摘要：

The effect of crude volatile oils extracted from the young leaves of Lantana camara var. camara was studied on the parent plant itself The contents of water and chlorophyll, of leaves apart from seed gemination, seed vigour and length of seedlings of the parent plant were adversely affected with increasing concentration of the Lantana oils; this indicated autotoxic potential of the oil The correlations between oil concentration and the studied parameters were rather strong and obeyed the concentration response relationship, typical of chemical bases The cell respiration, however, increased with increasing concentration of the oil vapours. Compared to control, less than 13 % of the seeds of the parent plant exposed to 30 cm 3 m-3 of oil showed incipient germination with no growth of radicle beyond unmeasurable protuberance, and no plumule emergence.
