Abstract

Leaf and bark aqueous extracts of Anthocephallus chinensis, Albizzia procera and Aporosa octandra were tested on crops viz. Oryza sativa, Glycine max and Brassica campestris for phytotoxic effects on germination and radicle length. Leaf and bark extracts of trees inhibited the germination and radicle length of all crops except G. max for radicle length in bark aqueous extract of A. chinensis, which stimulated to the extent of 30.03% over control. The lowest germination of crops (irrespective of trees and source of extracts) was for B. campestris (55 %) followed by O. sativa (82.5%) and G. max (84.5%). Similarly, like germination, maximum growth of radicle was for G. max (8.42 cm) followed by O. sativa (4.72 cm) and B. campestris (2.95 cm). Thus, in order of toxicity of trees (irrespective of crops) were Aporosa octandra > Albizzia procera > Anthocephallus chinensis. However, the tolerance in crops was in order of (irrespective trees and source of extract) G. max > O. sativa > B. campestris.
