葡萄属(Vitis)种间杂交一代(F_1)果实抗白粉病的遗传

通过对７个欧洲葡萄品种与４个中国葡萄野生种组成的１１个杂交组合的果实抗白粉病田间自然发病调查，结果表明，后代群体的抗病性呈连续性分布，表现出多基因遗传的特征。在供试的中国葡萄资源中，华东葡萄、毛葡萄和秋葡萄具有将其抗性遗传给后代（Ｆ１）的较强能力。     

Inheritance hierarchy design in object-oriented databases

Object-oriented database schema design is still mostly an art. One of the difficulties encountered during design is typing conflicts induced by multiple inheritance. In this paper, we propose a method for treating such a kind of conflicts. Our approach to inheritance conflict solving consists of several ingredients. First, we rely on branding, to introduce ‘type equivalence by name', thus allowing a designer to distinguish between structurally similar but semantically different types. However, we offer a heuristic that does not require a designer to explicitly state branding declarations. Second, we describe various kinds of conflicts, and we offer a set of procedures that analyze a schema to discover such conflicts, classify them, offering potential solutions, if possible. The procedures have been conceived for a design system that allows a designer maximum flexibility, while guiding him/her to a correct design.

A comparison of object-oriented programming in four modern languages

Object-oriented programming has become a widely used, important programming paradigm that is supported in many different languages. C++ has become the most widely used object-oriented language and many C++ programmers are unfamiliar with the different approaches taken by other languages in the paradigm. This paper is intended as an introduction to a broad range of ideas in object-oriented programming. Specifically, we introduce four modern programming languages that support object-oriented programming (Oberon-2, Modula-3, Sather and Self), and show how a simple application is coded in these languages. While each of these programming languages provide support for inheritance, dynamic dispatch, code reuse, and information hiding, they do so in very different ways and with varying levels of efficiency and simplicity. The use of a simple example, based on a common programming problem, facilitates our comparison. We have coded the application in all of these languages, including C++, and we compare the compile times, object code sizes, and run times of the available implementations. Implementations of all the languages compared and all of the programs we measure are available on the Internet. Ultimately, our goal is to encourage and facilitate programmers in understanding and exploring a variety of object-oriented programming languages.

Arbutin in marjoram and oregano

Arbutin is a hydroquinone derivative that has been found in species of several plant families. Within the genus Origanum the formation of arbutin is polymorphic, with arbutin present in considerable amounts (O. dubium 20.8 ± 15.3 mg/g; wild O. majorana 51.3 ± 15.4 mg/g, cultivated O. majorana 40.6 ± 11.2 mg/g), minor amounts (O. microphyllum 0.1 ± 0.1 mg/g, wild O. onites 0.3 ± 0.1 mg/g, cultivated O. onites 0.1 ± 0.1 mg/g, O. saccatum 0.1 ± 0.1 mg/g, O. solymicum 0.4 ± 1.0 mg/g) or completely absent (O. husnucan-baseri, O. syriacum, O. vulgare). Whereas the most important commercial oregano species (O. onites and O. vulgare) contain no or only minor amounts of arbutin, marjoram (O. majorana) has considerably high amounts. The high variability of arbutin in O. majorana would allow a selection into cultivars with high arbutin content and low arbutin varieties. In a segregating F₂-generation of a species crossing between O. majorana (high content of arbutin) and O. vulgare ssp. vulgare (free of arbutin), the presence of arbutin followed a Mendelian segregation of 3:1, indicating that only one gene is responsible for the polymorphism of arbutin in the genus Origanum. The absence of arbutin in O. vulgare ssp. vulgare or O. syriacum would even enable the breeding of marjoram with no arbutin at all.
