Se investigo en camaras de crecimiento la funcion de la temp. y la concn. virica en el desarrollo de necrosis apical y de muerte de plantulas por BYMV. La temp. controlo el desarrollo de necrosis apical en frijol infectado por BYMV. El porcentaje de plantas infectadas que desarrollaron necrosis apical aumento a temp. entre 16 y 24 grados C, pero disminuyo drasticamente a temp. de 24 a 28 grados C. Temp. superiores a 28 grados C inhibieron el desarrollo de necrosis apical en el frijol infectado. Temp. entre 16 y 24 grados C favorecieron la multiplicacion de BYMV y, por tanto, hubo mayor titulacion virica contribuyendo en parte a la severidad y al porcentaje de necrosis apical. La concn. de inoculo original afecto notoriamente la muerte de las plantulas de frijol infectadas por BYMV. (RA-CIAT) spa
The role of temperature and virus concentration on tip necrosis and seedling death of bean yellow mosaic virus (BYMV) was investigated in growth chambers. The development of tip necrosis in BYMV-infected beans is controlled by temperature. The percentage of infected plants that developed tip necrosis increased between 16 and 24 C, but decreased drastically from 24 to 28 C. Temperatures higher than 28 C were inhibitory to the development of tip necrosis in BYMV-infected beans. Temperatures between 16 and 24 C that favored BYMV multiplication resulted in higher virus titer and contributed in part to the severity and percentage of tip necrosis. Death of BYMV-infected bean seedlings was strongly influenced by original inoculum concentration. (AS) eng
