| Abstract: |
| The objective of the present study is to investigate the effects of cultivating transgenic herbicide-resistant corn CC-2, with the EPSPS gene, soil Collembola community. From May to October 2014, soil collembolans were extracted from both transgenic and control(Zheng 58) corn, using the Macfadyen method, and the community composition, morphology, and diversity of the samples were measured. Redundancy analysis was also used to investigate relationships between Collembola community and environmental factors of the soil. The composition and diversity(species richness, density, Simpson index, Shannon-Wiener diversity index, and Pieou index) of the Collembolan communities from the transgenic and control corn were similar, whereas the morphological characteristics(oceli number, body length, body pigmentation, furca development, and antenna length) of the communities were different, although not significantly(repeated measures ANOVA). Redundancy analysis indicated that corn root biomass and water content, but not corn variety, significantly affected Collembola community. The preliminary conclusion of the present study is that the cultivation of transgenic herbicide-resistant corn CC-2 has no adverse effect on soil Collembola community. |
