摘要: One of the most important soilborne diseases affecting avocado (Persea americana Mill.) crops is white root rot, caused by fungus Rosellinia necatrix. In this study we investigated metabolic responses elicited rot in aerial part plant with special focus on potential applications imaging technique (including chlorophyll fluorescence (Chl-F), blue-green and thermography) early detection disease leaves. The results show that leaf metabolism was significantly affected infection only when symptoms started to appear, which probably related loss functionality. However, changes some Chl-F parameters provided indications stress even prior development symptoms. We suggest combinatorial analysis several could be used as a method for might prove useful general indicator biotic abiotic plants.
