TRANI, P.E.; HAAG, H.P.; DECHEN, A.R. and CATANI, C.B.. Dry matter production and nutrient exportation by pruned leaves and branches of apple trees. An. Esc. Super. Agric. Luiz de Queiroz [online]. 1981, vol.38, n.1, pp. 415-434. ISSN 0071-1276. http://dx.doi.org/10.1590/S0071-12761981000100035.
A trial was conducted on Latossol Vermelho Escuro Orto (Orthox) at Buri, State of São Paulo, Brazil. The material was collected from 'Ohio Beauty1 and 'Brasil1 apples trees grafted on 'Doucin'; the trees were 3-4, 4-5 and 6-7 years old. The authors concluded that at the dormant period differen ces were observed on the dry matter production as well on the nutrients exported by the leaves and branches of the two varieties. Branches exported higher amounts of P, Ca, B, Cu and Zn. Larger quantities of N, P and Mn were exported by the 1 eaves.
