Studies on Lateral Movement of Phosphorus 32 in Peppermint.

Auchter (1) wras the first to show that very little lateral nmovemiient of nutrient elemiients occurred in certain plants. The work of Caldwell (3) and McAMurtrey (7) also indicate(d a lack of lateral movemleint of mineral elements in the test plants used. From these studies, it seenms that there is a lack of lateral nmovement of nmineral nutrients in some plants. It was (lecidedl to test this i(lea using the radioactive elemlient P32, in peppernmint (Mctitlia piperita L.) plants. The purpose of this study was to investigate, using a split root technique andl P322 the type of movement
