| 采用培养皿滤纸法研究了荔枝蝽雌雄成虫臭腺分泌物对萝卜Raphanus sativus芥菜Brassica juncea
和水稻Oryza sativa种子萌发及幼苗生长的影响，结果表明，荔枝蝽臭腺分泌物对3 种植物种子萌发和生长都有明
显的抑制作用且随着浓度的增大抑制作用增强雌成虫臭腺分泌物的抑制作用比雄成虫更显著且雌雄成虫臭腺
分泌物对根的抑制作用均比对茎的抑制作用强，雌雄成虫臭腺分泌物浓度为7 L/mL 时对萝卜种子萌发的抑制率
分别为53%和43%;雌雄成虫臭腺分泌物浓度为4 L/mL 时对芥菜种子萌发的抑制率分别为55%和47%;而雌雄成
虫臭腺分泌物浓度为5 L/mL 时对水稻种子萌发的抑制率分别为15%和12%且高浓度时种子不萌发。结果表明，
荔枝蝽臭腺分泌物对植物种子根系的生长具有较强的活性作用。 |
| 英文摘要: |
| 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. |
