摘要：

The production of grafted seedlings of pear and peach trees in hydroponics is recent and has been becoming a promising propagation method with a significant reduction in the seedling production time. This study was conducted in order to determine the dry matter of plant parts and the accumulation of macro and micronutrients by pear grafted seedlings in hydroponic conditions. It was used a completely randomized factorial scheme 3 x 3 with four replications was. Each replication was made up of two plants (one in each tube), amounting to 72 plants. The factors under study were: three cultivars (Triunfo, Tenra and Cascatense) and three sorts of grafting (bench grafting -BP, inverted T budding -BT and cleft grafting -GF). The nutrient accumulation in pear seedlings, regardless of the cultivar, settled in the following order for macronutrients: N>Mg>K>Ca>P>S; and micronutrients: Fe>Mn>B>Zn>Cu.
