Influência de recipientes e substratos na qualidade de mudas de Cumaru (Amburana cearensis (Arr. Cam.) A.C. Smith).

Abstract

Amburana cearensis (cumaru) presents a major agricultural, Forestry, ornamental and medicinal is important to know about biometrics seed, containers and substrate for the quality of seedlings of this species. It aimed, through the conduction of the experimental works, to evaluate the effect of the three subtract different and container size different about the initial development of Amburana cearensis. The rehearsals were led Campus of Pici of Federal University of Ceará (UFC), in Fortaleza-CE, during the period from June to November of 2008. The experimental outline was entirely random in 3 x 3 factorial design, whit three container [big (28 x 40 cm)-R1; average (: 20 x 30 cm)-R2 and small (15 x 25 cm)-R3, and totally three subtract [S1 (2 soil + 1 red sand + 1 carnauba butt); S2(2 soil + 1 commercial organic compost polefértil ) and S3(2 soil + 1 red sand + 1 humus)] the used nine treatments with four repetition of seven container. The experiment showed that the treatments affected the growth of the variables used in the evaluation of responses in the plant. The size containers not influence the growth of seedling height of cumaru. The Container and substrate interaction significant in growth and development of height, number of leaf, length of root, fresh and dry weight of shoot. Does container x substrate interaction was not significant in the development diameter of the collection, diameter of xylophodio, fresh weight of root, the root dry mass and index quality of Dickson. Size large containers with substrate S3 majority provide greater growth of seedlings, over there, the small container com substrate S1 and S2 minority provide greater growth seedling. To produce good quality of cumaru, it is recommended to use a large container with substrate S3 in long time, and use medium and small container with the same substrate short time.
