Boron deficiency on citrus-Citrus

Symptoms
Boron deficiency causes the death of the terminal growing point. The tree loses its apical dominance and sends out multiple shoots.

Reasons
Boron deficiency on shoots

Symptoms
Early breakdown of albedo, caused by poor boron supply. Gum spots in the albedo of the fruit and flesh near the rind may occur and result in fruit creasing (shrivelled surface makes processing more difficult).

Reasons
Boron deficiency Poor boron supply reduces calcium uptake and therefore can induce a breakdown of the albedo and promote post-harvest rot.

Symptoms
Boron deficiency causes the death of the terminal growing point. The tree loses its apical dominance and sends out multiple shoots.

Reasons
Boron deficiency on shoots

Symptoms
A lack of boron results in gum pockets forming in the fruit albedo and flesh, near the rind. Fruit is small and hard with gum like spots appering on the skin.

Reasons
Boron deficiency Citrus is sensitive to boron. Poor boron supply reduces calcium uptake and therefore can induce a breakdown of the albedo and promote post-harvest rot.
