abscisovou

Abscisovou is a grammatical form in Czech, specifically the instrumental singular feminine form of the adjective abscisová. The base adjective abscisová describes something relating to abscisic acid, a plant hormone, and is commonly used with feminine nouns such as kyselina (acid). The form abscisovou appears in contexts where the feminine noun is in the instrumental case, for example after the preposition s or in constructions requiring the instrumental, or as the attributive adjective before a feminine noun in other cases, such as abscisovou kyselinou or abscisovou kyselinu.

In practice, abscisovou occurs most often in scientific or technical Czech when referring to abscisic acid. Abscisic acid itself, known in Czech as kyselina abscisová, is a phytohormone involved in processes such as stress responses, seed dormancy, and stomatal regulation. The name abscisová derives from the term abscission, the natural shedding of leaves, fruits, or other plant parts, reflecting historical observations related to the hormone’s effects.

Etymologically, the word abscisová and its inflected forms trace back to the term abscisic acid, adapted into Czech scientific vocabulary. As a grammatical item, abscisovou does not denote a separate concept but rather a surface form used to modify feminine nouns in the instrumental case. Its use is governed by standard Czech declension rules for adjectives ending in -ová.
