The transport and distribution of JA and ABA in M. micromalus Makino and their relation to water in soil

Abstract

The transport and distribution of JA (jasmonic acid) and ABA (abscisic acid) in Malus micromalus Makino seedling and their responses to water in soil were studied by radioisotope technique. The results indicated that JA was transported mainly via the phloem from shoot to root and ABA mainly from root to shoot via xylem. The conclusion that both JA and ABA were sensitive to water deficiency can be drawn because their transport rates were increased with a decrease in soil moisture content.
