SANTOS, Antonio A. dos et al. Effect of the Soursop yellow blotch virus on the growth and yield of soursop diseased plants. Summa phytopathol. [online]. 2007, vol.33, n.1, pp. 90-92. ISSN 0100-5405.  http://dx.doi.org/10.1590/S0100-54052007000100015.

Growth and yield losses on soursop plants due the Soursop yellow blotch virus (SYBV) disease were studied during the years 2000 to 2004 in an experiment with two treatments: healthy and SYBV diseased plants. The experiment was disposed in a completely randomized block design with 8 replications with 4 plants per plot. Plant height, trunk diameter, number and weight of fruits were evaluated annually. Data, as plot means, was computed, statistically analyzed and compared by F test. Plants of both treatments were obtained by grafting with buds from healthy and SYBV infected plants. The disease caused percent reductions of 65.11, 46.72, 94.7 and 99.2 in plant height, trunk diameter, in fruit number and fruit weight, respectively.
