In this contribution the following aspects of the practical application of plant bioregulators have been discussed.--What are plant bioregulators from the practical point of view?--What influences are bioregulators supposed to exert on plant growth?--To what uses have bioregulators been put up to now in crop production? From the practical point of view, both endogenous and exogenous substances can be regarded as bioregulators if, in low concentrations and without having any biocidal or nutritive action, they exert an influence on the growth, development and composition of the plant. The bioregulators have been categorized according to their interactions with the five phytohormone groups and a survey is given of those known hitherto, supplemented by a list of further substances with different types of mechanism of action. For the practical use of plant bioregulators a concept of application is described which distinguished between a variant dealing with the botanical and physiological aspects and another with crop cultivation and economic aspects. The practical application of plant bioregulators as it stands at present is indicated by way of various examples. Solutions of decisive problems in the cultivation of crops have been achieved up to now, for example, by strengthening the stems of cereals with gibberellin antagonists and by inducing blossoming, ripening and abscission processes with ethylene generators.
在本论文中，讨论了植物生长调节剂实际应用的以下几个方面。——从实际角度来看，什么是植物生长调节剂？——生长调节剂对植物生长会产生哪些影响？——到目前为止，生长调节剂在作物生产中有哪些用途？从实际角度而言，如果内源和外源物质在低浓度下且无任何杀菌或营养作用时，能对植物的生长、发育和组成产生影响，那么它们都可被视为生长调节剂。已根据生长调节剂与五类植物激素的相互作用对其进行了分类，并对迄今已知的生长调节剂进行了综述，还补充了具有不同作用机制的其他物质清单。对于植物生长调节剂的实际应用，描述了一种应用概念，该概念区分了涉及植物学和生理学方面的变体以及涉及作物栽培和经济方面的变体。通过各种实例说明了目前植物生长调节剂的实际应用情况。例如，到目前为止，通过使用赤霉素拮抗剂增强谷物茎杆以及使用乙烯发生剂诱导开花、成熟和脱落过程，已经解决了作物栽培中的一些关键问题。
