ALDANA, Fernando; GARCIA, Pedro Nel  and  FISCHER, Gerhard. Effect of waterlogging stress on the growth, development and symptomatology of cape gooseberry (Physalis peruvianaL.) plants. Rev. acad. colomb. cienc. exact. fis. nat. [online]. 2014, vol.38, n.149, pp.393-400. ISSN 0370-3908.

Climate 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.

Keywords : Hypoxia; leaf area; dry weight; symptoms.
