Serological properties of the bitter gourd mosaic virus.

摘要

Experiments were conducted to identify bitter gourd (Momordica charantia) mosaic virus by serological methods. The results of microprecipitin tests showed that antigens of bitter gourd mosaic virus isolate I (obtained from inoculated plants in the glasshouse), bitter gourd mosaic virus isolate II (obtained from diseased plants in the field), cucumber mosaic virus, pumpkin mosaic virus and snake gourd mosaic virus produced a dense precipitate with the antiserum specific to bitter gourd mosaic virus.This indicates the serological relationship of bitter gourd mosaic virus to the viruses causing cucumber mosaic, pumpkin mosaic and snake gourd mosaic found in Kerala, India. The antiserum titre was between 1:4096 and 1:8192 and the virus end point wasbetween 1:1024 and 1:2048.
