Sciences, University of Chit- ta.ong, Ba.gla.esh. Five econom.ca.ly im.orta.t a.ricul- tura. crops （Oryza.sa.iva.L., Triticum.a.stivum.L., Vigna.sinensis L., a.elm.schus esculentus L. a.d a.0}ra.thus tricolor L.） a.d three forest crops （a.a.ia.a.riculiform.s a.

Germ.na.ion percent of forest crops declined with increa.ing concentra.ion of extra.ts. The inhibitory effect on root elonga.ion of forest crops wa. pronounced, wherea. a.stim.la.ory effect wa. found on P. fa.ca.a.ia.up to a.concentra.ion of 25 %. a.elm.schus esculentus showed poor germ.na.ion （%） a.d low shoot developm.nt （0.5 cm. a.d no developm.nt of ta.root or la.era. roots a. trea.m.nt of 100 % concentra.ion. Theinhibitory effect wa. proportiona. to the concentra.ions of the extra.ts with higher concentra.ions producing stronger inhibitory effects. Lower concentra.ions showed som. stim.la.ory effect.

In this procedure, nonlinea. force-displa.em.nt or m.m.nt-curva.ure （m.φ） beha.ior needs to be defined. In the a.C-40 docum.nt, va.ues of m.φ ha.e been proposed to m.del elem.nts in a.nonlinea. procedure.
