Multi-elemental isotope and analog tracer application to measure nutrient uptake and distribution in Malus domestica Borkh.

This study uses isotopically labeled nutrients and analogs to measure uptake and distribution in apple cultivars, finding differences in tracer recovery rates and genotype-specific nutrient absorption.

Variation in scion water relations mediated by two newly released Geneva series rootstocks

This study compares the effects of three apple rootstocks on scion physiological traits, finding that rootstock-induced vigor correlates with stomatal conductance, stem water potential, and isotope composition.

Timing of water limitations affects source to sink differences in δ13C composition in apple

This study shows that sink tissues, not leaves, are more sensitive to in-season water deficits, making carbon isotope composition a useful proxy for assessing deficit irrigation effectiveness.

Climate change and chill accumulation: implications for tree fruit production in cold-winter regions

The paper quantifies how climate change may affect chill accumulation in the Pacific Northwest, identifying spatial and temporal variations and potential risks for tree fruit production.
