It is now known that the effects of tristeza disease were recognized prior to 1900. In the early 1890's when sour orange, Citrus aurantium Linn., was first used as a rootstock in South Africa, it was observed that sweet orange, C. sinensis (Linn.) Osbeck, and mandarin orange, C. reticulata Blanco, trees budded on sour orange rootstock usually died or declined severely within two or three years. Inasmuch as these two scion varieties, and also lemon, C. limon (Linn.) Burm., grew satisfactorily on Rough lemon, C. jambhiri Lushington, this last-naned variety was used almost exclusively thereaftter as a rootstock in South Africa. For many years the failure of sweet orange trees on sour orange rootstock in South Africa was attributed to incompatibility between sourorange and certain scion varieties, After a study of the citrus industry of South Africa in 1924-25, Webber rejected the use of uncongenial strains of sour orange as a cause of the tree failures. His studies led hin to the conclusion that the disorder was an infectious disease. In a later publication Webber discussed the tristeza disease of Argentina and Brazil as the same as the disease in South Africa and suggested a virus as its cause. As early as 1928, Toxoppeus in, Java, began studies of what apppeared to be the same disease as that in South Africa.He also eliminated physiological and environmental factors as causes of the dissorder. |

B deficiency is one of the most limiting factors for the growth of Eucalyptus spp. in Brazil, especially in the cerrado region, where there is the greatest expansion of forest production of the species. Based on multi or hyperspectral sensors and digital image processing techniques, the application in diagnosis is fast, nondestructive and local in applications with plants. Our hypothesis is that the use of orbital sensors through the spectral bands is sensitive in the diagnosis of B deficiency or toxicity in adult Eucalyptus spp. in the Brazilian Cerrado region. |
