Taking the advantage of microsatellite marker in individual identification, plan to verificate the blades of pure line on molecular level.

在海上培养的纯系丝状体后代叶状体在产量和质量上比同一海区养殖的普通种类具有优势。

Leaves apparently alternate, distichous; nanophylls present or absent, opposite to normal leaves; stipules 2; leaf blade 3-veined, one major lateral vein sometimes inserted above the base, or pinnately veined, base asymmetric, margin entire or serrate; cystoliths mostly present, linear or fusiform.

叶表面上互生，2列；微形叶宿存或无，对生于正常的叶；托叶2；叶片3脉，主要的一侧脉高于那些基部，或成羽状脉，基部不对称，边缘全缘或有锯齿；乳状体多数宿存，线或者纺锤形。

Samples of conchocelis and gametophytic baldes of both SF-1 and Y-6 (isolated from SF-1 line) lines had a unique allele on PC40 locus, indicating that it can be used as a marker to distinguish these two lines from the others.

在引物PC-40界定的遗传座位上，2个优良品系申福1号和优质6号（以申福1号为母本选育出来的品系）的丝状体和叶状体均出现了区别于其他品系的等位基因，显示对这2个优良品系进行SSR特异性标记是可能的。

60Co-γray was a useful mutagen in induced mutation breeding .After treated with 60Co-γray ,free-living conchocelis of wild Porphyra haitanensis were induced and represented in offsprings. Purple mutant and excellent practical characters strains were selected from a lot of gametophytic blades. Single cell clone and enzymolysis were used to propagate fast in pure strains of induced mutations.

坛紫菜野生丝状体经一定剂量60Co-γ射线辐照后，子代叶状体发生了变异，经大量培养后筛选出紫色突变体（3号Ⅰ）和经济性状优良的个体（7号Ⅰ和7号Ⅱ），通过体细胞酶解和单克隆技术快速获得诱变选育纯系，并对其主要经济性状进行了研究。

The leaflike thalli of certain algae and lichens may also be termed fronds.

某些藻类和地衣的叶状结构可称为叶状体，参见 megaphyll。

Type genus of Sphaerocarpaceae; liverworts with small many-lobed usually orbicular thallus.

球蒴苔科的模式属；地钱，具有小的多数情况下呈叶状环形叶状体。

The young prothalli are asymmetric and the mature are cordate and naked.

幼原叶体不对称，成熟原叶体裸露，无毛状体，呈心脏形。

These were raised underinducing condition to test if any morphology and structure changes. Twenty two Arabidopsismutants had various changes in morphology and anatomical structures. Twenty mutants hadlow germination rate from 10% to 60%, of which 2 had survival rates at 0% and 50%. Fivemutants occurred structure changes in the hypocotyls or stem. One of these lines, namedarris-stem, showed some unique changes: slower growth rate in comparison with the wildtype from germination to florescence; serrated margin of leaf blades, spiral rosette; morebranch in the bottom part of the stem, shorter nodes, twisted stem and branch. There were oneor several arrises along the stem. Across sections of the arrises showed one or several compactcells lumps which were round, made up of several layers of cells, looked like vascular-bundle.

在诱导条件下，这些突变体表现出不同的形态和结构的变化，共有22个表型和结构发生变化。20个突变系发芽率或存活率较低，发芽率由10％—60％，其中2个突变系存活率分别为0％和50％。5个突变系在茎或下胚轴的结构上发生变化，其中一个突变系arris-stem发生如下表型变化：从真叶出现至开花结实的整个生长期，生长速度要明显比野生型拟南芥缓慢；叶缘有明显锯齿，莲座叶呈螺旋状排列；茎的基部有较多侧枝，侧枝间距明显缩短，茎有明显扭曲；突变体茎侧面有1至数条棱形突起，内部存在一至数个排列紧密的细胞团，由多层细胞呈环形排列，细胞壁明显加厚，内部存在管状分子，推测为维管组织。

The concept of equivalent rotationally rigidity is offered and the formula of rotationally rigidity is obtained.

主要做了如下几个方面的工作：对伸臂位于顶部的单层框架—筒体模型进行分析，提出了等效转动约束的概念和转动约束刚度的表达式。
