants maintained at field capacity. As consequence of waterlogging, leaf area, total dry weight, chlorophyll content, leaf area ratio, absolute growth rate and relative growth rate were reduced. In addition, necrotic plants exhibited a high percentage of necrosis in the leaves. As for the variables related to chlorophyll fluorescence, there was a decrease of 17,9, 50,0 and 36,0% in the Fv/Fm values, ΦPSII and qP, respectively. All of these results indicate low tolerance of cabbage plants to waterlogging.

Physiological, Biochemical and Chlorophyll Fluorescence Parameters of Physalis Peruviana L. Seedlings Exposed to Different Short-Term Waterlogging Periods and Fusarium Wilt Infection

“…Ren et al [23] found a reduction of 16% in the F v /F m and Y (II) values in two maize (Zea mays L.) hybrids under short waterlogging periods (6 d). Similar results were also reported by Casierra-Posada and Cutler [28] who observed that prolonged waterlogging periods (25 d) also caused lower F v /F m , Y (II) and qP in cabbage (Brassica oleracea var. capitata) plants.…”

Physiological, biochemical, and metabolic changes in diploid and triploid watermelon leaves during flooding

“…Phenotypic as well as biochemical symptoms occurs due to flooding. Moreover, it has been reported earlier that flooding also leads to ethylene production ( Casierra-Posada and Cutler, 2017 ). Currently we observed a higher production of ethylene in 2X watermelon as compared to 3X watermelon as previously reported in perennial pepper weed ( Chen, 2002 ), avocado, as well as cotton ( Zhang et al., 2019 ) triggering leaf senescence ( Zhang et al., 2019 ).…”

Área foliar, contenido de clorofila, y masa seca de raíces en palmas de aceite (Elaeis guineensis Jacq.) afectadas por el disturbio del plumero

“…Palms affected by plumero significantly reduced the chlorophyll content and root growth. A decrease in the chlorophyll content in response to abiotic and biotic stress is manifested by foliar yellowing, followed by wilting, affecting photosynthesis (Munné-Bosch, 2008) and consequently, reducing plant biomass (Casierra-Posada and Cutler, 2017;Sánchez-Reinoso et al, 2019). Mandal et al (2009) stated that the chlorophyll content in diseased leaves of Plantago ovata affected by downy mildew was reduced by 24.39% in slightly chlorotic and 44.90% in severely chlorotic leaves as compared to healthy leaves, which appears to be one of the causes for the reduction of the photosynthesis process.…”
