Monitoring of Herbicide (Atrataf 50W) Toxicity by Using Pollen as Indicators-Pollen of Five Cultivars of Petunlia axillaris BSP.:Further Evidence of a Criticism of Berg (1973), Brandt (1974), Rasmussan (1977), Navara, Horvath and Kaleta (1978), Mhatre (1980-Ph.D. Thesis), Mhatre, Chaphekar,

Germinability of pollen of F series of white-flowered and F-24 series of light-violet-, pink-, violet-, white-flowered and F-48 series of white-flowered cultivars of Petunia axillaris was suppressed even by the lowest concentration (10^-17 mg/ml) of atrataf 50W tried.
