Morphological, growth, and photosynthetic responses of cottonwood hybrid 47-174 (Populus trichocarpa x P. deltoides) to nitrogen fertilization and leaf rust infection
The growth, morphological, and photosynthetic responses of cottonwood hybrid 47-174 to nitrogen (N) stress and leaf rust stress and their interaction are summarized herein. High nitrogen (HN) fertilization enhanced growth and photosynthesis as compared to low nitrogen (LN). HN plants developed more and larger leaves, were ...
