Abstract
Toxic effert of water extract from leaves of Pinus rigida and some phenolic compounds on the seeds germination of Raphanus sativus var. hortensis for. acanthiformis Makino has been studied. There was little difference of germination percentage among the pH value of leaf extract (pH3~9). The germination percentage drastically with increased concentration level of leaf extract at about 60 percent. Seeds gemination of Raphanus sativus var. hortensis for. acanthiformis Makino inhibited severely by caffeic acid, ferulic acid and p-coumaric acid at M, but the germination percentage was higher than that of the control group in vanillic acid. In electrophoresis, there was no differences at earlier seedling stage of protein band between allelochemical treated and non-treated group, but in late stage, two protein band near 58kd and 27kd did not appeared in the toxic affected group. In case of caffeic acid treatment, two protein band near 58kd and 27kd did not found at late stage too.
