摘    要:采用网罩麦长管蚜Sitobion miscanthi (Takahashi)的观测方法,对15个不同抗性小麦品种(系)进行苗期不选择性、抗生性测定;选择其中5个代表性品种(系)观测了田间扬花期麦长管蚜的产蚜量,测定了小麦旗叶和穗部中单宁与槲皮素的含量以及麦长管蚜羧酸酯酶(CarE)与谷胱甘肽S-转移酶(GST)的活性。结果表明,代表性品种(系)在苗期对麦长管蚜的产蚜量的影响与扬花期的呈显著正相关(r=0.956*)。穗部槲皮素的含量与不同抗性品种(系)上的产蚜量呈显著负相关(r=-0.941*);单宁含量在不同抗性品种(系)间存在显著差异,其含量变化与产蚜量无显著相关。取食不同抗性品种(系)后麦长管蚜的CarE和GST酶活力存在显著差异。结论认为小麦不同品种(系)对麦长管蚜产蚜量(生殖力)的抑制作用是其抗蚜的重要特性,尤其是中4无芒和冀保一号对麦长管蚜抗生性较强。

关 键 词:麦长管蚜  小麦品种  抗生性  次生物质  羧酸酯酶  谷胱甘肽S-转移酶

Abstract:The behavior of Sitobion miscanthi(Takahashi)on 15 different tolerant varieties was observed and the antixenosis and antibiosis of these wheat varieties in seedling were tested by using aphids confinement test.Selected five characteristic varieties,we recorded the fecundity of aphids in field during anthesis,assayed the content of quercetin and tannin in flag leave and ear,and detected the activity of carboxylesterase(CarE)and glutathione S transferase(GST)of the aphids on these varieties.The results indicated the effects of the five selected wheat varieties in seedling and anthesis on the fecundity of aphids were significantly positively correlated(r = 0.956*).The correlation between quercetin in ear of wheat and the fecundity of aphids on different wheat varieties was significantly negative(r =-0.941*).The tannin contents of different wheat varieties were significantly different,but showed no significant correlation with the fecundity of aphids.The contents of carboxylesterase(CarE)and glutathione S-transferase(GST)of aphids feeding on different wheat varieties were significantly different.We concluded that different varieties had strong inhibiting effects on the fecundity of S.miscanthi,especially with the effects of Zhong 4 wumang and Jibao No.1 stronger.
Keywords:Sitobion miscanthi  wheat variety  antibiosis  allelochemicals  carboxylesterase  glutathione S-transferase
