Descripción
In Colombia, the cape gooseberry, a plant found in cold tropical climate zones, is adapted to altitudes between 1800 and 2800 masl and prefers an average annual temperatures ranging from 13 C to 16 C. It is a very rustic plant, and thus habituates well in a wide range of ecological conditions. Very high temperatures (≥ 30 C) hinder the flowering, while frost depresses new growth of the plant, which recovers after a short freeze. In tropical highlands, high UV radiation reduces stem length growth of the plant, and which develops a shallow root system to take advantage of midday soil heating. The prolonged rainy season, or rain immediately after a dry season, favors fruit cracking, which can be relieved with optimal levels of Ca, Mg and B in the tissue. The plant can survive up to 4 days of waterlogging of the roots, while dry periods reduce growth and fruit production. In commercial cape gooseberry fields, loose soils, sandy loam or clay loam, with an effective rooting depth of 60 cm are optimal, while a deficiency of elements such as N, K and B are the most detrimental to growth and fruit production. Global warming requires the selection of sites with moderate temperatures and new adapted genotypes.
