Several wheat varieties were selected including high resistant(HR),moderate restant(MR),moderate susceptible(MS) and high susceptible(HS) ones,namely MN7213(HR),Jup73-Atd"s"(MR),SI2-Nb (MS) andVilela Mar.(HS).They were used as testing materials.The virulence ofthe fungus,Erysiphe graminis f.sp.tritici,collected from Shenyang,was identified with the virulence formula as 4/1,2,3a,3b,3c,5. After an inoculation of the fungus to wheat varieties of differentresistance and susceptibility in their three leaf stage(12 hours later)eachof.the varieties appeared to have peaks of enzymatic activities of phe-nylalanine ammonia lyase(PAL).The PAL activity of the resistant va-rieties was twice higher than the susceptible ones.The relay time wasalso longer being lasted 48 hrs.Peaks of enzymatic of susceptible varie-ties decrease rapidly approached to the normal level after 24 hrs.Theaccumulation of ferulic acid (preoursor of lignin)in the resistant varie-ty was not only faster (resistant 48 hrs,susceptible 72 hrs after ino-culation) but also greater.The amount of lignin were positively corre-lated with disease resistance of the tested wheat varieties:0.327%(HR),0.284%(MR),0.132%(MS) and 0.11% (HS).It is also found thatchlorogenic acid (phenolic phytoalexin,a metabolic of phenylalanine)accumulated rapidly accompanied with the increase of PAL activity.The times and quantities of chlorogenic acid accumulation were diffe-rent.For the resistant varieties to reach the peak accumulation (3.3μg/ml) needed 48 hrs and for the susceptible ones (1.35μg/ml)96 hrs. The results showed that there is a close relationship between theenzymatic activity of PAL as well as the chlorogenic acid and ligninand the resisstace of wheat to powdery mildew.

高抗白粉病的小麦品种MN7213,中抗品Jup73的Atd“S”,中感品种S_(12)—Nb及高感品种Vilela Mar.在幼苗3叶期用沈阳地区采集的小麦白粉菌(毒力公式为4/1,2,3a,3b,3c,5)接种。接种后12小时,各抗、感小麦品种均出现苯丙氨酸解氨酶的活性峰,但抗病品种酶的活性峰较高,为感病品种的两倍,持续时间也较长,达48小时;而感病品种酶的活性峰则迅速降低,24小时即接近于正常水平。接种后48小时,抗病品种出现木质素前体阿魏酸量的增加峰,而感病品种至72—96小时才出现阿魏酸的增加,且增加量较小。木质素含量的增加亦不相同,它与小麦品种的抗病性有着正相关性:高抗品种增加0.327%;中抗品种0.284%;中感品种0.132%,而高感品种仅0.11%。此外伴随着苯丙氨酸解氨酶活性的增加绿原酸(苯丙酸类代谢一种酚类植保素产物)也迅速积累,但不同抗病性的小麦品种积累的时相和量有所不同,抗病品种在接种后48小时即出现绿原酸的增长,较感病品种早48小时,而最高增长量是前者为3.30微克/毫升,后者只有1.35微克/毫升。上述结果表明小表品种对白粉病的抗性与苯丙酸类代谢的定速酶苯丙氨酸解氨酶活性有着密切...

In free-choice test, the number of eggs laid by whitebacked planthopper, Sogatella furci fera Horvath, on rice varieties was significaNT1y correlated -with the number of orientation of WBPH adults at 12 or 24 h after infestation. The number of eggs on MR ( moderate resistant) variety Mudgo was significantly higher than that on other varieties. In non-choice test, more eggs were laid on susceptible variety TNl and strain "9101" as compared with resistant and MR varieties including Mudgo. The WBPH adults were caged on Mudgo and TN1 respectively, the number of eggs or the amount of feeding on Mudgo was significantly less than that on TN1. While caged together, an almost equal number of eggs was laid on Mudgo and TNl, but the amount of feeding on Mudgo was appareNT1y lower. The analysis of nutrient content in rice sheath showed that there was significant positive correlation between the concentration of free amino acids (leucine, alanine, lysine, methionine, phenylalanine and asparagine ) and the fecundity of WBPH.

在自由选择试验中,白背飞虱(Sogatella furcifeta)在水稻品种上的产卵量与接虫12或24h后的栖息量呈极显著正相关;中抗品种Mudgo上的产卵量显著高于其它品种。在非自由选择试验中,感虫品种TN1和品系“9101”上的产卵量显著高于抗性和中抗品种(包括Mudgo)。分别罩笼时,Mudgo上的产卵量和取食量分别显著或极显著低于TN1;同罩一笼,产卵量差异不显著,取食量仍极显著低于TN1。稻株内游离氨基酸分析表明:白背飞虱的产卵量与亮氨酸和丙氨酸的含量呈极显著正相关,与赖氨酸,蛋氨酸,苯丙氨酸和天冬酰氨的含量呈显著正相关。
