Yield per plant was mostlyaffected by panicle per plant in Sanya, and did by seed set in Changsha.

在三亚影响单株粒重的最大的因素是单株穗数，且是负向影响；而在长沙影响单株粒重的最大的因素是结实率。

For the first time, this study conducted a series of field sampling in multiple locations over several years and demonstrated that the B and Q biotypes first invade areas with high frequency of transport through human movement of plant materials, and then rapidly spread into surrounding areas and displace indigenous genotypes, and in parallel with displacement significant changes in sex ratio occurred in the mixed populations. Crossing experiments demonstrated that in the B. tabaci species complex there are many genetic groups that are completely or nearly completely isolated in reproduction. Apart from behavioural mechanisms, difference in host plant suitability and insecticide susceptibility between whitefly biotypes may also play important roles in the displacement of indigenous whiteflies by alien whiteflies in Zhejiang.

本研究首次以一个地理区域内广泛系统的野外调查数据证实，B型和Q型烟粉虱首先通过花卉苗木调运入侵交通较为发达的地区，然后迅速向周边扩张并取代土著烟粉虱，同时入侵取代过程伴随着混合种群中性比的变化；杂交试验证明烟粉虱复合种内存在多个生殖上隔离或基本隔离的遗传群；B型烟粉虱在浙江省内迅速取代土著烟粉虱，除行为机制外，生物型之间寄主适应性和药剂敏感性等方面的差异也可能在此过程中起着重要作用。

The cowpea number per pod, weight per pod, length per pod, number of inflorescence; and the height of main stem, number of branches and node of main stem at seedling-pulling at each single plant were investigated for the yield-calculating, and meanwhile, the analysis of relevant factor and path analysis of the component of yield/plant was conducted.

方法］定株调查每株美国无架豇豆的豆英数、英重、英长、花序数，拉秧时测定主茎高、分枝数及主茎节数，并计算单株产量，进行单株产量构成因素的相关分析和通径分析。

On the base of the constructing phylogenetic tree using PAUP 4.0, MP and NJ (neighbor-joining) trees of diverse pectate and pectin lyases showed that pectate lyases from plant, pectin lyases from fungi and pectate lyases from bateria belong to different groups, respectively. The pectate lyase A of Aspergillus nidulans is more closely related to plant pectate lyases than to pectin lyase from fungi and pectate lyases from bacteria. The pectin lyase from Pseudomonas syringae is more closely related to fungi pectin lyases than other lyases.

There are two types of coal formation: a local land accumulation in which the original substance of rotten plant material congregates in a peat bog where plants are growing; b distant land accumulation in which the original substance, which is from nearby areas or somewhere distant, of rotten plant coal congregates in a fresh water basin, lagoon, delta or lake through movements.

The high turbidity problem in water out of the cyclofloc always exist in Pech?-David water treatment plant at Toulouse in France. Compared with the other water treatment plant at Toulouse, the turbidity of Pech-David was 2.3NTU and was higher than that of Clairfont as 0.5NTU. Coagulation jar-tests with several coagulants and coagulation aids from Floerger and Ciba company were studied to solve this problem.

Aiming at the currently shortage of XML streams quality detecting, this paper proposes a new forecasting method of XML streams quality by least squares support vector machines, which is used the method of XML keys' vector matrix as windows, and vector product wavelet transform to multilevel decompose and refactor the XML streams series, that can fulfill real-time checking demand of XML quality, and ensure constraint, consist- ency and integrality. For even more adapting net load, it proposes a control strategy by weight and adaptive adjustment to ensure XML streams quality.
