水稻花粉悬浮培养及其在育种上的应用

评估了２０个水稻品种离体花粉悬浮培养产生愈伤组织和再分化植株的能力，并进行了花粉悬浮培养试验，结果表明；品种之间反应差异很大。来源于日本的“黎明”（粳稻）最敏感。“黎明”植株再分化的频率达８４．１％。在愈伤组织的形成和植株再分化过程中，除其它一些因子外，基因型的差异有一定制约作用。通过水稻花粉悬浮培养诱导出的新品系“Ｎ１０”，其特征有：早熟，穗大，株高（９０～１００ｃｍ），产量高和抗稻瘟病等。

On the Foundations of Constructive Mathematics – Especially in Relation to the Theory of Continuous Functions

We discuss the foundations of constructive mathematics, including recursive mathematics and intuitionism, in relation to classical mathematics. There are connections with the foundations of physics, due to the way in which the different branches of mathematics reflect reality. Many different axioms and their interrelationship are discussed. We show that there is a fundamental problem in BISH (Bishop’s school of constructive mathematics) with regard to its current definition of ‘continuous function’. This problem is closely related to the definition in BISH of ‘locally compact’. Possible approaches to this problem are discussed. Topology seems to be a key to understanding many issues. We offer several new simplifying axioms, which can form bridges between the various branches of constructive mathematics and classical mathematics (‘reuniting the antipodes’). We give a simplification of basic intuitionistic theory, especially with regard to so-called ‘bar induction’. We then plead for a limited number of axiomatic systems, which differentiate between the various branches of mathematics. Finally, in the appendix we offer BISH an elegant topological definition of ‘locally compact’, which unlike the current definition is equivalent to the usual classical and/or intuitionistic definition in classical and intuitionistic mathematics, respectively.
