| Abstract: |
| Solanum rostratum is a invasive weed, while tomato is a main local cultivated crop. We used the filter paper method in petri dish under variable temperature in illumination box to study the effects of the root, stem and leaf extract of Solanum rostratum on seed germination rate, germination speed, root length and seedling height of tomato. The results showed that:(1)The extract of different organs of Solanum rostratum had different effects on seed germination rate, germination speed, root length and seedling height of tomato, among which the allelopathy effects of the extract of stem and leaf were more significant(P<0.01). (2)The extract of the same organ of Solanum rostratum had different effects on seed germination rate, germination speed, root length and seeding height of tomato. The effeet of root extract was
not significant(P>0.05)for the seed germination rate and root length of tomato, but the effect was more significant on
germination speed(P<0.01). The effect of the extract of stem and leaf of Solanum rostratum on germination
speed was the most significant(P<0.01). |
