After an inoculation of Erysiphe graminis f.sp.tritici to wheat varieties of different disease resistance,the peroxidases appeared to have two peaks of enzymatic activities.It was found that the first peak appeared at conidiophere formation stage of this pathogenic fungus,and the second was at the conidial stage.The relative enzymatic activities of the first peak were positively correalated with disease resistance of the tested wheat varieties.The results of scanning on the SDS-polyacrylamide gel electrophoresis...

After an inoculation of Erysiphe graminis f.sp.tritici to wheat varieties of different disease resistance,the peroxidases appeared to have two peaks of enzymatic activities.It was found that the first peak appeared at conidiophere formation stage of this pathogenic fungus,and the second was at the conidial stage.The relative enzymatic activities of the first peak were positively correalated with disease resistance of the tested wheat varieties.The results of scanning on the SDS-polyacrylamide gel electrophoresis showed that there is a close relation between the high molecular weight (above 28,000 dalton) enzymatic band and disease re-sistance of the wheat plants.The high resistant variety,Mn 7213 hadone more band than the others in patterns of the isoenzyme.It is pro-bably due to the expression of the disease resistant gene.In isoenzymaticpattern of high susceptible variety,Vilela Mar.,only certain individualband was more intensive than,others.

The germination and infection of conidia of brown spot needle blight fungus (Lecanosticta acicola) on pine needles were observed under scanning electron microscope (SEM). Results showed that the conidia on the needles of Pinus massoniana, P. elliottii and P. thunbergii all germinated in the same way, and their germ tubes invaded into the needles through stomata, mostly 3-4 days after inoculation. Tests indicated that the peroxidase activity in needles of the resistant host P. Massoniana, increased rapidly 5 days after inoculation, but there were no evident changes of such activity in the needles of the susceptible hosts P. elliottii and P. thunbergii. There were no prominent relations between the peroxidase activity levels and disease resistance in all these three species of pines. The levels of peroxidase activity in needles of different individuals of P. elliottii also did not reflect their corresponding susceptibilities.

用扫描电镜观察松针褐斑病菌(Lecanosticta acicola)分生孢子在针叶表面萌发和侵入途径及时间,结果表明分生孢子在马尾松、湿地松和黑松针叶表面均能萌发,芽管通过针叶表面的气孔侵入针叶,侵入盛期是接种后3~4天。抗病的马尾松在感病后的针叶中过氧化物酶活性能迅速提高,而感病的湿地松和黑松针叶中过氧化物酶活性没有明显变化。马尾松、黑松和湿地松针叶中过氧化物酶活性水平与它们本身的抗病性无关,湿地松不同单株的针叶中过氧化物酶活性水平也不能反映它们相应的感病性。
