| Abstract: |
| Using the petri dishes filter paper method, this paper examined the effects of Tessaratoma papillosa gland
secretions on seed germination and seedling growth of radish, mustard and rice. The results showed that the T. papillosa
gland secretions significantly inhibited seed germination and seedling growth of the three tested species, and the inhibitory
effects increased with concentration increasing. The effect of female bug's gland secretions was more pronounced than the
male's, and the inhibition on the root was more obvious than the stem. At the concentration of 7 滋L/mL, the inhibitory
effects of the male and female bug's gland secretions on germination ration of radish reached 43% and 53%, respectively.
At the concentration of 4 滋L/mL, the inhibitory effects of the male and female bug's gland secretions on germination ration
of mustard reached 47% and 55%, respectively. At the concentration of 5 L/mL, the inhibitory effects of the male and
female bug's gland secretions on germination ration of rice reached 12% and 15%, respectively. At higher concentrations
the tested species stopped in growth. The results of this study indicated the strong activity of T. papillosa scent gland
secretions against the root growth of plant seeds. |
