Báo cáo khoa học: "Effects of irrigation and nitrogen fertiliser on the growth and nutrient relations of Prunus avium L and ’Colt’ (Prunus avium x Prunus pseudocerasus) in the nursery and after transplantation" Original article Effects of irrigation and nitrogen fertiliser on the growth and nutrient relations of Prunus avium L and ’Colt’ (Prunus avium x Prunus pseudocerasus) in the nursery and after transplantation NA TJ Samuelson Hipps, KH Higgs, LG Collard, Horticulture Research International, Perennial Crops Department, East Malling, Kent ME19 6BJ, UK January 1993; accepted 8 June 1994) 18 (ReceivedSummary —One—year—old seedlings of Prunus avium and hardwood cuttings of ’Colt’ were lined outand nitrogen fertiliser was applied at rates of between 0 and 9 g per tree either with or without irriga-tion. Nitrogen fertiliser had no effect on the growth and leaf mineral concentrations of either geno-type. Irrigation increased the growth of both genotypes and the concentrations of P and K in the leavesbut the concentrations of Mg and Ca were reduced. The following year the trees were lifted andreplanted. The plants of ’Colt’ that had previously received irrigation produced longer total shootlengths than unirrigated plants, whereas there was no difference for P avium. The residual effect of irri-gation slightly reduced the concentration of P in the leaves of both genotypes, yet the concentrationsof N, K, Ca, Mg and Mn were unaffected.Prunus I nutrition I nursery I transplant I growthRésumé — Effets de l’irrigation et de la fertilisation azotée sur la croissance et la nutrition dePrunus avium et de «Colt» (Prunus avium x Prunus pseudocerasus) en pépinière et aprèstransplantation. De jeunes semis de1 an de Prunus avium et des boutures ligneuses du cultivar«Colt» (Prunus avium X Prunus pseudocerasus) ont été plantés en ligne avec un faible espacement(0,3 m). Un engrais azoté a été appliqué à des niveaux variant de 0 à 9 g par arbre, avec ou sans irri-gation. Pour les 2 types de Prunus, la fertilisation azotée n’a pas eu d’effet, ni sur la croissance, ni surla concentration en éléments minéraux dans les feuilles. L’irrigation a augmenté la croissance et lesconcentrations en P et K dans les feuilles chez les 2 types de Prunus. En revanche, les concentrationsen Mg et Ca ont été réduites. L’année suivante, les arbres ont été amachés et transplantés. Les plantsde «Colt» qui avaient été précédemment irrigués ont produit alors une longueur totale de pousse plusimportante que les plants non irrigués. Au contraire, pour Prunus avium, aucune différence n’est appa-rue. L’effet résiduel de l’irrigation a consisté en une réduction de la concentration en P dans les feuillespour les 2 types de Prunus, alors que les concentrations en N, K, Ca, Mg et Mn n’étaient pas affectées.Prunus / nutrition / pépinière / transplantation / croissanceINTRODUCTION Thisreport investigates the interaction nitrogen fertiliser and irrigation on the of growth and nutrient relations of cherryNearly 90% of the UK’s consumption of for- seedlings and cuttings in the liner nursery products is imported (Forest Industryest and the subsquent performance after trans-Committee of Great Britain, 1987) and there plantation.is increased interest in the use of broadleaftrees as an alternative crop in lowland areaspreviously used for agriculture.
