Boron deficiency in maize

Boron (B) deficiency depresses wheat, barley and triticale yield through male sterility. On the basis of field responses to B fertilization, maize (Zea mays L.) is affected by B deficiency in five continents. In a series of sand culture trials with maize subject to B0 (nil added B) and B20 (20 μM ad...

Tassels, silk and pollen of B0 plants contained only 3-4 mg B kg-1DW compared with twice or more B in these reproductive tissues in B20 plants.
