The first study was with clones of Prunus subcordataBenth. on seedling roots of peach, myrobalan plum, Marianna plum, and P. americanaMarsh. After four years, trees on peach root were the largest and those of P. americanawere smallest; however after 10 years the trees on all of the plum stocks were larger than those on peach. Fruit yield per tree and yield efficiency after 10 years was somewhat better on peach and P. americanathan on myrobalan or Marianna roots.
The second study was with peach cultivars on rootstocks of peach and several types of plum, with interstems of P. subcordataclones and of Yellow Kroos plum. Tree size was largest with peach and St. Julien A roots and smallest with P. tomentosaThunb. and Myrobalan B plum. Tree size as related to P. subcordatainterstems was largest with LIX clone and smallest with K-I clone. Yield efficiency was highest for peach and P. amercanarootstocks and lowest for Myrobalan B. Mineral nutrient content of peach leaves was generally high with peach and St. Julien A stocks and notably low with Marianna.
