The present investigation entitled “Effect of copper on morphological and biochemical characteristics of Populus deltoides (W. Bartram Ex. Marshall)” was carried under laboratory conditions during the period 2013-2014. The study comprised of eleven treatments viz., T1 (No copper), T2 (100 ppm Cu), T3 (200 ppm Cu), T4 (100 ppm Cu + M. anisopliae, 1x105 condia/ml), T5 (100 ppm Cu + M. anisopliae, 1x106 condia/ml), T6 (200 ppm Cu + M. anisopliae, 1x105 condia/ml), T7 (200 ppm Cu + M. anisopliae, 1x106 condia/ml), T8 (100 ppm Cu + B. bassiana, 1 x 105condia/ml), T9 (100 ppm Cu + B. bassiana, 1x106 condia/ml), T10 (200 ppm Cu + B. bassiana (1x105 condia/ml), T11 (200 ppm Cu + B. bassiana,1x106 condia/ml). Highest and lowest number of leaves per plant were recorded at treatment T5 (53) and T1 (33), respectively, maximum and minimum leaf area was at treatments T9 (0.16 m2) and T1 (0.08 m2), respectively, whereas, maximum plant height (1.76 m) was observed in treatment T5. The biomass of different plant parts of P. deltoids viz., roots, stem and leaves was statistically minimum at T1. Highest chlorophyll and ascorbic acid content was recorded atT9 i.e., 0.28 mg/g and 5.60 mg/g, respectively. Total sugar content varied from 0.88 mg/g (T1) to 1.53 mg/g (T5). Highest phenol content (1.24 mg/g) was observed at treatment T3. Copper content in root, stem and leaves of P. deltoids varied from 31.00(T1)-68.25 (T3) ppm, 10.75 (T1) - 44.25 (T3) and 6.50 -34.25 ppm in T1 and T3, respectively. Distribution of copper content in different parts of P.deltoides was in the order root>stem>leaves.
