“…The negative effect of flooding in plant growth, leaf length, and number of leaves from LA1579 genotype could be due to reduction of photosynthetic rate. Reduced plant growth due to flooding was also observed in Annona species (Nunex-Elisea, 1999), Panicum antidotale (Ashraf, 2003), Paspalum dilatatum (Vasellati, 2001) and Genipa americana seedlings (Mielke, 2003), tomato (Walter, 2004); all of these plant species showed growth reduction to varying extents in waterlogged conditions. CLN2498E and CA4 genotypes exhibited high adventitious root formation above soil surface compared to LA1421, and LA1579.…”

“…As a consequence, the adventitious roots of CLN2498E and CA4 genotypes can obtain oxygen from air and absorb nutrients; this characteristic may play an important role in its adaptation to flooding conditions. In a similar study on tomato, Walter et al, (2004) demonstrated that tomato had the most vigorous adventitious root growth compared to cucumber, zucchini and bean. Mano and omori (2007) reported that Dicotyledonous plants (e.g., soybean and tomato) generally form taproot system but develop adventitious roots under flooding conditions (McNamara and Mitchell, 1990;Bacanamwo and Purcell, 1999).…”

A greenhouse experiment was conducted to investigate the effect of flooding on two tomato cultivars and two wild related species. Forty days old tomato plants were subjected to a continuous flooding stress of different durations: 0, 2, 4 and 8 days. Plant pots were placed inside larger plastic pots; they were irrigated with excessive quantity of tap water at 25 0 C so that the level of water above the surface of soil was 15 cm throughout the flooding period. At the bottom of each plastic pot a drilled hole allowed complete drainage of the pot after flooding. Parameters studied include plant height, number of leaves, leaf length, chlorophyll fluorescence, chlorophyll content, wilting, leaf senescence, adventitious root formation, number of flowers and fruits from cluster 2 to 6, average weight per fruit, fruit length and width, total fruit weight from cluster 2 to 6, total yield per plant. LA1579 genotype was more subjected to the deleterious effect of flooding on almost all the parameters studied. Therefore LA1579 genotype is flooding sensitive. Genotypes CLN2498E, and CA4 showed high tolerance to flooding while LA1421 genotype was tolerant to some extent. This experiment provides information that could help in the identification of physiological and agronomical parameters associated with flood-tolerance in vegetables.

“…The marked leaf area decrease in the cape gooseberry plants waterlogged for 6 and 8 days can be attributed to a reduction in the photosynthetic rate, as observed in solanaceous species such as the tomato (Walter et al, 2004), due to stomatal closure (Kozlowski and Pallardy, 1997) and the adverse effects of this stress on the photosynthetic capacity (Bradford and Yang, 1981), which Kozlowski and Pallardy (1997) associated with changes in enzyme carboxylation, reduced chlorophyll content and lower leaf area as caused by an inhibited formation, expansion, injury, and abscission of leaves.…”

Waterlogging stress in cape gooseberry plants 393 Rev. Acad. Colomb. Cienc. Ex. Fis. Nat. 38(149) AbstractClimate change has altered normal rainfall cycles; causing the flooding of arable land and, thus, affecting agricultural production in Colombia. Two-month-old cape gooseberry plants, propagated by seeds, were subjected to different durations of continuous waterlogging in a greenhouse: 0, 2, 4, 6 and 8 days, with evaluations up to 50 days. The plants were placed in ditches covered with polyethylene and filled with water up to 5 cm above the substrate surface of the pots. The parameters evaluated were: plant height, leaf area, stem diameter, dry weight of the aerial part, root and reproductive organs, and general symptoms following a wilting scale. The 6 and 8-day-waterlogged plants were the most affected by the flooding conditions, presenting the lowest values for all the measured variables. Due to the oxygen stress in the root zone, the plants showed yellowing, epinasty, necrosis and abscission of the leaves, more so in the 8-day-waterlogged plants.Key words: Hypoxia, leaf area, dry weight, symptoms. Efecto del estrés por anegamiento sobre el crecimiento, desarrollo y sintomatología de plantas de uchuva (Physalis peruviana L.) ResumenEl cambio climático ha alterado el ciclo normal de las lluvias, inundando así las tierras arables y afectando la producción agrícola en Colombia. Plantas de uchuva, de 2 meses de edad, y propagadas por semilla, fueron sometidas bajo invernadero a diferentes duraciones de anegamiento continuo: 0, 2, 4, 6 y 8 días y evaluaciones hasta 50 días. Las plantas se colocaron en zanjas cubiertas con polietileno que se llenaron con agua hasta 5 cm por encima de la superficie del sustrato contenido en las macetas. Los parámetros evaluados fueron: altura de planta, área foliar, diámetro del tallo, pesos secos de parte aérea, raíz y órganos reproductivos y escala de síntomas generales de marchitamiento. Las plantas anegadas durante 6 y 8 días presentaron los valores más bajos para todas las variables evaluadas. Debido al estrés por falta de oxígeno en la rizósfera las plantas mostraron amarillamiento, epinastia, necrosis y abscisión de hojas, sobre todo en las de 8 días anegadas.Palabras clave: hipoxia, área foliar, peso seco, síntomas.

“…Tomato plants had ability to develop adventitious roots which attributed to its tolerance to excess water conditions (Walter et al, 2004). Adventitious root formation compensated for loss of the original roots due to hypoxic condition below water table (Ezin et al, 2010).…”

It was presumed that shallow water table restricted leaf growth and some water-related parameters; therefore, they can be used as indicators of plant stress due to the water table condition. Objective of this research was to evaluate morphological stress indicators in tomato plants exposed to shallow water table. The research was conducted in two stages: (1) developing reliable LA estimation model from June to September 2016; as pre-requisite for (2) calculating and evaluating the morphological indicators for stress due to shallow water table treatments, conducted from February to May 2017. Treated plants were placed inside experimental pools. Each treatment was done by partially submerging growing substrate to the targeted water tables at 5 cm and 10 cm below surface of the substrate. Untreated control plants were kept outside the pools. Zero-intercept linear model was the selected model for leaf area estimation after evaluating 15 combinations of five regression models and three predictors. Results of this study indicated that steady water table at 5-cm and 10-cm depth did not restrain relative leaf expansion rate (RLER) and there was no significant difference in specific leaf fresh weight (SLFW) and specific leaf water content (SLWC) between treated and untreated plants, measured prior to, during, and after recovery from shallow water table treatments. In conclusion, if position of water table was steady, the shallow water table at 5-cm depth or deeper did not affect tomato growth.
