of inhibition of the compounds on four growth parameters of banyardgrass
and hemp sesbania.
Total fresh weight
Values followed by an asterisk are
significantly different from the control at the 0.05 level according to
general linear model procedure.
In a study (Shilling et al., 1987), the
toxicity to terresterial plants was evaluated. The observations were the
0% of inhibition is observed for all growth parameter followed when
seeds are exposed to ethyl vanillin at 2 mM during 60h. In the test
conditions, Ethylvanillin as no phytotoxic effect on this species.
Only a slight inhibition (between 15 and 19%) on growth parameters has
been observed after 72h of exposition of ethylvanillin at 2 mM. But it
is significantly different from the controls only for 1 of the 3 growth
parameters (total fresh weight) but not for the most sensitive one the
Only the total fresh weight is significantly
different from the control. The two other parameters measured (root and
shoot lengths) are not significantly different from the control. It is
may be due to the difficulty on measuring these parameters. But authors
also indicate that root growth was the most sensitive parameter and
total fresh weight even if easier to measure is less sensitive. As Ethyl
vanillin showed an effect only on the less sensitive growth parameter,
and not on the two other more sensitive ones, it is therefore
reasonnable to assess that Ethyl vanillin as no phytotoxic effect on
this species in the described conditions.
