Isolates isolated from maize and 3 isolates from rice, wheat, adzuki bean in ten provinces were identified as Curvularia lunata. Based on the culture characters, such as color of colony, aerial myeelia, the number of conidia, there were some difference among 43 isolates. Meanwhile, five types of conidium were compared in culture characters and virulence. In each single conidia culture there were different morphic conidia also and no difference in virulence was found among five single-conidium cultures.

收集并分离我国10个省的玉米叶斑病病原物40个以及水稻、小麦、红小豆上的C.lunata分离物3个；对分离物进行培养性状、产孢能力及形态特征的研究结果表明：分离物在菌落颜色、气生菌丝的繁茂程度、产孢量的多少等方面存在明显的差异；同一分离物内分生孢子在形态方面有差异，不同形态单孢继代培养后仍出现多种形态分生孢子，但各单孢培养系在致病力上无差异。

Since curly leaf hybrid could be recognized at early stage,and displayedobvious dwarfness,choosing"Zha′ai 76"as paternal parent not only raised thehybrid-selecting efficiency from the pollinated progenies,but also raised thebreeding efficiency of apomctc dwarf roostock of apple.

鉴别宽叶型杂种较难、需时较长(2-3年生时)并需与染色体倍性鉴定法相结合，因其形态变化较小而生长势又与平邑甜茶无融合生殖苗无明显差异；鉴别光叶型杂种因父本染色体组的影响加大而从形态上容易些，但也需过氧化物同工酶法或染色体倍性鉴定法相配合；皱叶型杂种因在苗期刚出1-2片真叶时就表现明显的标志性状、能从叶片形态上准确鉴别出来，毋须染色体倍性鉴定等复杂方法；因皱叶型杂种能早期鉴别，又表现明显的矮生性，因而选用"扎矮76"做父本不仅大大提高了平邑甜茶授粉后代中选择杂种的效率，而且提高了苹果无融合生殖型实生矮砧育种的效率。

The basic theories of mathematical morphology for binary image are stated, and the most simple structure elements of morphologic transformation for binary images are proposed and proved. The geodetic morphologic transformation models are also developed. For the purpose of improving the speed of transformation in computer, the"set symmetric difference"is introduced to adapt each model. Some new morphologic filtering models and quantitative evaluating model of filtering effects in image processing are proposed, under the applied condition. The morphologic thinning methods are studied, and two new morphologic thinning models are developed. On the basis of analyzing the characteristics of mining maps, the image vectorizing tactics and a series of algorithms are proposed, including dynamic adaptive image thresholding using two thresholds, graphic and text separation, noise removal, and multi elements extracting models with mathematical morphology. Accuracy preserving compressed vectorizing model for image vectorization is put forward to generate vector data in multi layer.

It is suggested that the product of tapetum degeneration may be absorbed by developing pollen. The special ultrastructural pattern at aperture of pollen represent a morphological adaptation to this short—way transportation of nutrition from the tapetum to pollen.

研究证明在绒毡层的降解和花粉内贮藏物的增加之间存在相关性，这说明绒毡层的降解产物可能被正在发育的花粉所吸收，而天竺葵花粉营养细胞所具有的典型的传递细胞的特点是这种吸收活动在形态上的表现。

We studied the optimum medium and hormone combination of callus induction from cotyledons, subculture of callus, shoot regeneration from callus, shoot-extension induction, root induction and identified the chromosome number of the plantlet. The results showed that: MS+2,4-D 2.0mg/L+KT 0.5mg/L, MS＋2,4-D 2.5mg/L＋KT 0.5mg/L, MS+2,4-D 0+KT 1.0mg/L, MS+KT 0.5 mg/L and basal MS medium. One plantlet among twenty two was determined as a tetraploidy based on the plant morphology, observation of the leaf stoma and chromosome number of the root, other two plantlets represented morphological variation.

结果表明，诱导章丘大葱子叶产生愈伤组织、愈伤组织的继代培养、愈伤组织芽分化、芽点的伸长及诱导生根的最佳培养基及激素配比分别为：MS+2，4-D 2.0mg/L+KT 0.5mg/L、MS＋2，4-D 2.5mg/L＋KT 0.5mg/L、MS+2，4-D 0+KT 1.0mg/L、MS+KT 0.5mg/L和MS基本培养基；试管苗经驯化移栽后，共有22株成活，成活率为92%，对成活的再生植株进行形态学、叶片气孔及根尖染色体鉴定表明，共有3株发生变异，其中2株为外部形态上的变异，而另一株为染色体的加倍变异。

Latimera was not significant, even smaller than that among populations with in groups. The results were similar to thoses obtained from morphology and molecular phylogenetics. All data strongly supported that H. tientsinensis and H. latimera was the same species. The difference of males'infraorbital crest between H.

该结果与天津厚蟹和侧足厚蟹的形态学及分子系统学分析的结果一致，进一步表明天津厚蟹和侧足厚蟹应为同一个物种，至于雄性下眼缘隆脊在二者之间的差异应视为形态上的2种不同的表型。

The purposes of this study were to:(1) compare the reproductive success and morphological variables of Blue-tailed Bee-eaters between solitary and colonial breeders and among different sizes of colony, and (2) examine if the nest location vs. reproductive success of Blue-tailed Bee-eaters fits the centre- periphery model.
