… This study explains the mechanism that caused inhibition of AR formation in apple rootstock
under a high nitrate supply. Root morphological parameters were measures significantly …

… by the high nitrate … of high nitrate on ARs formation in B9 apple rootstock. This study also
exposes the complex hormonal and miRNA mediated inhibitory networks involved in high nitrate…

… or nitrate. With MM. 106 and M.26 rootstocks, fruit from the trees fed with nitrate nitrogen
were larger, had better surface color, higher soluble solids, higher levels of sugars, and higher …

… .1, is inhibited by high nitrate concentrations and activated by low nitrate concentration.
Additionally, the transcript of MdNRT2.1 was observed higher in response to control nursery …

… C assimilation in the apple rootstock M26 seedlings under normal (5 mM NO 3 -, NN) and
high (30 mM NO 3 -, HN) NO 3 - concentrations. Our results showed that high NO 3 - supply …

… −1 ) in leaves is important for developing desired apple rootstocks. Collectively, our data
revealed that lower-N plus optimal Ca and higher-N plus more Ca could ensure better growth …

… of nitrate-mediated ARs remain to be explored in apple. In this study, stem cuttings of B9 apple
rootstocks were treated with different nitrate … , MdANR1 expression was higher at 3 days, 7 …

… B9 apple rootstock is commonly used for apple cultivation. The tree architecture is vigorous,
resistant to environmental stresses, higher … nitrate levels whereas, suppressed at high nitrate …

… led to a higher nitrate absorption capacity. Meanwhile, a higher net NO 3 – influx rate under
6 mM K + treatment also implied that a moderate K supply level will promote nitrate ions into …

… is sufficient, the NO 3 - concentration was lower in leaves than roots, which might be
related to higher nitrate reduction and utilization. The amino acid compounds concentration in …
