Effect of Nitrogen Deficiency and Fusarium Graminearum Infection on Relative Chlorophyll Content of Maize Seedlings

Nowadays the global climate change significantly affects agricultural production due to different biotic and abiotic stresses. Phythopathogens, like fusarium, can cause serious injury which could be worsened by climatic conditions. The goal of our experiment was examine single combined effect nitrogen (N) deprivation Fusarium graminearum infection on physiology some maize genotypes. Furthermore, we would know impact mentioned factors rate remobilization relative chlorophyll content (SPAD value) leaves with ages. Controlled pot set up in a room, (Zea mays L.) genotypes were grown using hydroponic Inoculation conidia performed as stress at 5-leaf (V5) stage seedlings two N level used during experiment: optimal quarter it from beginning. Our results suggest that influenced SPAD values regardless age genotype. Strong interaction found between case younger leaves. In these decreased inoculation, but just level.
