Abstract
The ammonia assimilation enzymes glutamate dehydrogenase, glutamine synthetase [glutamate-ammonia ligase] and glutamate synthase, together with glutamate oxaloacetate transaminase [aspartate aminotransferase] and glutamate pyruvate transaminase [alanine aminotransferase] were assayed in the topmost fully-expanded leaf of the hybrid BJ104 and its parents J104 and 5141A at intervals throughout the growth period. The ammonia assimilation enzymes varied markedly in activity during development, these trends differing among genotypes; the hybrid equalled or exceeded the better parent (J104) in ammonia assimilation enzyme activity. Activities of the transaminases, however, were only slightly higher in the hybrid than in the worse parent (5141A). From a survey of the literature, it is proposed that there can be no universal biochemical criterion of hybrid vigour, but that parents should be selected according to their rate limiting steps so as to produce complementation in the hybrid
