Free amino acids in 6-year Kiwifruit vines[Actinidia deliciosa (A.Chev.) C.F. Liang et A.R. Ferguson] were measured over the course of wholevne harvests. Tissues examined from the perennial structure consisted of the wood and cortex of structural roots. wood and bark of stem. Leader and 1-wear old fruiting canes. Free acids in the annual growth (fines roots, flowers, fruit, leaves and non-fruiting shoots) were also measured. The range of amino acids extracted indicated that kiwifruti conforms to a conventional pattern of nitrogen metabolism. Acids present in greatest concentration depended on tissue type and sampling time.In perennial components and fine roots, arginine and glutanmine were the predominat species, followed by gamma-aminobutyrate, aspartateglutamate, alamine and valine. Generally, maximum concentrations of all free acids were measured in a 10-weed period around budbreak. These same acids plus asparagine, serine and threonine, were also prevalent in annual growth. In leaves, flowers and non-fruiting shoots, concentrations were greatest in the young tissue and declined with age. By contrast, concentrations of arginine, asparagine and gutamine in fruit peaked aproximately 10 weeks after anthesis subsequent to the cell division phase of growth. During the year, free arginine averaged 44, 48 znc 58% of the total N inteh fine roots, and the cortex and wood of structural roots, respectively (the quantity of total N and amino-N in other components of the structural framework was much less than that...
