title: BORON AS A GROWTH REQUIREMENT FOR DIATOMS(1).
abstract: A boron requirement has been shown for 12 species of marine pennate diatoms, 4 species of marine centric diatoms, and S freshwater diatom species. It can be concluded that boron is essential for the growth of most, probably all, diatoms. It is much easier to demonstrate a requirement for the marine species than for the freshwater species. Some species of marine algal flagellates also require boron for growth; others apparently do not.
