Boron in the plant


Boron deficiency


In most plants the mobility of boron is limited

♦ Deficiency is manifested in young parts first

Boron is required for cell division

♦ Deficiencies are expressed at the growing points of roots and shoots as well as flowers and fruits

♦ Terminal buds die back, internode lengths shorten

♦ New growth is stubby and distorted

♦ Roots become short and stubby with few root hairs

Boron is essential for structural integrity of cell walls

♦ Growth might become brittle

Boron is involved in reproduction processes

♦ Flowering and fruiting are greatly reduced and/or distorted
