“…The lowest dry matter allocation is related to the efficiency reduction in different physiological and biochemical processes as occasioned by the decrease or absence of oxygen in the soil, which affects respiration and fermentation, resulting in a minor quantity of energy that is available for growth and development (Borella et al 2013).…”

Plant growth analysis and seed vigor expression: effects of soil waterlogging during rye plant development

et al. 2015

This study aimed to evaluate the growth, assimilate partitioning and seed vigor expression of rye seeds subjected to waterlogging during development. The experimental design was completely randomized with six replications and three treatments. The treatments involved different waterlogging periods: a) no waterlogging; b) single waterlogging of three days; and c) two soil waterlogging periods of three days. The plants were collected at regular intervals of 14 days after emergence until the end of the growth cycle, measuring the dry matter accumulation and the leaf area for growth analysis and dry matter partition between the organs and number of flowers. The other calculated indices included the harvest index and relative seedling emergence rate originating from the seeds of plants that were maintained at field capacity and under the effect of soil waterlogging. Rye plants that were not subjected to waterlogging had a higher dry matter, dry matter production rates and harvest index compared to the plants under the effect of two soil waterlogging periods. Plants under the effect of two waterlogging periods showed drastic alterations in their growth rates and assimilate partitioning during development, and seed vigor expression was negatively affected when the plants were subjected to soil waterlogging.

“…Important metabolic routes include pyruvate as a substrate to produce lactate through lactate dehydrogenase (LDH), and a second route produces ethanol through two subsequent reactions catalyzed by pyruvate decarboxylase (PDC) and alcohol dehydrogenase (ADH) (Shingaki-Wells et al, 2011;Borella et al, 2013). Therefore, the degradation of certain proteins occurs in parallel with the production of others to aid in the fermentation process under hypoxic conditions, such as the increased activity of ADH and PDC enzymes (Christianson et al, 2009 Vol.…”

Erythrina velutina (mulungu) is an endemic species of caatinga found in Northeast Brazil. As a result of its rapid plant growth, the species may be an alternative for the recovery of degraded areas. Thus, the present study aimed to analyze the effects of irrigation with different field capacilities (FC): 20, 50 and 80% on plant growth, antioxidative enzyme activities, membrane lipid peroxidation and organic solute contents in mulungu seedlings under greenhouse conditions. The experiment was carried out at Instituto Federal Educação, Ciência e Tecnologia do Ceará (IFCE)-Campus Maracanaú, Ceará, Brazil. Under the presented experimental conditions, E. velutina plants showed higher growth variables (dry matter yield and leaf area) when submitted to daily irrigation of 50% of FC. Irrigation at 20% of FC caused a small water deficit. However, 80% of FC watering may have resulted in an excess of water. In general, despite the reduction in plant growth in plants irrigated at 20% of FC, the activities of the antioxidant enzymes did not differ substantially between treatments. In general, the lowest organic solute contents were detected in irrigations at 20 or 80% of FC.
