Abstract

The objective of this work was to assess the photosynthetic efficiency of sugarcane crop, in pre-emergency application, of two herbicides inhibiting photosynthesis. For sugar cane cuttings planting (variety SP80-3280), pots with a capacity of 8 dm3 were used. Atrazine and tebuthiuron application was performed by using a stationary spray installed in laboratory conditions and after treatment application, plants were transported to a green house where were kept until the end of the trial.  The reading of transport rate (ETR) was conducted in the middle portion of the youngest leaves of sugarcane with a portable fluorometer, with intervals for ETR assessment constituted by: 16, 17, 19, 25 and 30 days after herbicide application. It was also realized visual analysis of phytotoxiciy performed 30 days after application. The results showed that tebuthiuron herbicide caused greater reduction in the rate of electron transport than atrazine. In relation to herbicide symptoms, there was no significant difference between the studied herbicides. At the end of the work it could be verified that the chosen method using fluorometer to measure the rate of electron transport after herbicide application was adequate, allowing verifying sugar cane crop intoxication, even before any visual detection of herbicides performance in plants.

苗期施用阿特拉津和丁硫脲对甘蔗电子传递速率的影响
本研究的目的是评估两种抑制光合作用的除草剂在应急前施用对甘蔗作物光合效率的影响。甘蔗扦插(品种SP80-3280)采用8 dm3盆栽。阿特拉津和丁硫脲的施用是通过在实验室条件下安装的固定喷雾器进行的,施用处理后,植物被运送到温室,在那里一直保存到试验结束。采用便携式荧光仪对甘蔗最年轻叶片中部进行转运率(ETR)测定,测定间隔时间为:施用除草剂后16、17、19、25和30 d。应用后30天还实现了植物毒性的目视分析。结果表明,丁硫脲除草剂比阿特拉津更能降低植物的电子传递速率。在除草剂症状方面,不同除草剂间无显著差异。在工作结束时,可以验证所选择的使用荧光计测量除草剂施用后电子传输速率的方法是适当的,甚至可以在对植物中的除草剂性能进行任何视觉检测之前验证甘蔗作物中毒。
