TEIXEIRA, Paulo de Tarso Lima; SCHAFER, Gilmar; SOUZA, Paulo Vitor Dutra de  and  TODESCHINI, Abel. Vegetative development of citric rootstocks produced in different containers. Cienc. Rural [online]. 2009, vol.39, n.6, pp.1695-1700.  Epub June 19, 2009. ISSN 0103-8478.

This work aimed to compare the vegetative development of citric rootstocks sowed in isoprene trays on in stiff plastic tubes irrigated by capillarity. The experimental design was a randomized blocks with split plot scheme, testing both containers at the plot (tubes and isoprene trays) with 120cm³ of substrate volume, and, in the subplot, three citric rootstock varieties (trifoliate orange - Poncirus trifoliata [L.] Raf.), citrange FEPAGRO 'C37' - Poncirus trifoliata (L.) Raf. x Citrus sinensis (L.) Osbeck.] and tangerine 'Sunki' - C. sunki hort. ex Tan.). Twenty plant per subplot were used and three replications. After 150 days of sowing, plants cultivated in trays showed higher vegetative development. Rootstocks FEPAGRO 'C37' and trifoliate orange presented similar height growth and both were higher than tangerine 'Sunki'. Citrange FEPAGRO 'C37' showed longer diameter and dry mass accumulation in relation to other rootstocks.
