Responses of Typha australis (Schum. & Thonn.) to a cutting of the stem
Abstract
Typha australis (Schum. and Thonn.) is an invasive species that has grown considerably in northern Senegal. It is increasingly encountered in the Niayes of intensive farming. Typha causes inconvenience to human and the ecosystem. The control of the species is essentially made by cuttings. The results of which are inconclusive. The aim of this study assesses under experimental conditions the responses of Typha to a cutting of the stem. The plants harvested in the Niayes were transplanted into containers filled with sand of defined characteristics. After an acclimation period, the plants were divided into 2 groups: a control plants and a cut plants applied to 5 terms of 3 repetitions. After cutting, the regeneration is complete. The cut has no effect on Typha. No significant difference was found for the appearance of regrowths beyond the 51st day; the plant height, the diameter, the fresh matters of the aerial parts and AP / UP ratio beyond the 62th day, and the dry matters of the aerial parts and underground parts beyond the 73th day. A single cut does not seem to have any effect on the growth. On the contrary, it stimulates in the long term the species. Typha australis develops a strong root system that ensures rapid regeneration. This ability to react to a cutting is partially responsible for its proliferation.
