Abstract
Nitrogen fertility levels during the summer and fall had little effect on cold acclimation of root or stem tissues of container-grown plants of Forsythia intermedia Zab. cv. Lynwood by mid-November 1969. Tissue N levels of roots decreased from August 1 to September 3, but had increased again on October 30. Nitrogen fertilization rates affected tissue levels of P and K in Forsythia roots. Nitrogen and P levels that resulted in acceptable plants had limited effect on cold acclimation of Cornus alba L. var. sibirica Loud and Forsythia roots and stems in late October or early November 1970. Increased N and P fertilization affected tissue levels of N, P, K, Ca, and Mg.Keywords
