英语. The vitro characteristics of PVY in Henan Province were studied by biological methods. The result showed that the dilution muttiple end point of PVY in Henan Province was 10~(-6)～10~(-7),its thermal inactivation point was 70～75 ℃,and its longevity in vitro was 4～6 d.By study in the interaction between PVY and CMV,TMV,it was found that the mixed inoculated symptoms were more serious than the single inoculated symptoms,and the symptoms between the treatments were different.
