While under natural low temperature (10-20℃), a great deal of abnormalities, including micro nucleoli, scattered and lagged chromosomes and anaphase bridges were detected during PMC meiosis, even though the abnormalities were different between the two cultivars; the ratio of micro nucleoli was 22.88% of average, which was obviously higher than that of control (4.56% of average under normal temperature); and the ratios of univalent and multivalent in diplotene, which increased seriously, were 8.82% and 17.65% of Tainong 1, and 14.52% and 24.19% of Irwin under natural low temperatures.

低温（10~20℃）条件下，减数分裂过程中核仁的行为发生大量异常，微核仁的平均检出率高达22.88%，明显高于常温条件下的平均4.56%；双线期单价体和多价体的发生频率有明显增加，其中台农1号为8.82%和17.65%，Irwin为14.52%和24.19%；减数分裂中期Ⅰ、Ⅱ及后期Ⅰ、Ⅱ均观察到落后染色体，其中台农1号异常率为12.73%、5.63%、15.79%和4.76%，Irwin为11.11%、7.61%、9.52和6.38%。

It was worth to note that the HI titer of monovalent vaccine immunized group challenged with the same type reached the peak earlier than that challenged with different type virus, whereas there was no such difference among multivalent vaccine immunized groups. It suggested that NDV immunogenicity among epizootic isolates and vaccine strains were also variable in some extent.
