Improvements made to a tube for the production of cloned conilon coffee seedlings, more precisely, it is a tube (1) for the production of conilon coffee seedlings； said tube (1) is of the type formed by tubular trunk body (2) with wide upper opening (2a) which has a diameter (x2) greater than the diameter (x) of the lower base (2b)； the opening edge (2a) includes outer peripheral collar (2c) that can be accommodated on the support grid (g) or other suitable support； the inner surface (2d) of the tubular body (2) comprises multiple longitudinal and thin friezes (f)； Said tubular trunk body (2) of the tube (1) provides for the multiple ribs (f) to be formed by angled walls (2e) which extend at a greater length (w) in a coplanar manner relative to the edge (2c) of the aperture (2). 2a), reducing in length to zero (y) near the bottom base (2b)； near the lower aperture (2b) interconnect links (2g) develop between the base member (mb) and the inner wall of the body (2) tubular body (2)； the interstices resulting from the spacings between the liames (1) and the base member (mb) configure annular tears (2f) for the water flow, as well as the oxidation point for paralysis of the seedling root growth； each lyme (2g) is formed by oblong and bulging projection, with the apex facing upwards and the lyme part is wider and coplanar with the tears (2f), configuring seedling root guides for the base member (mb) and growth impediment structure thereof； the base member (mb) is configured by projection (2h) into a cone trunk with the smallest diameter (d1) directed to the edge of the upper aperture (2a) and the ridge has a hole (2i).aperfeiçoamentos introduzidos em tubete para produção de mudas clonadas de café conilon, mais precisamente trata-se de tubete (1) para a produção de mudas donas de café conilon； dito tubete (1) é do tipo formado por corpo tronco tubular (2) com ampla abertura superior (2a), a qual apresenta diâmetro (x2) maior que o diâmetro (x) da base inferior (2b)； a bor
