根据高粱属核糖体基因转录间隔区(ITS)序列设计通用引物S9/S3,分别扩增了假高粱及其几个近似种的ITS区段,并对PCR产物进行了序列测定和分析.扩增的序列长度为559~564bp.序列分析的结果表明S. halepense、 S. silk、 S. vulgare×S. sudanense、 S. vulgare、高粱S. bicolor等属于同一聚类组,亲缘关系比较近,同源性为97.9%~100%.S. nitidum和S. versicolor属于另一个聚类组,亲缘关系比较近,同源性为97.7%.S. halepense和S. nitidum、S. versicolor ITS区序列差异大,亲缘关系较远,同源性仅为90.3%.序列分析结果支持S. nitidum属于Parasorghum区组.  相似文献

苏芸金杆菌以色列变种Bacillus thuringiensis var.israelensis(以下简称B.t.i.)对蚊幼虫毒力强,杀虫效果好。世界卫生组织已向世界各国发起了进行B.t.i.杀虫效果、标准化及安全性试验的倡议。到目前为止,B.t.i.对动物的安全性试验,国外仅有某些方面的报道,国内尚未见有系统的报告。因此,进行这方面的试验研究有其实际意义。我们在开展B.t.i.灭蚊试验研究的基础上,进行了B:t.i.对脊椎动物的安全性试验,现将结果报道如下。  相似文献

Microtopography may affect the distribution of forests through its effect on rain redistribution and soil water distribution on the semi-arid Loess Plateau,China.In this study,we investigated the characteristics of microtopography on two shady slopes(slope A,5 hm2,uniform slope;slope B,5 hm2,microtopography slope) and surveyed the height,the diameter at breast height and the location(x,y coordinates) of all selected individual trees(Robinia pseudoacacia Linn.,Pyrus betulifolia Bunge,Populus hopeiensis Hu & Chow,Armeniaca sibirica Lam.,Populus simonii Carr.and Ulmus pumila Linn.) on slope A and slope B in the watersheds of Wuqi county,Shaanxi province.Subsequently,the effects of microtopography on the spatial pattern of forest stands were analyzed using Ripley’s K(r) function.The results showed that:(1) The maximal aggregation radiuses of the tree species on the uniform slope(slope A) were larger than 40 m,whereas those of the tree species on the microtopography slope(slope B) were smaller than 30 m.(2) On slope B,the spatial association of R.pseudoacacia with P.betulifolia,A.sibirica,P.simonii and U.pumila varied from being strongly negative to positive at microtopography scales.The spatial association of Populus hopeiensis Hu & Chow with U.pumila also varied from being strongly negative to positive at microtopography scales.However,there was no spatial association between P.betulifolia and P.hopeiensis,P.betulifolia and A.sibirica,P.betulifolia and P.simonii,P.betulifolia and U.pumila,P.hopeiensis and A.sibirica,P.hopeiensis and P.simonii,A.sibirica and P.simonii,A.sibirica and U.pumila,and P.simonii and U.pumila.On slope A,the spatial association between tree species were strongly negative.The results suggest that microtopography may shape tree distribution patterns on the semi-arid Loess Plateau.  相似文献

自然条件下,对5种胡枝子属植物光合作用日进程和光响应进行了观测,结果表明5种胡枝子净光合速率的日变化在夏季表现为双峰曲线,有光合"午休"现象。牛枝子、达乌里胡枝子、阴山胡枝子、截叶胡枝子和尖叶胡枝子日平均光合速率分别为3.75μmol CO2.m-2.s-1、3.55μmol CO2.m-2.s-1、3.37μmolCO2.m-2.s-1、4.45μmol CO2.m-2.s-1、3.78μmol CO2.m-2.s-1;光补偿点分别为38.23μmol.m-2.s-1、43.24μmol.m-2.s-1、13.75μmol.m-2.s-1、36.11μmol.m-2.s-1和45.46μmol.m-2.s-1;光饱和点分别为:1225μmol.m-2.s-1、1262.6μmol.m-2.s-1、1287.5μmol.m-2.s-1、1462.5μmol.m-2.s-1和1312.5μmol.m-2.s-1显示了阳生植物特性。表观量子效率分别为0.034、0.037、0.32、0.036和0.033,可看出5种胡枝子叶片光能转化效率低,其对光的响应敏感性较差。因此,这5种胡枝子对光环境适应能力强,适合在较大范围栽植。  相似文献
