Fertility level affects apple rootstock structure and root:shoot ratio

One-year old seedlings of Malus hupehensis ‘Pingyitiancha’, M. micromalus ‘Balenghaitang’, and M. micromalus ‘Laiwunanyan’, were evaluated under different fertilizer levels to determine the effect of fertility level on root system structure and root:shoot ratio. Root system area decreased as fertili...

Summary:One-year old seedlings of Malus hupehensis ‘Pingyitiancha’, M. micromalus ‘Balenghaitang’, and M. micromalus ‘Laiwunanyan’, were evaluated under different fertilizer levels to determine the effect of fertility level on root system structure and root:shoot ratio. Root system area decreased as fertility level increased. Root:shoot ratio decreased as soil fertility increased. The decrease in the ratio was different for the different species with ‘Pingyitiancha’ apple rootstocks being more affected than ‘Balenghaitang’ and ‘Laiwunanyan’ rootstocks. There was a significant correlations between root:shoot ratio and water use efficiency (WUE).
