Корни, как и все другие органы растения, дышат. При дыхании клетки корня поглощают кислород и выделяют углекислый газ. ... Выращивая растения, надо следить, чтобы к корням постоянно поступал свежий воздух. Для этого почву регулярно рыхлят культиваторами или мотыгами.
Для нормального роста и развития растения необходимо, чтобы к его корням поступал свежий воздух. В этом можно убедиться на несложном опыте.
Возьмем два одинаковых сосуда с водой, в которой растворены все необходимые минеральные вещества. В каждый сосуд поместим по два одинаково развивающихся проростка фасоли или подсолнечника. Воду в одном из сосудов ежедневно будем насыщать воздухом с пульверизатора. На поверхность воды во втором сосуде нальем тонкий слой растительного масла. Масло задерживает поступление воздуха в воду. Через некоторое время растения во втором сосуде перестанут расти, зачахнут и в конце концов погибнут. Гибель растений наступает из-за недостатка воздуха, необходимого для дыхания корней.
