GLUCOSINOLATE CONTENT OF MATURING PODS AND SEEDS OF HIGH AND LOW GLUCOSINOLATE SUMMER RAPE

Abstract

3-Butenyl-, 4-pentenyl-, 2-hydroxy-3-butenyl- and 4-hydroxy-3-indolylmethylglucosinolate were found to be major glucosinolates in developing pod tissue and seed of both high and low glucosinolate lines of rapeseed. These glucosinolate profiles along with decreases in the glucosinolate content of pod tissue over a period of 18 d after pollination, and increases in the seed, were consistent with the pod tissue being a source of glucosinolate accumulating in the seed.Key words: Rapeseed, Brassica napus L., Cruciferae, glucosinolate, seed development
