EFFECT OF ROOTSTOCK ON LONGEVITY AND FRUIT AND TREE CHARACTERISTICS OF PLUM
in HortScienceThe dwarfing characteristics of St. Julien and Pixy rootstocks as measured by shoot growth and trunk cross-sectional area (TCSA) was evident. Tree survival was significantly reduced after 3 years on Nemaguard and Pixy rootstocks. None of the elements measured by foliar nutrient analysis were below the minimum for plums; however, significant multiple regression equations for total shoot growth, TCSA, and survivability were evident with R2 of ≈0.30 in all three cases.
