Behavior and adaptation of the Introduction to a new ecosystem of Ladenbergia oblongifolia (Mutis) L. (Cinchona tree), Ucayali-Perú

Abstract

Irresponsible anthropogenic activities and climate change have been accelerating the extinction of biodiversity and an alternative solution is to encourage the introduction of species to new ecosystems in this way expanding their geographical distribution. The objective of the work was to know the behavior and adaptation of the introduction to a new ecosystem of Ladenbergia oblongifolia (Mutis) L. (Quina tree), and for which a pure plantation was installed exposed to three treatments, T1 being: 100% light (open field) T2: 35% light and T3: 10% light, for this 65% Raschel mesh and 90% shadow were used, the design was random blocks. The results showed that the T3 treatment (10% light) is the one that allowed the lowest mortality (31.25%) of the planted plants, as well as the best growth in height (35.5 cm), plant diameter (7.25 mm), emission of sprouts (3.5 sprouts), number of leaves (5.25 leaves) and the one that led to the best phytosanitary status (level 3) of the planted plants. It is concluded that Ladenbergia oblongifolia (Mutis) L. (Quina tree), introduced to the Ucayali region, is adaptable as long as the amount of light that reaches directly to the plant is controlled (approximately 10%). It is recommended not to install in open fields.
