Boreal forests receive nitrogen-(N)-enrichment via atmospheric deposition and industrial fertilization. While it is known that N-enrichment can intensify interactions with natural antagonists, it remains poorly understood how genetic variability in plant defense chemistry can affect biotic interactions and height growth in N-enriched environments. We grew replicates of five low- and high-tannin Populus tremula genotypes, respectively, under three N-treatments (ambient, 15, and 150 kg N ha−1 yr−1). We assessed shoot blight occurrence (i.e. symptoms caused by Venturia fungi) during four growing seasons, and tree height growth during the same period. Damage by Venturia spp. increased with N-addition during all years, likely …
Comparative Analysis Of The Relationship Between Morphological, Physiological, And Biochemical Properties In Spinach (Spinacea Oleracea L.) Under Deficit Irrigation Conditions, Musa Seymen
Turkish Journal of Agriculture and Forestry
Drought is an abiotic stress factor that negatively affects plant development and causes economic losses in plant production, and its effect is getting significant every day. Spinach contains a high amount of water and drought stress affects its development as well as causing changes in its biochemical contents. In this study, it is aimed to determine the changes in the morphological, physiological, and biochemical contents of spinach grown under deficit irrigation conditions in different stages of development. For this purpose, by considering five different irrigation levels (I100, I80, I60, I40, and I20), and 4 harvest times determined according to the …
