试验测定了分离自中国小麦赤霉病常发生地区病麦穗上的47个禾谷镰刀菌(Fusarium graminearum)菌株的产毒素能力。结果表明,它们可以产生25种包括单端孢霉烯族化合物(Trichothecenes)、倍半萜类化合物(Sesquiterpenes)、赤霉烯酮(Zearalenone)和丁烯羟酸内酯(butenolide)等类的已知次生代谢物。这些菌株属于化学型I,其中,来自我国温暖麦区的菌株都属化学型IA(deoxynivalenol,3-acetyl),并在气候冷凉地区发现化学型Ib(deoxynivalenol,15-acetyl)菌株。

本文研究了一种叶甲(Timarchamaritima)的种群变异性,在此物种的整个分布范围内,沿法国大西洋海岸取选10个种群,测定个体大小、生育力、寄生量、性比、交配模式几个变量,各变量在不同种群间呈现显著差异。我们的调查结果也表明:原生生物(簇虫,Gregarinamunieri)的寄生是影响***生态习性的主要因素;这种甲虫的交配模式与寄生量有关,这种交配模式3年前已在一个高寄生种群内发现;个体大小与交配的关联不显著,即便是在没有寄生的种群中也是这样;在不同种群间,寄生感染程度也是一个有力的指示量,可以预示雌性个体的生育力变化;相反,不管观察什么种群,外寄生种(蜱螨,Pseudamansiachrysomelinus)(Acari:Canestriniidae)的作用很小。这项研究表明:在研究种群生态学时,需要同时观察寄生物的影响。

Undoped and be-doped InAs（1–x）Sbx（0 ≤ x ≤ 0.71） epitaxial layers were successfully grown on lattice mismatched semi-insulating Ga As（001） substrate with 2° offcut towards 〈110〉. The effect of the In As buffer layer on the quality of the grown layers was investigated. Moreover, the influence of Sb/In flux ratio on the Sb fraction was examined. Furthermore, we have studied the defects distribution along the depth of the In As Sb *** addition, the p-type doping of the grown layers was explored. The In As Sb layers were assessed by X-ray diffraction, Nomarski microscopy, high resolution optical microscopy and Hall effect measurement. The In As buffer layer was found to be beneficial for the growth of high quality In As Sb layers. The X-ray analysis revealed a full width at half maximum（FWHM） of 571 arcsec for In As0.87 Sb0.13. It is worth noting here that the Hall concentration（mobility） as low（high） as 5 × 10^（16）cm^（-3）（25000 cm^2 V^（-1）s^（-1）） at room temperature, has been acquired.

With the discovery of molecular markers and marker assisted selection technology, the research has entered into a new era and has made it possible to develop new and more informative PCR-based markers, including SSR, and to further facilitate the use of markers in tomato breeding. The present study is a step to introduce a new SSR marker (TOM-144) which was deduced after evaluation of eight microsatellite loci amongst the twenty-one different tomato cultivars. The marker selected was inherited and segregated in mendelian fashion as demonstrated in successive generation of a cross between parent cvs. H-24 x GT-2.
