| 摘 要： | 研究了白花曼陀罗(D a tura m etel L inn.)叶提取物对南方根结线虫(M eloid ogyne incogn ita Ch it-w ood.)生长发育的影响。结果表明,白花曼陀罗叶提取物对南方根结线虫胚胎发育和胚后发育有抑制作用。1%白花曼陀罗叶提取物处理48 h,仅有19.88%的卵完成胚胎发育,且变异卵增多;胚后发育历程、初侵染、初产卵日分别推迟2、4、6 d,雌虫产卵量降低。 |
| 关 键 词： | 白花曼陀罗 叶提取物 南方根结线虫 胚胎发育 胚后发育 |

| Abstract: | Effect of the extract from the leaf of Datura metel Linn.on development of Meloidogyne incognita Chitwood.was studied.The results showed that extract could significantly inhibit embryonic and post-embryonic development of nematode.With 1%(W/V) of extract to treat for 48 h,only 19.88% eggs had completed their embryonic development and the abnormal eggs increased;The postembryonic development,juvenile penetration,female reproduction were delayed 2,4,6 days,respectively,and the amount of eggs of female reduced. |
| Keywords: | Datura metel Linn extract of leaf Meloidogyne incognita Chitwood embryonic development post-embryonic development |
