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
