| Abstract/Summary |
The effects of N-cyclohexylbenzothiazol-2-sulfenamide (CBS) and its photodegradation products on inhibition of photosynthetic electron transport in spinach chloroplasts and growth of roots and shoots of Sinapis alba L. were investigated. The solution of CBS in CCl4 was irradiated with a mercury lamp for 1.0—7.5 h without and with application of ultrasound (25 kHz, 16 W cm−2). Using GC the presence of following benzothiazole derivatives was confirmed: benzothiazole, benzothiazole-2-thiol, 2-(cyclohexyldisulfanyl)benzothiazole, di(benzothiazol-2-yl)disulfane, and 2-chlorobenzothiazole. In the investigated concentration range (1.5—148.5 mg dm−3) CBS and its photodegradation products showed pronounced stimulating effects on the growth of Sinapis alba L. On the other hand, the tested reaction mixtures containing photodegradation products of CBS inhibited oxygen evolution rate in the suspension of spinach chloroplasts and the photosynthesisinhibiting activity of the reaction mixtures depended on the time of irradiation as well as on the application of ultrasound.
