New Methods for Effecting Watertight Seals on Corn Roots

Abstract

A sealing compound (anhydrous lanolin containing 5% paraffin) may be applied melted (MP 38-42[degree]C) or compressed cold into the interstices about a corn root inserted into a glass capillary. These seals are capable of withstanding 15 cm and 2 m of hydrostatic pressure respectively. Neither seal alters the root''s normal growth pattern, absorption-transport capacity, or microscopic appearance.
