In order to solve the problem of Botryosphaeria dothidea on resistance to traditional fungicides, bio-assay tests were made for 6 fungicides including 10% water-dispersible granules of difenoconazole, 250 gL^(-1) azoxystrobin suspension concentrate etc. against B. dothidea in laboratory. Field tests of these fungicides with different concentrations were made for control of the disease on apple trees.

Most of water-soluble cyanine dyes have -SO3H and –COOH in their molecules, which will influence the biomolecules' functional characters. A new kind of water-soluble cyanine dyes with several cations in molecules were designed and synthesized, preparation conditions of intermediate and dyes were researched and optimized, the yield of dye is 25%. The novel kind of cyanine dye are water-soluble , spectrum characters was researched , all the dyes were charactered by 1H NMR and TOF-MS, spectrum in different solvent of novel dyes were focused on, one of the kind dyes show higher fluorescence quantum yield than the result reported. Because of several cations in the structure, it is promising when used in DNA assay and other bio-assay field.

大多数水溶性的菁类荧光染料分子结构中都带有-SO3H和-COOH等基团，过多的阴离子的引入容易造成对生物分子的功能属性的影响，本论文设计并合成了分子结构中带有多个正电荷的水溶性的一类新型菁染料，考察并且研究了中间体和染料的合成条件，最终的目标产物产率达到25％，染料通过了质谱和核磁的表征，新型的染料具有良好的水溶性，研究了新染料在多种溶剂的的光谱性质，其中一种染料的在水中的荧光量子产率比文献报道得到了提高，由于富集了正电荷，这类菁染料在DNA标记等生物中有一定应用前景。
