Effects of pyrimethanil on pollen meiosis of tomato plant (Lycopersicon lycopersicum Mill.)

Abstract

Effects of Mythos SC 300 (300 g/l pyrimethanil), a fungicide on tomato plants were studied by observation of pollen meiosis. The fungicide was applied at double the recommended dosage (250 ml/100 l tap water). The anthers of flower bud fixed in Carnoy's fluid were stained with 2% aceto-orcein. The fungicide caused various anomalies in pollen meiosis, decrease in pollen yield and consequently influenced future seed formation.

Some Observations on Plant Karyology and Investigation Methods

“…There are several ways to prepare aceto-orcein and aceto-carmine and the procedures given below have been tested many times and satisfactory results were obtained [10,19,37,41].…”

Effects of Fosetyl-Al, a fungicide on meiosis of <i>Lycopersicon esculentum</i> Mill.

“…Reddy and Rao (1981) observed positive relationship between chromosomal damages and pollen sterity in Chilli. Chromosomal abnormalities like, ring shaped, linear, binding and polar distortion were also observed in various studies (Kesercioğlu and Çalı 2007, Bilaloğlu 1985, Devadas et al 1986, Pusztaı 1983and Badr 1979.…”
