Accepted Answer

Перевод задания: На какой важной стадии роста пшеница обычно наиболее чувствительна к сильному водному стрессу или засухе?

A) Flowering and grain-filling (anthesis). Water stress around flowering can reduce grain set, and stress during grain filling can limit grain development and yield.

Перевод: A) Цветение и налив зерна (антезис). Недостаток воды во время цветения может уменьшить количество завязавшихся зёрен, а стресс при наливе зерна — ограничить развитие зерна и снизить урожайность.
